Eyeglass with enhanced ballistic resistance

Technical field of the invention [0001] The present inventions generally relate to attachment systems for glasses, and more particularly to methods and devices for fixing an eyeglass lens in a manner that provides excellent ballistic resistance and stability of the eyeglass lens.

Description of the Prior Art [0002] In recent years, many different improvements have been made in the field of glasses, in particular regarding glasses intended for use in active sports or as fashionable sunglasses. The design of these glasses has achieved many functional benefits, maximizing light capture, reducing optical distortion and increasing the level of user comfort compared to previous glasses for active sports.

such as peripheral, [0003] In addition, many other improvements have been made to increase the durability and strength of the glasses. For example, various durable eyeglass designs have been developed that allow eyeglasses to be durable even during accidents, impacts, stresses, and other forms of use or misuse. In addition, eyeglass lenses have also been developed that have increased ballistic protection. In this way, glasses can generally be resistant to breaking, bending or becoming useless in any other way.

SUMMARY OF THE INVENTION [0004] A continuous goal in the field of high-quality glasses, especially intended for use in action sports, at high speeds, or in military applications is to obtain glasses that exhibit better ballistic resistance and lens stability. Various improvements have been made that allow the user to quickly modify his eyeglasses, using the components and / or eyeglass lenses to be replaced, using the systems disclosed in US Patent Nos. 4,730,915, 5,387,949 and 7,347,545, the entire disclosure of each of which is incorporated herein. . Nevertheless, at least one of the embodiments disclosed herein reflects that in order to increase the ballistic resistance and stability of the eyeglass lens of the eyeglasses, additional support may be used for the replaceable or removable eyeglass lens.

[0005] The embodiments disclosed herein define, at least in part, a construction of durable glasses that allows the eyeglass lens to be held more securely in the glasses by the glasses frame. Glasses may include one or more retaining elements that can be used in conjunction with traditional eyeglass lens mounting elements, such as those in the systems disclosed in the above-referenced patents. However, in some examples of use, the retaining elements can be used independently of the traditional eyeglass lens mounting elements.

[0006] In some embodiments, in response to a ballistic event (such as bullet impact and / or blunt contact with an object), the retaining element may advantageously stop the eyeglass lens from performing translational and / or rotational movement in all directions when the eyeglass lens is connected and / or supported by a retaining element. This feature can be opposed to prior art eyeglass lens fastening elements in that the prior art eyeglass lens is generally prevented from translational and / or rotational movement in many, but not all directions, at a given point along the lens-frame border. In this way, the impact as a result of the ballistic event may cause removal, displacement or dismantling of the prior art eyeglass lens from the prior art frame.

[0007] For example, conventional removable uniform eyeglass lens systems comprise an upper eyeglass frame having a eyeglass lens groove facing downwards. The upper edge of the optical eyeglass lens is located inside the eyepiece groove. The eyepiece lens is held within the groove by a first interference fit on the first side edge of the eyeglass lens, and a second interference fit on the second side edge of the eyeglass lens. This can ensure secure attachment of the eyepiece lens and good resistance to movement of the eyepiece lens sideways relative to the eyepiece frame when gently using the glasses. However, at least the central portion of the eyeglass lens can be moved down and out of the eyeglass lens groove during the flexible reconfiguration of the glasses after impact. In this way, at least one of the embodiments disclosed herein reflects that prior art glasses do not provide sufficient ballistic resistance.

[0008] In contrast, the embodiments disclosed herein can securely hold the eyeglass lens relative to the eyeglass frame during and after ballistic impact. For example, the central portion of the eyeglass lens may be completely embedded within the eyepiece groove during and after impact.

[0009] Such embodiments, because they allow it to be safe, can be advantageous to hold the eyeglass lens by the eyeglass frame without undermining or spoiling the eyeglass

For example, and / or the optical properties of the lens, the eyeglass lens may be supported by the eyeglass frame in a manner that maintains the formed geometry of the eyeglass lens.

[0010] Furthermore, the embodiments disclosed herein can advantageously provide glasses in which the eyeglass lens can be easily removed and replaced by the user while allowing the user to mount the eyeglass lens so that the eyeglass lens exhibits better ballistic resistance and eyeglass lens stability.

[0011] For example, in some embodiments disclosed herein, glasses are provided comprising an eyeglass frame in which at least one eyeglass lens can be mounted. Glasses may include at least one retaining element or blockage of the eyepiece lens. The eyeglass lens retaining member or lock may be mounted on, carried or supported by the eyeglass frame and / or eyeglass lens. The retaining element may be adapted to engage at least a portion of the eyeglass frame and / or eyeglass lens. The retaining element may be adapted to attach the spectacle lens to the spectacle frame to prevent detachment from the spectacle frame in response to a ballistic event. For example, an eyeglass lens may be "separated" from the eyeglass frame when any part of the top edge of the eyeglass lens is pulled out of the eyepiece lens groove.

[0012] In some embodiments, the glasses may include at least one spectacle lens, spectacle frame, and at least one rotatable retaining element. The eyeglass frame can be adapted to be worn on the user's head. The at least one rotatable retaining element can be supported by an eyeglass frame and an eyeglass lens. The retaining element can be rotatable with respect to the eyeglass frame and with respect to the eyeglass lens to engage with the connecting portion of the eyeglass lens to prevent the eyeglass lens from separating from the eyeglass frame in response to a ballistic event.

[0013] Optionally, the at least one spectacle lens may include at least one lateral first connector. The spectacle frame may include at least one lateral second connector, a first temple and a second temple. The at least one lateral second connector of the eyeglass frame may be adapted to engage the at least one lateral first connector of the at least one eyeglass lens to support the at least one eyeglass lens in the user's field of view.

[0014] The retaining element or lock of the eyeglass lens may include at least one connecting structure to facilitate connection to the eyeglass lens. In addition, the eyeglass lens retainer or blockage may be a system or multiple elements that work to engage the eyeglass lens. Glasses may include at least one retaining element or blockage of the eyepiece lens. In addition, at least one retaining element can be located in the middle of the spectacle frame.

[0015] In some embodiments, the eyepiece retaining member or lock may include at least one clamp. The clamp can be attached along the eyepiece frame. The clamp may be located in the center portion and / or the side portion (s) of the spectacle frame, centered on the center line of the spectacle frame. The clamp may be operated by the user to secure the center portion and / or the side portion (s) of the spectacle lens to the spectacle frame.

[0016] As mentioned above, the glasses may optionally be configured such that at least one eyeglass lens comprises at least one first connector and the eyeglass frame comprises at least one second connector. The at least one eyeglass lens may be a single lens or a dual lens. The first eyeglass lens connector may attach to the second eyeglass frame connector to restrict the movement of the eyeglass lens relative to the eyeglass frame. For example, the first eyeglass lens connector may include opposite side connectors, and the second eyeglass frame connector may include opposite side connectors. The adapter (s) of the spectacle frame may include opposing lateral depressions and / or end projections. The eyepiece lens connector (s) may include corresponding opposing lateral projections and / or catches or depressions. For example, the recesses and or end protrusions of the eyeglass frame may be adapted to at least partially receive or engage with the protrusions and / or recesses of the spectacle lens. When attached together, the indentations and either end projections of the eyeglass frame and the indentations and or end projections of the eyeglass lens may limit the movement of the eyeglass lens relative to the eyeglass frame.

[0017] In some embodiments, at least one first eyeglass lens connector and at least one second eyeglass frame connector may be used with the retaining element, the eyeglass lens lock, or the clamp. For example, the eyeglass frame connector (s) may attach to the corresponding eyeglass lens connector (s) to attach the eyeglass lens to the eyeglass frame in the mounted position, while the clamp is used to attach the center portion of the eyeglass lens to the eyeglass frame to prevent detachment the eyepiece lens away from the eyeglass frame in response to a ballistic event. Thus, if the glasses were subjected to unexpected forces such as would result from dropping, precipitation or impact by the projectile, the spectacle lens would not tend to separate from the spectacle frame. However, a plurality of clamps may also be used to attach the eyeglass lens to the eyeglass frame along a plurality of points of the eyeglass lens.

[0018] In some embodiments, the clamp can be rotated relative to and / or around the eyeglass frame and / or eyeglass lens. In some embodiments, the clamp may be moved or shifted with respect to the spectacle frame and / or spectacle lens. For example, the retaining element may comprise a rotatable or slideable clamp that can be mounted on the spectacle frame or supported by the spectacle frame of the glasses. In some embodiments, the retention element may comprise a rotatable or slideable clamp that may be mounted on the eyeglass lens or supported by the eyeglass lens. The clamp can be adjusted or manually controlled by the user. The clamp can connect directly or indirectly to part of the eyeglass frame and / or eyeglass lens. In some embodiments, one or more clamps may connect directly or indirectly to a portion of a plurality of eyeglass lenses, such as a dual lens system.

[0019] In some embodiments, the clamp may include a connecting structure, such as a flap, that engages and / or interlocks with the connecting part or a suitable surface structure such as a recess or opening of the eyeglass frame and / or eyeglass lens.

[0020] For example, the eyeglass lens may include an opening or slot that can be connected and / or supported by a clamp flap. In some embodiments, the clamp may have a first pivot / slide position or a disengaged position in which the eyeglass lens can be freely removed downward from the eyeglass frame, allowing the eyeglass lens to be detached.

The clamp may also have a second pivot / slide position or connected position in which the eyeglass lens may be attached and / or supported relative to the eyeglass frame such that the eyeglass lens does not separate from the eyeglass frame in response to a ballistic event.

[0021] The clamp may have a hinged construction. For example, the clamp may be made as a tubular element that wraps around at least part of the eyeglass frame. The clamp may have a hinged, rotatable design in which the clamp rotates relative to or around at least a portion of the eyeglass frame to facilitate attachment of the eyeglass lens to the eyeglass frame. The clamp may also have a hinged, sliding design in which the clamp moves along at least a portion of the eyeglass frame to facilitate the attachment of the eyeglass lens relative to the eyeglass frame.

[0022] In some embodiments, the clamp may have a split ring structure having a slit or cut. The split ring may include or surround a portion of the eyeglass frame wrapping around, e.g., at least about 50% and / or less than or about 80% of the perimeter or perimeter of a portion of the eyeglass frame, with approximately at least about 20% and / or less than , or about 50% of the clamp forms a gap or cut. In an embodiment with a swivel clamp, the gap or cut may be configured such that at least a portion of the eyeglass lens may enter into it to secure the eyeglass lens relative to the eyeglass frame. In such embodiments, the flap may be located at one of the free ends forming a slit or cut.

[0023] In some embodiments, the slide clamp may engage the slit in the eyeglass lens. For example, the eyeglass lens may be mounted relative to the eyeglass frame with the clamp positioned near the eyepiece lens slot in the first displaced position or in the disengaged position. The clamp can then be moved inside the slit towards the second sliding position or connected position, thereby blocking the spectacle lens relative to the spectacle frame.

[0024] In some embodiments, the clamp may be adapted to be snapped onto the spectacle frame. The clamp may be pressed against the spectacle frame, with the part of the spectacle frame passing through a slit or cut in the clamp. In some embodiments, the clamp can be made of a flexible material such that the clamp bends, allowing the gap or cut to be enlarged so that the clamp can be attached to the eyepiece frame. The clamp can in this way be attached to the eyepiece frame without requiring pins, snaps or other elements. The embodiments disclosed herein can therefore provide better assembly and maintenance of glasses compared to other solutions. In addition, such a solution can be durable and durable, providing convenient and safe maintenance, despite the stresses and other forces that can act on the glasses. In addition, the clamp can rotate with a slit or split mixed from the first rotational position or the disengaged position in which part of the eyepiece lens may enter the slit or cut into the second rotational position or joined position, wherein the slit or cut is rotated such that the clamp engages with a portion of the eyeglass lens. Rotation of the slit or cut may allow a quick and reliable connection to the eyepiece lens.

[0026] In some embodiments, the clamp may form an external profile that narrows or connects to the surface of the ra eyeglass frame. For example, the clamp may define an outline or outer shape that connects to the outline or outer shape of the spectacle frame. In some embodiments, the outline or outer shape may merge only in one of the first or second rotational positions. For example, a mismatch in the contour may provide a visible and tactile indication that the clamp is in the disengaged position, while the clamp and the eyeglass frame generally have a uniform, smooth contour when the clamp is in the connected position.

[0027] In some embodiments, the clamp may rotate and / or slide about a horizontal axis such that the flap generally moves in a forward and backward direction to engage the spectacle lens. For example, the flap can be rotated within a generally vertical plane front back to align with the spectacle lens to engage the spectacle lens. In addition, the flap can be moved along the eyepiece frame when moving the clamp within a generally vertical front-back plane to line up with the eyepiece lens to engage the eyepiece lens.

[0028] In an illustrative example, the clamp can rotate and / or move about a vertical axis. In such glasses, the flap can be rotated within a generally horizontal plane to align with the eyeglass lens, in a generally vertical plane to engage the eyeglass lens.

[0029] For example, the connecting structure of the retaining element may comprise a flap that is pivotally connected to the spectacle frame so that the flap can pivot about a vertical axis. Optionally, the retaining element may comprise a roller that connects the retaining element to the spectacle frame. In addition, the retaining element may optionally comprise an actuating element which is mechanically connected to the flap so that the actuating element can be used to rotate the flap.

[0030] In some embodiments, the eyeglass frame may include a recess or opening configured to receive and / or support the retaining element. For example, the recess or opening of the eyeglass frame may support the retaining element such that force (exerted in at least one direction) on the retaining element is transferred to the eyeglass frame. The recess or opening of the spectacle frame may optionally be configured to support the retaining element such that forces exerted in different directions on the retaining element are transferred to the spectacle frame.

[0031] For example, in embodiments where the retaining member rotates and / or moves about a horizontal axis, the retaining member may engage the horizontal section of the spectacle frame. As mentioned above, the connection may be a snap connection. The retaining element can fit into the horizontal section and can rotate around the horizontal section. In addition, the retaining element can be inserted or embedded within a horizontally extending recess or space in the spectacle frame.

[0032] In addition, in illustrative examples in which the retaining element rotates and / or moves about a vertical axis, the retaining element may engage with the vertical section of the spectacle frame. For example, the retaining element may fit the vertical section and rotate around the vertical section. In addition, the retaining element can be inserted or embedded within a vertically extending recess or space in the spectacle frame.

[0033] The retaining element may also comprise a plurality of clips arranged along the frame of the glasses. In such embodiments, the eyeglass frame may be configured with or without opposed fasteners, recesses and / or end projections that are used to engage the fasteners with protrusions and / or eyepieces of the eyeglass lens to secure the lens in the mounted position. For example, many clamps can be used as exclusive connectors for attaching the eyepiece lens and preventing it from separating from the frame.

[0034] Furthermore, the retaining element can be formed separately from the spectacle frame. For example, the retaining element can be connected to the spectacle frame and can be rotatable or slideable in view of the spectacle frame. In some embodiments, the retention element can be moved (disengaged) connected from the first position (or position to the second position (or position to engage the spectacle lens). For example, the spectacle frame and the retaining element may also be configured to allow a predetermined range of rotational or axial movement of the retaining element. In one embodiment, the eyeglass frame may include one or more stop elements that can engage in one or more respective fasteners or recesses in the retaining element. The retaining element may rotate in a given direction until the stop element of the spectacle frame contacts the catch or recess of the retaining element to limit the further rotation of the retaining element.

[0035] For example, in embodiments in which the retaining member comprises a rotatable clamp, the clamp may rotate between two or more rotational positions, with the clamp buffer elements and the eyepiece frame limiting the movement of the clamp in one or more positions. For example, the clamp may be configured to include an interior having one or more protrusions or depressions that engage with one or more protrusions or depressions of the spectacle frame. In some embodiments, the stop elements may not be visible when assembled. In addition, the connection between the rotating clamp and the spectacle frame may also create the desired interaction between the respective stop elements and the spectacle frame.

[0036] In addition, embodiments are shown in which the eyepiece lens includes a connecting portion that can be connected and / or supported by a retaining element. The connecting portion of the eyeglass lens may comprise at least one of a recess, surface contour, cutout, projection, slot, hole and other such surface structures formed in many shapes and / or sizes. For example, in some embodiments, the connecting portion may be an opening that extends over the thickness of the spectacle lens. The connecting structure can also be a notch that extends through the thickness of the eyeglass lens and extends inwardly from the circumference of the eyeglass lens. In addition, some embodiments may be configured such that the frame includes a connecting portion that can be connected by a retaining element that is supported by an eyeglass lens.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT [0038] Although the present description sets out the specific details of the various embodiments, it is obvious that the description is only illustrative and should not be interpreted in any way as limiting. In addition, although specific embodiments of the present inventions may be disclosed or shown in the context of single or dual lens eyeglass systems, such embodiments may be used in both single and dual lens eyeglass systems. In addition, although the embodiments disclosed herein can be used with glasses that have replaceable or removable lenses, embodiments are also contemplated in which the glasses do not provide for the provision of replaceable or removable lenses.

[0039] Furthermore, although individual embodiments may be disclosed or shown in connection with spectacle frames having partial orbitals, such embodiments may be used with spectacle frames having both full and partial orbitals. The retaining elements and structures in accordance with the embodiments disclosed herein can also be used to hold an eyeglass lens or multi-lens structure inside goggles, such as ski goggles or motorcycle goggles. The support structures can be used either as a main connector or as an auxiliary connector to cooperate with other eyeglass lens retention systems. In addition, the various uses of such embodiments and their modifications that may occur to those skilled in the art are also encompassed by the general concepts described herein.

[0040] For example, some embodiments may provide glasses comprising an eyeglass frame and at least one retaining element or blockage of the eyeglass lens. The spectacle frame may be configured to support at least one lens in the user's field of view. The spectacle frame may include a first temple and a second temple. The eyeglass frame can be worn on the user's head. The at least one retaining element may be supported by an eyeglass frame and / or by at least one lens. The retaining element can be moved relative to the eyepiece frame and / or the lens. For example, the at least one retaining element can be rotated relative to the eyeglass frame and relative to the eyeglass lens to lock the at least one eyeglass lens relative to the eyeglass frame. At least one retaining element may be hinged. In some embodiments, the retaining element may attach to the connecting portion of the spectacle lens to prevent the spectacle lens from separating from the spectacle frame in response to a ballistic event. In addition, certain embodiments may be configured such that the eyeglass frame includes a connecting portion that can be joined by a retaining element that is supported by the eyeglass lens.

[0041] The eyeglass lens retaining member or lock may be configured to rotate relative to the eyeglass frame and / or eyeglass lens to engage with a suitable one of the eyeglass lens and / or eyeglass frame. The lens retaining member or lock may be permanently or releasably attached to the eyeglass frame and / or at least one eyeglass lens. The retaining element may comprise a clamp located in the middle of the spectacle frame. The clamp can be operated by the user to secure the center portion of the eyeglass lens to the eyeglass frame. The retaining element may be movable from a first position in which the eyeglass lens can move freely relative to the eyeglass frame to a second position in which the eyeglass lens is attached to the eyeglass frame.

[0042] For example, the retaining element can rotate about a generally horizontal axis with respect to the spectacle frame to connect the spectacle frame and / or the eyepiece lens. In addition, the retaining element may comprise a rotatable clamp mounted on the spectacle frame and / or spectacle lens. The rotatable clamp may comprise a connecting structure that connects the connecting part of the spectacle lens and / or spectacle frame.

[0043] The rotary clamp may also comprise a generally tubular or cylindrical body, and the connecting structure may comprise a connecting flap extending generally circumferentially with respect to the cylindrical body. The tubular or cylindrical body may be adapted to engage with the recess of the spectacle frame to attach the retaining element to the spectacle frame. The flap may have a first position in which the eyeglass lens is movable relative to the eyeglass frame and a second position in which the flap engages with the eyeglass lens to attach the eyeglass lens relative to the eyeglass frame. For example, the clamp flap may engage the eyeglass lens at an angle relative to the horizontal plane of between at least about 5 degrees and / or about 40 degrees or less. In some embodiments, the caliper flap may attach to the eyepiece lens at an angle of about 19.2 degrees to the horizontal.

[0044] In addition, the retaining element may fit into the recess of the spectacle frame to be rotated about the longitudinal axis of the spectacle frame. For example, the retaining element may snap into the recess. In some embodiments, the connecting portion of the eyeglass lens may include one element of a recess and an opening that can be connected through the connecting structure of the rotatable clamp.

[0045] In an illustrative example, the retaining element can rotate about a generally vertical axis, relative to the eyeglass frame, to engage the eyeglass frame and / or eyeglass lens. For example, the retaining element may include an actuating handle and at least one flap that is rotatable upon rotation of the handle. The flap may extend generally transversely to the generally vertical axis. The flap may have a first position in which the eyeglass lens is movable relative to the eyeglass frame and a second position in which the flap engages with the eyeglass lens to attach the eyeglass lens relative to the eyeglass frame. For example, the retaining element can rotate in a plane that generally lies in the same plane with at least a portion of the lens. In addition, the retaining element may comprise an elongated shaft extending between the handle and the flap. In addition, the frame may include a recess adapted to receive at least part of the retaining element to support the retaining element relative to the spectacle frame. In addition, the handle may be accessible to the user to actuate the retaining element.

[0046] The glasses may optionally be configured such that the at least one eyeglass lens comprises at least one first connector and the eyeglass frame comprises at least one second connector. The at least one eyeglass lens may be a single lens or a dual lens. The first eyeglass lens connector may attach to the second eyeglass frame connector to restrict the movement of the eyeglass lens relative to the eyeglass frame. For example, the first eyeglass lens connector may include opposite side connectors, and the second eyeglass frame connector may include opposite side connectors. The adapter (s) of the spectacle frame may include opposing side depressions and or end projections. The eyepiece lens connector (s) may include corresponding opposing lateral projections and / or catches or depressions. For example, the indentations and / or end projections of the eyeglass frame may be adapted to at least partially receive or engage with the projections and / or indentations of the spectacle lens. When attached together, the indentations and either end projections of the eyeglass frame and the indentations and or end projections of the eyeglass lens may limit the movement of the eyeglass lens relative to the eyeglass frame.

[0047] In some embodiments, the spectacle frame connector (s) may include opposing lateral and lens connector protrusions and / or cavities (connectors) of the eyepiece cavity (s) and / or end protrusions.

The eyeglass frame connector (s) and the eyeglass lens connector may be joined to attach the eyeglass lens to the eyeglass frame in a mounted position. For example, the indentations and / or end projections of the eyeglass frame may be adapted to at least partially receive or engage with the projections and / or indentations of the spectacle lens. When attached together, the indentations and / or end projections of the spectacle frame and the indentations and / or projections of the spectacle lens may limit the movement of the spectacle lens relative to the spectacle frame. The eyepiece frame may include a groove for the eyepiece lens. The eyeglass lens groove may extend at least partially along the eyeglass frame to receive at least part of the eyeglass lens within.

[0048] In some embodiments, at least one eyeglass lens may include a connecting portion. In addition, the eyeglass frame may have a generally horizontal longitudinal axis and a pair of temples extending backwards relative to the eyeglass frame. The eyeglass frame may be adapted to support at least one eyeglass lens in the user's field of view. In addition, the glasses can be configured such that at least one retention mechanism is connected to the spectacle frame and is rotatable about the longitudinal axis of the spectacle frame. The retention mechanism may include a connecting structure extending therefrom. The holding structure may be movable from a first position in which the eyeglass lens can move freely relative to the eyeglass frame to a second position in which the holding structure engages with the connecting part of the eyeglass lens to attach the eyeglass lens to the frame.

[0049] The frame may also include at least one stop element adapted to limit the rotational position of the retaining element relative to the eyepiece frame. The retention mechanism may also include at least one stop element corresponding to at least one stop element on the spectacle frame. The stop elements may be adapted to contact each other to limit the rotational position of the retaining element relative to the spectacle frame.

[0050] The retaining element of the embodiment and the second with at least one retention mechanism of some examples may include a first buffer which interact with the buffer element of the spectacle frame.

it may have various shapes and structural features, such as including a generally cylindrical body with a connecting structure extending generally circumferentially therefrom. For example, at least one stop element of the retaining element can be formed along the inner surface of the retaining element. In addition, at least one stop element of the retaining element may include a recess and at least one stop element of the spectacle frame may include a projection.

[0051] The connecting structure of the retention mechanism may include a flap that connects to the connecting part of the spectacle lens at an angle between at least about 5 degrees and / or about 40 degrees or less relative to a line that is perpendicular to the lens. In addition, in some embodiments, the flap can engage the connecting portion of the eyeglass lens at an angle between at least about 10 degrees and / or about 20 degrees or less relative to a line that is perpendicular to the lens. For example, the tab may attach to the connecting portion of the eyeglass lens at an angle of about 19.2 degrees.

[0052] Referring to Figure 1, an embodiment of the present inventions is shown. In this embodiment, glasses 10 are shown that include a pair of temples 12, 14, an eyeglass frame 16, a retaining element 18, and an eyeglass lens 20. The eyeglasses 10 shown in Figure 1 are configured so that the eyeglass lens 20 can be removed and replaced. However, in other embodiments, the spectacle lens cannot be removed or replaced. Nevertheless, such embodiments can provide the stability of an eyeglass lens to provide increased ballistic resistance similar to that of Figure 1.

and to an embodiment [0053] Figure 2 shows an embodiment of an eyeglass lens 20 for use in glasses 10. The eyeglass lens 20 may be configured to be supported by an eyeglass frame 16. For example, the eyeglass lens 20 may include one or more connecting parts which can be combined with one or more eyeglass retainers to support the eyeglass lens. In addition, other constructions may be used to support the eyeglass lens. For example, the eyeglass frame may include one or more fasteners, such as recesses and / or end projections, and the lens may include one or more fasteners such as protrusions and / or recesses, which may engage with the eyeglass frame fastener (s). For example, Figure 2 shows opposing lens protrusions mounted in a recess (s) and / or an end projection (s) of the spectacle frame. However, the use of structures such as protrusions and recesses in the spectacle frame and spectacle lens is optional and may be omitted in some embodiments. For example, additional structures for the retaining element (s) and connecting part (connecting parts) may be unnecessary where two or more retaining elements and connecting parts are disposed along the edge of the eyepiece lens.

[0054] It is obvious with reference to Figures 1-4 that the lens 20 of the glasses 10 can be selectively removed and replaced by the user. For example, a user may replace the eyeglass lens 20 with an eyeglass lens having a different shade or shape. In some embodiments, the user may connect locking connectors, such as the protrusions and / or the catches or recesses of the eyeglass lens 20 with suitable connectors, such as opposing recesses and / or the end projections of the eyeglass frame 16, to remove and replace the eyeglass lens 20.

[0055] For example, as shown in Figures 2 and 4, the eyepiece lens 20 may include fasteners, such as a pair of projections 30, 32, which may be embedded in the respective fasteners, such as end recesses 34, 36 of the spectacle frame 16. During for use when the protrusions 30, 32 enter the end recesses 34, 36 of the eyeglass frame 16, the lens 20 can usually be snapped and retained in the eyepiece lens groove of the eyeglass frame 16. Thus, in some embodiments, such a system can provide a further degree of retention of the eyeglass lens and its stabilization in addition to that provided by the retaining element.

[0056] According to the embodiment shown in the Figures

4, the lens 20 may also include a connecting portion or coupling structure 50. The connecting portion 50 may include at least one portion of the eyepiece lens 20, which may be one of a recess, surface contour, cutout, projection, slot, hole and other such constructions surface, and can be formed in many shapes and / or sizes. For example, in the embodiment shown, the connecting portion 50 is shown as an opening that extends over the thickness of the eyepiece lens 20. The connecting portion 50 is shown as a single opening, or it can be formed as multiple holes. The connecting portion 50 can extend generally parallel to the line that is perpendicular to the eyepiece lens 20 (as shown in, for example, Figure 11A). In addition, the connecting portion 50 may extend generally transversely to a line that is perpendicular to the eyepiece lens 20 (as shown for example in Figure 11B).

[0057] The connecting portion 50 can be located at any point along the lens 20, and preferably at any point along the lens-frame border 52 of the eyeglass lens 20. The lens-frame border can be defined as the part or portion of the eyeglass lens along which the eyepiece lens and the border eyeglass frames overlap or merge with each other. For example, with reference to Figures 1 2, the lens-frame border 52 is generally the upper section of the eyeglass lens 20 adjacent the upper edge of the eyeglass lens 20, which is embedded in the groove 54 of the eyeglass frame 16 (shown in Figure 4). In this way, although a single connecting portion 50 is used in the embodiment of the eyeglass lens 20 shown in Figure 2, other embodiments of the eyeglass lens 20 may be constructed that include two or three, or four or more connecting portions 50 located along the border of the lens - frame 52.

may also be configured, [0058] In addition, as mentioned above, although the connecting portion 50 is shown as an opening, the connecting portion 50 may also include a projection, a clip and / or other shapes and sizes of the connecting parts that allow the eyeglass lens 20 to interconnect with retaining element 18. In addition, as noted above, the eyeglass lens 20 may comprise a uniform or dual lens system. For example, one or more connecting parts may be used in any eyeglass lens of the dual lens system as needed. In addition, the eyepiece lens 20 can be mounted inside the orbital eyepiece frame. The border of the lens 52 may extend around the circumference of the eyeglass lens 20 (or the circumference of both lenses in the dual lens system). In such embodiments, one or more connecting portions may be selectively located along lower portions, transverse portions or middle portions (such as near the nose lens opening), wherein the spectacle frame includes appropriate retaining means to connect to the respective portions portions. eyeglass lens (s) [0059] With reference to Figures 5-8, the function and operation of the embodiment of the retaining element 18 will now be described. In Figures 5-6 the retaining element 18 is located in the disengaged position 70. In addition, in Figures 7-8 the retaining element 18 is located in the connected position 72. It is obvious to the skilled person that when the retaining element 18 is in the disengaged position 70 , the retaining element 18 is not connected to the respective connecting part of the eyepiece lens 20. However, when the retaining element is in the connected position 72, the retaining element 18 can engage with the connecting portion 50 of the eyepiece lens 20 as shown in Figure 7.

[0060] To facilitate attachment to the connecting portion 50 of the eyepiece lens 20, the retaining element 18 may include a protrusion or recess that engages with the respective connecting portion 50. As shown in Figures 5-8, the retaining element 18 may include a flap 80 which extends from the body 82 of the retaining element 18. In the embodiment shown, the tab 80 may be configured to fit into the opening or be embedded in the opening of the connecting portion 50. The tab 80 of the retaining element 18 provides a push-fit connection to prevent detachment of the eyepiece lens 20 from the eyepiece frame 16 or exit from the groove 54 of the eyepiece lens of the eyeglass frame 16.

[0061] As also shown in Figures 5-8, in some embodiments, the retaining member 18 may be rotatable relative to the eyeglass frame 16 and relative to the eyepiece lens 20. Furthermore, the retaining member 18 may be a hinged clamp that defines an outer profile that narrows and engages with the surface of the eyeglass frame 16. For example, the clip 18 may define the outline or outer shape that engages with the outline or outer shape of the eyeglass frame 16. In some embodiments, the outline or outer shape can only merge in one of the first or second rotational positions. For example (as shown in Figures 5-6), a mismatch in the contour may be a visible and tactile indication that the clamp 18 is in the disconnected position, while the clamp 18 and the eyeglass frame 16 generally have a uniform, smooth contour when the clamp is in the connected position (as shown in Figures 7-8).

[0062] With reference to Figures 9-11B, embodiments of the retaining element 18 are shown as a rotatable element which is connected to the spectacle frame 16. The body 82 of the retaining element 18 may be generally annular or tubular in shape that wraps around at least part of of the eyeglass frame 16. For example, the body 82 may have the shape of a split ring (as seen in side views of Figures 9-11) that includes or surrounds a portion of the eyeglass frame 16. The retaining element 18 may wrap around, e.g., at least about 50% and / or less than or up to about 80% of the perimeter or perimeter of a portion of the eyeglass frame 16, with at least 20% and / or less than or up to about 50% the retaining element 18 forms a gap or cut 90.

[0063] In addition, the slit or cut 90 may be configured such that at least a portion of the lens can enter it to attach the eyepiece lens to the eyepiece frame 16. In this way, when rotated to the disengaged position 70, the slit or cut 90 may align with a portion of the eyeglass frame 16, such as a groove 54. As a result, the retaining member 18 may allow at least a portion of the eyeglass lens 22 to pass into the groove 54 of the eyeglass frame 16. Furthermore, in the embodiments shown in Figures 5-11B, the flap 80 may be located at one of the free ends forming a gap or cut 90. The retaining element 18 may be rotated from the first pivot position or the disengaged position to the second pivot position or position combined in which the tab 80 and the gap or cut 90 are rotated so that the tab 80 of the retaining element 18 engages with part of the eyepiece lens. Rotation of the slit or cut may allow a quick and reliable connection to the eyepiece lens.

[0064] In some embodiments, the retaining element 18 may be adapted to snap onto the spectacle frame 16. In embodiments where the retaining element is clamp 18, the clamp may be pressed against the spectacle frame 16, with the portion of the eyeglass frame 16 passing through. through the gap or cut 90 in the clamp. In some embodiments, the clamp may be made of a flexible material such that the clamp bends, allowing the gap or cut 90 to be enlarged, so that the clamp can be attached to the eyepiece frame 16. The clamp can thus be attached to the eyepiece frame 16 requiring dowels, latches or other elements. The embodiments disclosed herein can therefore provide better assembly and maintenance of the glasses compared to other solutions. In addition, such a solution can be durable and durable, providing convenient and safe maintenance despite stress and other forces that may affect the glasses.

[0065] In some embodiments, the retaining member 18 may be configured to be mounted on the eyeglass lens 22 such that the retaining member 18 engages with a suitable support structure on the eyeglass frame 16 when the eyeglass lens 22 is mounted on the eyeglass frame 16. For example, the retaining element 18 may be mounted such that the retaining element 18 is movable relative to the eyepiece lens 22. However, the retaining element 18 may be fixed to the spectacle lens 22. The retaining element 18 may be fixed to the spectacle lens 22. The retaining element may be detachably attached to the spectacle lens 22. Accordingly, in some embodiments it is not necessary such that the clamp or retaining element 18 is part of the eyeglass frame 18 or is carried or supported by the eyeglass frame. Various embodiments and features discussed herein with respect to the retaining element 18 in the embodiments where the retaining element is carried by the spectacle frame 16 or supported by the spectacle frame may be included in the embodiments where the retaining element 18 is mounted for the eyepiece lens 22.

[0066] As shown in Figure 10, the eyeglass lens 20 can be embedded in the groove 54 of the eyeglass frame 16 when the retaining element 18 is in the disengaged position 70.

Then, when the retaining element 18 is rotated to the connected position 72 as shown in Figure 11, the tab 80 of the retaining element 18 is moved to a position within the opening of the connecting portion 50 of the eyepiece lens 20. As a result, the eyepiece lens 20 can be generally limited before moving in in all directions at the point of connection with the eyeglass frame 16 in the retaining element 18.

[0067] For example, the glasses 10 may exhibit better ballistic resistance and stability of the eyeglass lens during use. Furthermore, embodiments of glasses may be used in which one or more retaining means may be used to attach the spectacle lens to the spectacle frame. In such embodiments, the eyeglass lens can be connected to the eyeglass frame in a manner that does not distort the eyeglass lens or impair its optical properties. As a result, the eyeglass embodiments disclosed herein may not only provide better ballistic resistance and eyeglass lens stability, but may also provide better optical properties.

[0068] In addition, as shown in the embodiments of Figures 9-11B, the glasses may include a movement restriction mechanism. For example, retaining element 18 may include one or more stop elements that are configured to interact with one or more stop elements on the eyepiece frame 16. For example, retaining element 18 may include rear stop elements 92 and upper and lower front stop elements 93, 94 that are adapted to interact with respective of rear stop element 96 and front stop element 98 of the spectacle frame 16. As shown in the Figures 9-11, stop elements 92, 93, 94, 96, 98 may limit the rotation of the retaining element 18 relative to the eyepiece frame 16. For example, the use of stop elements 92, 93, 94, 96, 98 can facilitate accurate movement from the disengaged position 70 to the connected position 72 and vice versa. Furthermore, in some embodiments, the stop elements 92, 93, 94, 96, 98 can also be used to lock the retaining element 18 relative to the eyepiece frame 16 so that mutual rotational movement is prevented. Such a feature may be advantageous when the retaining element 18 is moved to the connected position 72 in which it can be snapped into place or otherwise retained to prevent inadvertent disengagement.

[0069] In the embodiment shown, the eyeglass frame 18 includes a pair of stop elements 96, 98 formed as projections extending from the outer surface of the bridge of the eyepiece frame 16. Although the two stop elements 96, 98 are shown in the drawing, it can be also used a single stop element. Furthermore, in embodiments where two stop elements are used, the stop elements may perform different functions with respect to the retaining element 18.

[0070] For example, the rear stop element 96 may be relatively larger than the front stop element 98 and, above all, provide a restriction against rotation in a given direction. The front stop element 98 may perform a connecting function that seeks to limit or substantially immobilize the rotational position of the retaining element 18. The rear stop element 96 may attempt to limit the rotational position of the retaining element 18.

[0071] In use, making some initial effort to overcome the connection between the lower front stopper element 98 and the lower front stopper element 94 of the retaining element 18, the retaining element 18 may move from the first rotational position or the disengaged position 70. Retaining element 18 it can rotate further until it is rotatably limited or stopped by the rear stopper 96 and the front stopper 92. In addition, the retaining element 18 may be substantially limited in the second pivoting or in-on position 72 due to the connection between the front stop element 98 and the upper front stop element 93. Although the embodiment shown in the drawing shows at least two stop elements of the retaining element 18 interacting with at least two stop elements of the spectacle frame 16, the movement limiting mechanism may include a single stop on the spectacle frame and a single stop on the retention element, while what the bumpers can interact with to provide rotational limitation and essentially fixed fixation of the rotational position.

[0072] Therefore, in such embodiments, in which the retaining element 18 comprises a rotating clamp, wherein the clamp can rotate between two or more rotational positions with the buffers or with the buffer elements 92, 93, 94, 96, 98 a clamp and an eyeglass frame 18 limiting the clamp in one or more positions. As shown in the drawing, the retaining element 18 may include an inner surface having one or more recesses 92 that connect to one or more protrusions that connect to one or more recesses of the eyeglass frame 16. In some embodiments, the bumper may be hidden from view when it is assembled. In addition, the connection between the rotatable clamp and the eyeglass frame can also create the desired interaction between the respective latch bumpers and the eyeglass frame.

[0073] Although Figures 9-11B show embodiments of the retaining member 18 as rotatable relative to the eyeglass frame 16, the retaining member 18 may be configured to rotate or slide relative to the eyeglass frame 16. In some embodiments, the retaining member 18 can be pivotally connected to part of the eyeglass frame 16. However, in the embodiment shown in the drawing, the retaining element 18 is configured to rotate around the eyeglass frame 6 to allow the flap 80 to connect to the connecting portion 50 of the eyeglass lens 20.

[0074] Furthermore, the retaining element 18 may comprise an elastic material such as compressible or elastic material located at least along the flap 80 of the retaining element 18. As a result, the ballistic event will not cause damage in the connection between the retaining element 18 and the connecting part 50. In such embodiments, the flap 80 may be formed of such an elastic or elastic material or comprise a coating, layer or one or more surface elements formed of elastic or elastic material. The retaining element 18, such as the tab 80 and / or elastic or resilient material, may have a modulus of elasticity that is less than the modulus of elasticity of the spectacle lens. In addition, the retaining element 18, such as the tab 80 and / or elastic or resilient material, may have a modulus of elasticity that is smaller than the modulus of elasticity of the spectacle frame. Accordingly, at least part of the retaining element 18 can dampen or absorb force or vibration from the ballistic event.

[0075] Furthermore, the retaining element 18 can be configured such that when rotating the retaining element 18 and engaging with the connecting portion 50 of the eyeglass lens 20, the eyeglass lens 20 can be inserted into the groove 54 to attach the eyeglass lens 20 inside the groove 54. Such a feature can be facilitated by using the cam movement of the retaining element 18 or the cam interaction between the flap 80 and the connecting part 50.

[0076] In some embodiments, the tab 80 of the retaining element 18 may engage the connecting portion 50 of the eyepiece lens 20 in the connected position (as shown in Figures 11A-11B) at the desired connection angle

100 fixed to maximize the stability, maintenance and flexibility of glasses in response to a ballistic event.

[0077] The connection angle 100 may be defined as the angle measured between the flap 80, i.e. the angle between the longitudinal or circumferential center line or axis of the flap 102, and the line 104 that is perpendicular to the eyepiece lens 20. The perpendicular line 104 may be a line that is perpendicular to the eyepiece lens 20 approximately in the connecting portion 50 of the eyepiece lens 20.

[0078] In some embodiments, the line 104 may be generally parallel to the axis 106 of the connecting portion 50, as shown in the embodiment of Figure 11A. Furthermore, in some embodiments, the flap axis 102 may be generally parallel to the longitudinal center line or axis 106 of the connecting portion 50 of the eyepiece lens 20. For example, as shown in the embodiment of Figure 11B, the flap axis 102 may be generally parallel to the axis 106 of the connecting portion 50 and oriented transversely to the perpendicular line 104 of the eyepiece lens 20.

[0079] The connection angle 100 may be oriented to provide optimal retention of the eyeglass lens 20 relative to the eyepiece frame 16. For example, in each of the embodiments shown in Figures 11A-11B and in other embodiments, the connection angle 100 relative to the horizontal plane may be between at least about 5 degrees and / or about 40 degrees or less. In addition, in some embodiments, the flap 80 may engage the connecting portion of the eyeglass lens at a connection angle 100 relative to the horizontal plane between at least 10 degrees and / or about 30 degrees or less. In some embodiments, the connection angle 100 may be about 12 degrees. In other embodiments, such as the embodiment of Figure 11B, it has been found that the connection angle 100 of approximately 19.2 degrees gives excellent results in ballistics.

[0080] Furthermore, the rotation range of the retaining element 18 between the coupled position and the disengaged position may be between at least about 10 degrees and / or about 180 degrees or less. For example, as shown in Figures 10-11B, the retaining member 18 can rotate about 45 degrees from the connected position to the disengaged position.

[0081] In some embodiments, the tab 80 of the retaining element 18 may engage with the connecting portion 50 of the eyeglass lens 20 by means of the front end 110 of the tab 80 extending through the connecting portion 50. For example, Figures 11A-B show that front end 110 extends to the second face or through the width of the eyepiece lens 20. However, front end 110 can extend only partially to the connecting portion 50 or beyond the connecting portion 50. For example, the front end 110 may extend through the connecting portion 50 between at least about 5 degrees and / or about 90 degrees or less. In this way, the front end 110 can be rotated downward from the eyepiece frame 16, through the eyepiece lens 20, and back toward the eyepiece frame 16. In some embodiments, the front end 110 can snap or connect to the eyeglass frame 16 to achieve connection locked in connected position.

[0082] Referring now to Figures 12-19, an illustrative example of glasses having a retention mechanism is shown. Figure 12 is a perspective view of glasses 300 that include an eyeglass frame 302, a pair of temples 304, 306 extending backwards from the eyeglass frame 302, eyeglass lens 308, and retention mechanism 310. The retention mechanism 310 can be hidden inside the eyeglass frame 302, so that the glasses 300 maintain the appearance of conventional glasses, while exhibiting excellent ballistic properties.

[0083] Figure 13 shows an eyeglass lens 308 for use with glasses. The eyeglass lens 308 may be adapted to be supported by the eyeglass frame 302. For example, the eyeglass lens 308 may include one or more connecting portions that can be connected to one or more eyeglass retaining elements for supporting the eyeglass lens. In addition, other constructions may be used to support the eyeglass lens. For example, the eyeglass frame may include one or more fasteners, such as opposite end recesses, and the eyeglass lens may include one or more fasteners, such as protrusions, which can be embedded in the end well (s) of the spectacle frame. However, the use of fasteners such as protrusions and end recesses is optional and may be omitted. For example, structures in addition to the retaining element (s) and the connecting part (connecting parts) may be unnecessary where two or more retaining elements and connecting parts are spaced apart along the edges of the eyepiece lens.

[0084] The eyeglass lens 308 may include fasteners, such as a pair of projections 320, 322, which may be embedded in suitable fasteners, such as end recesses 324, 326 of the eyeglass frame 302. In addition, the eyeglass lens 308 may include an upper edge or border 330. In use, when the protrusions 320, 322 are inserted into the apertures 324, 326 of the eyeglass frame 302, the top edge or border 330 of the eyeglass lens 308 can generally be snap fitted and held in the groove 332 for the lens of the eyeglass frame 320. In this way, this solution can provide a further degree of maintenance and stabilization of the eyeglass lens in addition to that provided by the retaining element.

[0085] According to the example shown in Figures 12-19, the eyepiece lens 308 may also include a joining portion 350. The joining portion 350 may include at least one portion of the eyeglass lens 308, which may be one element of a surface contour, cutout, projection, and other such surface structures, and can be formed in a variety of shapes and / or sizes. For example, the connecting portion 350 is that extends in thickness. In addition, the connecting portion 350 is shown as a single cut-out or can be formed as multiple cut-outs. In addition, the connecting portion 350 may be formed to include a narrowed section 352 and a wide section 354.

from the recess, slot, hole shown as a notch, 308 eyepiece lens.

[0086] Referring now to Figure 15, an example of a retaining member 360 has been shown. The retaining member 360 may be adapted to connect and attach the eyeglass lens 308 to the eyeglass frame 302. For example, the retaining member 360 may be located in one of the connected position and disconnected position. In the connected position, the retaining element 360 may block, connect and / or otherwise attach at least a portion of the eyeglass lens relative to the eyeglass frame 302. In the disconnected position, the retaining member 360 may allow the eyeglass lens 308 to move freely relative to the eyeglass frame 302. In addition, the retaining member 360 can be manually operated by the user to allow the user to replace eyeglass lenses.

[0087] In the example illustrated, the retaining member 360 may include a switch or handle 362 and at least one flap 364. The retaining member 360 may be adapted to rotate about a generally vertical axis relative to the glasses 300. The handle 362 may be operated by the user. The retaining element 360 may include an elongated shaft 366 extending between the handle 362 and the flap 364. In addition, some solutions may be configured such that the retainer 360 includes a pair of flaps 364. As shown in the drawing, the flap (flaps) 364 may extend generally in opposite horizontal directions and be attached to the lower end or bottom of the retainer 360.

[0088] The flap 364 may be located next to the eyepiece lens 308 to engage the eyepiece lens 308, such that the flap 364 may be located in a connected or disengaged position with respect to the eyepiece lens 308 to connect to the eyepiece lens 308. Connected and disconnected positions retaining 360 relative to the eyeglass frame 302 are shown in Figures 17 and 18. In addition, Figure 19 shows the retaining element 360 connected to the eyepiece lens 308 in a connected position.

[0089] Figure 14 is an enlarged perspective view of the glasses 300 and the retention mechanism 310. Figure 16 is a front cross-sectional view of the frame 302 of the glasses 300 taken along the line of Figure 12. As shown in the drawing, the eyeglass frame 302 may include a recess 370 configured to support the retaining element 360 shown in Figure 15. Figure 16 for the eyepiece lens,

The recess 370 may also show a groove 332 extending along the frame 302 configured to allow the flap 364 of the retainer 360 to pass down toward the groove 332 to the eyepiece lens. In addition, the recess 370 may include a handle receiving section 372 at its upper end to accommodate at least a portion of the handle 362 of the retaining member 360. As shown in Figure 14, the recess 370 may include a rotatable, stepped arrangement of slots. The slots may be configured to allow the flap 364 of the retaining member 360 to rotate when it is inserted into the recess 370, which rotation may limit the axial or vertical movement of the retaining member 360 (and inadvertent removal of the retaining member 360 from the recess 370 ). In this way, the retaining element 360 can be firmly seated in the recess 370 and held by the recess. In use, the recess 370 may allow the retainer 360 to rotate in it with the handle 362 rotated within the section 372 of the recess 370. In addition, the frame 302 may include a bulge 374 that causes interference and / or friction with respect to the movement of the handle 362 above it. In this way, inadvertent rotation and detachment of the retaining element 360 can generally be prevented.

[0090] In addition, as shown in Figures 17 and 18, when the retaining element 360 is located in the recess 370, the flap 364 can be located inside or extend within the groove 332 for the spectacle lens. Accordingly, the flap 364 can be rotated so that the retaining member 360 is in the disengaged position, as shown in Figure 17. When the retaining element 360 is in the disengaged position, the eyepiece lens 308 may be located inside the eyepiece lens groove 332 with a flap 364 fitting into the narrowed section 352 of the connecting portion 350 of the eyepiece lens 308. In addition, as shown in Figure 19, the retaining element 360 it can be rotated to a connected position such that at least one flap 364 rotates to enter the widened section 354 of the connecting portion 350 of the eyepiece lens 308. The retaining element 360 can thus be rotated in a plane that generally lies flush with the connecting portion 350 of the spectacle lens. In this way, the retaining element 360 can rotate within the connecting portion 350 of the eyepiece lens 308 to selectively connect or disengage with the eyepiece lens.

[0091] The example shown in Figures 12-19 allows the retainer 360 to block or engage the eyeglass lens 308 relative to the eyeglass frame 302. Especially at the upper edge or border 330 of the eyeglass lens 308 mounted in the eyepiece lens groove 332 and flap 364 connected to the connecting portion 350 of the eyepiece lens 308, the eyepiece lens 308 can be generally restrained from translational and rotational movement relative to the eyepiece frame 302. The ballistic strength of the glasses can be significantly increased with this design.

[0092] The retention element shown herein can provide excellent ballistic resistance to the lens and the eyeglass frame. The retaining element can be integrated into the eyeglass frame, carried or supported by the frame. The retaining element can also be formed as a separate part that can be built into existing glasses. The retaining element can resist the rotational movement or the forward movement of the spectacle lens relative to the spectacle frame at one or more connection points between the spectacle lens and the spectacle frame.

the retaining element may comprise a part of the frame and / or a part formed separately from the eyeglass frame that attaches to the part of the eyeglass lens.

Additionally, the eyeglass [0093] Some of the embodiments discussed herein provide for the use of a retaining element that performs the function of joining the eyeglass frame separately from the function of joining the eyeglass lens. However, the retaining element can attach both the eyepiece frame and the eyepiece lens together. For example, the retaining element may engage the projection of the spectacle frame on which the spectacle lens is mounted, thereby connecting the spectacle frame and connecting and limiting the movement of the spectacle lens.

[0094] Embodiments of the glasses disclosed herein may ensure that the spectacle lens is not substantially separated from the spectacle frame in response to a ballistic event. In addition, embodiments of the glasses may be configured such that force transmitted to the eyeglass lens is also transferred to the eyeglass frame, essentially maintaining the connection between the eyeglass lens and the eyeglass frame. For example, although the lens of such glasses may be damaged (cracked or chipped), the eyeglass lens cannot be broken or the eyepiece frame is displaced. This ballistic resistance can provide excellent protection for the user.

in addition, the retaining element may comprise resilient material, such as compressible or elastic material located at least along part of the retaining element. For example, the tab, connector, body or other structure or component may be formed of and / or contain one or more flexible materials. As a result, the ballistic event will not cause damage at the connection between the retaining element and the connecting part. In some embodiments, the tab of the retaining element may be formed of an elastic or elastic material or may comprise a coating, layer or one or more surface elements formed of the elastic or elastic material. The retaining element such as a flap and / or elastic or resilient material may have a modulus of elasticity which is smaller than the modulus of elasticity of the spectacle lens. Furthermore, the retaining element, such as the tab and / or elastic or resilient material, may have a modulus of elasticity that is smaller than the modulus of elasticity of the spectacle frame. Accordingly, at least a portion of the retaining element can dampen or absorb force or vibration from the ballistic event.

[0096] Glasses may include a plurality of retaining elements that connect the eyeglass lens and / or eyeglass frame to secure the eyeglass lens relative to the eyeglass frame. For example, the lens of the glasses may be connected and / or supported at two or more points along its upper edge or border.

[0097] In an embodiment that includes a uniform lens, the spectacle lens may be attached and / or supported on at least both side sides and in the central portion thereof. For example, the unitary lens may be attached to and / or supported by an eyeglass frame using a first retaining structure on the left side of the center line and a second retaining structure on the right side of the center line. The support constructions may include any of the latches or other mechanisms disclosed herein. The first retaining structure may be centered on a point that is within the left transverse one-third of the length of the frame, measured from hinge to hinge. The second retaining structure may be centered on a point that is within the right transverse one third of the frame length. A third retaining structure, located within the central one third of the frame length, preferably in the middle, can also be used. Four, five or more retaining structures may also be used, depending on the operation desired. Usually, the support structures can be arranged symmetrically along the length of the frame, or as a mirror image through the plane of symmetry (anatomical centerline).

[0098] In an embodiment that includes dual lenses, each eyeglass lens may be connected and / or supported by at least one retaining element. For example, the dual lens may be attached to and / or supported by an eyeglass frame using a first retaining structure on the left side of the center line and a second retaining structure on the right side of the center line. In some embodiments, the dual lens may be attached by three or more retaining elements, for example on both side sides and in the central portion thereof. Alternatively, the dual lens may be attached by a single retaining element and by a connection between the dual lens and the eyeglass frame, such as with a protrusion, latch or flap that connects to the eyepiece recess. As with the homogeneous lens discussed above, the support structures can usually be arranged symmetrically along the length of the frame, or as a mirror image through the plane of symmetry (anatomical centerline).
