Ophthalmic lens viewing sets for three-dimensional perception of stereoscopic media

FIELD OF USE

0001This invention describes methods, apparatus and devices related to Ophthalmic Devices that allow for three-dimensional viewing or perception of specialized two-dimensional media or stereoscopic media, and more specifically, in some embodiments, an Ophthalmic Lens with a Media Insert or a Multi-piece Rigid Insert within which or upon which are components.

BACKGROUND

0002Traditionally, an Ophthalmic Device, such as a contact lens, an intraocular lens, or a punctal plug included a biocompatible device with a corrective, cosmetic, or therapeutic quality. A contact lens, for example, can provide one or more of vision correcting functionality, cosmetic enhancement, and therapeutic effects. Each function is provided by a physical characteristic of the lens. A design incorporating a refractive quality into a lens can provide a vision corrective function. A pigment incorporated into the lens can provide a cosmetic enhancement. An active agent incorporated into a lens can provide a therapeutic functionality. Such physical characteristics may be accomplished without the lens entering into an energized state.

0003Recently, the popularity of three-dimensional viewing of specialized two-dimensional images, such as, for example, stereoscopic imagery, has grown. This popularity has prompted a surge in 3-D movies and a development of 3-D televisions. Often, three-dimensional viewing requires a specialized device that interprets the two-dimensional image before the image reaches the eye, allowing the Three-dimensional Perception from the combined Filtered Translations.

0004More recently, active components have been included in a contact Lens, and the inclusion may involve the incorporation of energizing elements within the Ophthalmic Device. The relatively complicated components to accomplish this effect may derive improved characteristics by including them in insert devices which are then included with standard or similar materials useful in the fabrication of state of the art Ophthalmic Lenses. It may be desirable to improve the process, methods, and resulting devices for realizing inserts of various kinds. It may be anticipated that some of the solutions for energized inserts may provide novel aspects for non-energized devices and other biomedical devices. Accordingly novel methods, devices, and apparatus relating to Ophthalmic Lens Viewing Sets are therefore important.

DETAILED DESCRIPTION OF THE INVENTION

0022The present invention includes methods and apparatus for manufacturing a Viewing Set of Ophthalmic Lenses with translation filters, wherein the Viewing Set allows for Three-dimensional Perception of stereoscopic media. In addition, the present invention includes the resulting Viewing Set of Ophthalmic Lenses.

0023Stereoscopic media involves the simultaneous display of two images, wherein the brain will interpret the two images as a single image with three-dimensional properties. Some limited media allow for Three-dimensional Perception without requiring a filtering device, such as, for example, in side-by-side stereoscopic imagery, where viewers may force Three-dimensional Perception by crossing their eyes. Other media include autostereoscopic technology, wherein the filtering mechanism is included within the projection device, such as, for example, handheld gaming devices that utilize a parallax barrier. Because the filtering mechanism is included within the projection device, the Three-dimensional Perception does not require further filtering equipment, though the filtering is tailored to a predefined set of eyes and may not be as effective on users with dissimilar characteristics.

0024Other types of stereoscopic media require additional filtering devices, and, often, the filtering device is portable and personal, wherein each viewer must use the filtering device to experience Three-dimensional Perception. Common filtering devices include "3-D glasses", which are structured like a pair of glasses, wherein each "lens" includes a Translating Filter. When used together to view the stereoscopic media, the two filters allow the brain to experience Three-dimensional Perception.

0025The resurgence of stereoscopic media has prompted development of the technology. For example, creating stereoscopic media has become more complex allowing for nuanced three-dimensional imagery, wherein the viewer may feel immersed in the filmed environment. Another example includes the development of home theater televisions that utilize stereoscopic media, wherein standard television programming, such as sports, may be Three-dimensionally Viewed. Stereoscopic media may become even more prevalent in the future.

0026The most prevalent stereoscopic media requires some variation of 3-D glasses. However, the glasses are often cumbersome and expensive, especially for home theaters. In addition, the "lenses" are static, and eye movement shifts the perspective, which may be jarring over prolonged periods, such as, while watching a stereoscopic film. Stereoscopic televisions often include one or two sets of 3-D glasses, inherently limiting the number of viewers. Additionally glasses are available, but are often cost-prohibitive.

0027Accordingly, the present invention includes an alternative filtering device for Three-dimensional Perception of stereoscopic media. In general, according to some embodiments of the present invention, a Rigid Insert may be embodied within an Ophthalmic Lens via automation, which may place the insert a desired location relative to a mold part used to fashion the lens. The embodiments that place the various components into the Ophthalmic Lens may employ one or more steps where components are sealed and adhered into place or components are encapsulated.

0028In some embodiments with Media Inserts, an Energy Source is placed in electrical communication with a component, which may be activated on command and draws electrical current from the Energy Source included within the Ophthalmic Lens. A component may include for example, a semiconductor device, an active or passive electrical device, or an electrically activated machine, including for example: Microelectromechanical systems (MEMS), nanoelectromechanical systems (NEMS), or micromachines. Subsequent to placing the Energy Source and component, a Reactive Mixture can be shaped by the mold part and polymerized to form the Ophthalmic Lens.

0029In the following sections detailed descriptions of embodiments of the invention will be given. The description of both preferred and alternative embodiments are exemplary embodiments only, and it is understood that to those skilled in the art that variations, modifications and alterations may be apparent. It is therefore to be understood that said exemplary embodiments do not limit the scope of the underlying invention.

0031Proceeding to <figref idref="f0001">Figure 1</figref>, an embodiment of a Viewing Set of Ophthalmic Lenses 100, 150 with dichroic translation filters 101, 151 is illustrated. In some embodiments, a left Ophthalmic Lens 100 may include a left dichroic translation filter 101, and a right Ophthalmic Lens 150 may include a right dichroic translation filter 151. As shown in cross section, the left dichroic filter 111 may allow a specific array of red, green, and blue (RGB) light, and the right dichroic filter 161 may allow a different array of RGB light. When the right Ophthalmic Lens 160 and the left Ophthalmic Lens 110 are used as a Viewing Set, the combined filtered translation may allow for Three-dimensional Perception of the stereoscopic image.

0032The Ophthalmic Lenses 100, 150 may also include other passive elements, such as, for example, cosmetic coloration, including iris patterns, or vision-correcting aspects.

0033Proceeding to <figref idref="f0002">Figure 2</figref>, an alternate embodiment of a Viewing Set of Ophthalmic Lenses 200, 250 with polarizing translation filters 201, 251 is illustrated, wherein the Ophthalmic Lenses 200, 250 may translate circularly polarized light. There are multiple techniques for polarizing light through a transmissible material including, for example, wire grids, employment of Brewster's angles plates, and employment of birefringent or biaxial materials.

0034A left Ophthalmic Lens 200 may include a left translation filter 201, and a right Ophthalmic Lens 250 may include a right translation filter 251. As shown in cross section, the left translation filter 211 and the right translation filter 261 may linearly polarize circularly polarized light, wherein the two translation filters 211, 261 may polarize the light at different angles.

To further facilitate placement on the eye, the Stabilizing Feature 212, 262 may contain a tint, wherein the user may see how the Ophthalmic Lens 200, 250 may orient on the eye.

0037Proceeding to <figref idref="f0003">Figure 3</figref>, an embodiment of a Viewing Set of Ophthalmic Lenses 300, 350 with translation filters 301, 351 is illustrated, wherein the translation filters 301, 351 may be included in an encapsulated Rigid Insert 304, 354.

0038In some embodiments, the Rigid Insert 304, 354 may be included in an Ophthalmic Lens 300, 350, which may comprise a polymeric biocompatible material.

The Rigid Inserts 304, 354 may be fully encapsulated with the Ophthalmic Lenses 300, 350. Accordingly, the Rigid Inserts 304, 354 may not be limited to biocompatible material.

0040In some embodiments, the Rigid Insert 304, 354 may comprise a film of dichroic materials. Some embodiments may include layers of films, each contributing to the translation filters 301, 351. For example, the top and bottom films may act to protect the internal dichroic film, and the protecting layers may be three-dimensionally formed through a thermo forming process.

0041As shown in cross section, the Rigid Insert 314, 310 may be fully encapsulated by the polymerized RMM 313, 363. The encapsulating process may place the Rigid Insert 314, 364 in the Optic Zone of the Ophthalmic Lenses 310, 360. In some embodiments, the Rigid Insert 314, 364 may extend beyond the Optic Zone. In such embodiments, the periphery portion of the Rigid Insert 314, 364 may provide passive functionalities. For example, the portion outside of the Optic Zone may include cosmetic coloration, such as, for example, iris patterns; or, the periphery may include an active agent. In some embodiments, the active agent may provide relieving hydration, which may be useful when the user's blink rate is low, such as, for example, while viewing stereoscopic media.

0042Proceeding to <figref idref="f0004">Figure 4</figref>, an alternative embodiment of a Viewing Set of Ophthalmic Lenses 400, 450 with Rigid Insert 404, 454 is illustrated. In such an embodiment, the Rigid Insert 404, 454 may translate circularly polarized light. A left Rigid Insert 404 may include a left translation filter 401, and a right Rigid Insert 454 may include a right translation filter 451.

0043In some embodiments, polarization features 401, 451 may be thermoformed onto an insert piece 404, 454. In some embodiments, such features 401, 451 may be imparted to insert pieces 404, 454 through properties of thin film starting materials. Alternatively, the thermoforming process may be sufficient to impart the polarization features 401, 451.

0044The filtering function may be developed in a Rigid Insert 404, 454 through a single technique or by a combination of techniques. For example, in some embodiments, the polarizing features 401, 451 of an Ophthalmic Lens 400, 450 may include wire grids and dichroic materials. In some embodiments, the Rigid Insert 404, 454 may be thermoformed from a thin sheet of metallic or conductive filaments or lines deployed in a parallel fashion to form a wire grid.

0045As shown in cross section, the Rigid Inserts 414, 464 may comprise multiple layers. For example, the front layer 420, 470 may comprise a quarter wave plate, and the back layer 421, 471 may comprise a linear polarizer. and the right translation filter 461 may linearly polarize circularly polarized light, wherein the two translation filters 411, 461 may polarize the light at different angles. In some embodiments, where the left Ophthalmic Lens 410 and the right Ophthalmic Lens 460 are used as a Viewing Set, the left filtered translation and the right filtered translation may combine to allow for Three-dimensional Perception of a stereoscopic image.

0046Thermoforming techniques may add alignment features to the front layer 420, 470 and the back layer 421, 471, which may allow for precise control of the differing polarizing orientations of the right Rigid Insert 464 and the left Rigid Insert 414. The polarizing features may be enhanced by thermo forming the Rigid Insert 464, 414 to include a Three-dimensional Surface.

0047For example, when the Rigid Insert 404, 454 is assembled into an Ophthalmic Lens 400, 450, the Rigid Insert 404, 454 may be positioned with alignment features into a cavity formed between a front curve Mold and a back curve Mold. The Rigid Insert 404, 454 may be encapsulated by filling the area between the Mold Pieces with Reactive Monomer Mixture and then polymerizing the RMM. Numerous Reactive Monomer Mixtures may be consistent with the formation of molded Ophthalmic Devices, including, for example, those capable of forming hydrogel lenses, such as silicone hydrogel.

0048Some embodiments of the Ophthalmic Lenses 400, 450 may include Stabilizing Features 402, 452, wherein the Stabilizing Features 402, 452 may orient the Lenses 400, 450 on the eye and limit rotation. Stabilizing Features 402, 452 may be particularly significant in embodiments where the translation filter 401, 451 depends on a specific alignment. For example, the Viewing Set may include similar translation filters 401, 451, and two unique filtered translations may be caused by different alignments of the translation filters 401, 451 in the left Ophthalmic Lens 400 and the right Ophthalmic Lens 450.

0049Including the translation filters through a Rigid Insert may allow for additional passive functionalities imparted to the encapsulating material. For example, some embodiments may include a tinting in the Optic Zone. In some embodiments, the color tint may be an innate property of the encapsulating material. In other embodiments, the coloring property may be added to the encapsulating material by depositions, applications, or other means of imparting a color to the Reactive Monomer Mixture. A color tinting may provide a variety of functions in an Ophthalmic Lens. For example, the tinting may be useful in excluding or attenuating wavelengths of light as may be the function of shading ambient sunlight.

0050The tinting may provide safety functions where the tinting may block certain wavelengths thereby shielding or partially shielding the effect of intense radiation sources such as, for example, lasers or welding arcs. In some embodiments, the tinting 881 may address medical conditions in some users, who may benefit from either passing or rejecting certain wavelengths from entering the user's eye.

0051Proceeding to <figref idref="f0005">Figure 5</figref>, an exemplary embodiment of a Viewing Set of Ophthalmic Lenses 500, 550 that includes a Media Insert 504, 554 is illustrated. In some such embodiments, the Media Insert 504, 554 may include the translation filters 501, 551 within a variable optic portion. Various energization elements may be included in regions outside the Optic Zone of the insert. The energization elements may include, for example, integrated circuits, passive electronic components, energization elements, and activation elements that may control the nature of the translation filters 501, 551.

0052The Media Insert 504, 554 may comprise multiple insert pieces, wherein the insert pieces may be formed through thermoforming techniques. For example, alignment features may allow two insert pieces and to lock into place without direct force to the Optic Zone portion or the component. This may allow for more delicate, but precise, assembly of a Media Insert 504, 554. For example, liquid crystal may be susceptible to damage caused by pressure or heat. In some embodiments, the front piece insert may be locked into the back piece insert, and the locking between the alignment features may maintain the positions of the two pieces. The Media Insert 504, 554 may be further secured by applying focused pressure or heat to more robust portions of the Media Insert 504, 554.

0053In some embodiments, the translation filters 501, 551 may comprise liquid crystal, wherein the activation of the liquid crystal may darken the translation filters 501, 551. The darkening may be sufficient to block light. The Viewing Set may provide Three-dimensional Perception through alternating activation of the left translation filter 501 and the right translation filter 551. In some embodiments, the left Ophthalmic Lens 500 may be in electrical communication with the right Ophthalmic Lens 550, which may allow the left Media Insert 504 to synchronize with the right Media Insert 554.

0054The frequency of the alternating activation may be configured to specific refresh rates of the stereoscopic media. In some embodiments, the activation may be programmed for a single frequency. Other embodiments may include a variable alternating activation frequency. For example, the Media Insert 504, 554 may include a sensor that may recognize the refresh rate of the viewed media, and the Media Insert 504, 554 may adjust the alternating activation frequency accordingly.

0055In some embodiments, a separate sensor may recognize when the user is viewing stereoscopic Media. This sensor may be capable of triggering a stop in activation when Three-dimensional Perception is not required. The ability to restrict activation may extend the battery life of the Media Insert and may allow extended wear, as the alternating activation may impede non-Three-dimensional Perception.

0056Proceeding to <figref idref="f0006">Figure 6</figref>, an alternate embodiment of a Viewing Set of Ophthalmic Lenses 600, 650 that includes a Media Insert 604, 654 is illustrated. In some such embodiments, the translation filter 601, 651 may be passive elements included in the polymerized RMM, and the Media Insert 604, 654 may include an active meniscus-base lens 607, 657 in the variable optic region 607, 657. The meniscus-based lens may allow for multiple powers of vision correction. For example, the variable optic region 607, 657 may contain at least two immiscible fluids that form an interface between them that may act as a focal element. Various energization elements may be included in regions outside the Optic Zone of the insert. The energization elements may include, for example, integrated circuits, passive electronic components, energization elements, and activation elements that may control the nature of the meniscus based lens.

0057In other embodiments, the Media Insert 604, 654 may comprise an annular shape, wherein the annular Media Insert 604, 654 does not include a region in the Optic Zone. Such embodiments may provide non-ophthalmic functionalities, including, for example, administration of an active agent or monitoring a specific characteristic of the ophthalmic environment, such as glucose or temperature.

0058In some embodiments, the Ophthalmic Lenses 600, 650 may include a passive Rigid Insert, not shown, in addition to the Media Insert 604, 654. The Rigid Insert may provide additional functionalities to the Ophthalmic Lenses 600, 650 with translation filters 601, 651 included in the polymerized Reactive Monomer Mixture. In some embodiments, thermoforming may add colored design to the Rigid Insert, which may add a cosmetic function to an Ophthalmic Lens 600, 650. The colored design may be located outside of the Optic Zone of the Ophthalmic Lens 600, 650. In some embodiments, a printed pattern may be included in an annular Rigid Insert. Alternatively, the translation filter may be included in the Rigid Insert.

0059In some embodiments of Viewing Sets, the translation filters may be imperceptible when Three-dimensional Viewing is not required. Such embodiments may allow for extended use of the Ophthalmic Lens. Extended use may be significant in embodiments where the Ophthalmic Lenses provide functionalities in addition to the translation filters. For example, Ophthalmic Lenses that include translation filters may correct vision, add cosmetic coloration to the eye, monitor the ophthalmic environment, or a combination thereof. Accordingly, in such embodiments, the translation filters may be visually ignored when the user is not viewing stereoscopic media.
