Variable focus lens by small changes of the equatorial lens diameter

The present invention relates to an alternate focal lens comprising: - a rigidly defocable synthetic lens body having two transparent membranes that engage an ectopic axis and encircles the eponymal axis with a strikingly expandable peripheral edge, from which the perimeter and peripheral cavity are bordered by a transparent floss is filled with a solid impregnable solid fluid and a means for expanding the perimeter extending substantially to the aptic axis in a position plane, wherein the expansion means is a symmetrically-exerting force exerted by the lens peripheral surface direction. The present invention relates to a method for increasing the eptopic performance of a lustrously defibrillable lens, according to which the ectectic axial section of the invention has two orthographic refractive surfaces, as well as an elastic-synthetic, rigidly defoamable transparent refractive body located between the aisle axle oscillator and the two refractive surfaces, wherein the flange has an initial quench state having a quench diameter and a peripheral diameter of not more than 5% of the elongated equatorial diameter in the plane essentially perpendicular to the etiopic axis increase. ŕ
