Abstract
A method of manufacturing an electro-active lens is disclosed. The lens is manufactured by providing a lens blank having a front and back surface, a thickness, and an index of refraction. An electro-active element is placed on one of the front or back surfaces of the lens blank. A covering surface is then formed over the surface of the lens blank containing the electro-active element. In some embodiments, the electro-active lens may then be surfaced to provide a desired fixed optical power and edged to fit within a spectacles frame.
Claims25
A method of manufacturing an electro-active lens comprising:
- providing an electro-active element;
- and
- covering an exposed surface of the electro-active element to produce an electro-active lens;
- wherein the electro-active element comprises a plurality of pixels;
- and
- wherein the electro-active lens is capable of focusing an image from ambient light;
- wherein the electro-active element is connected to a power source;
- and
- wherein the power source is connected to a hinge screw of a spectacle frame.
A method of manufacturing an electro-active lens comprising:
- providing an electro-active element;
- covering an exposed surface of the electro-active element to produce an electro-active lens;
- wherein the electro-active element comprises a plurality of pixels,
- the electro-active lens is capable of focusing an image from ambient light,
- the exposed surface of the electro-active element is covered by a lens blank,
- the lens blank is selected from a group comprising a semi-finished blank, an unfinished lens blank, a lens wafer, a preformed optic and a finished lens blank,
- the lens blank corrects a wearer's refractive error other than myopia, hyperopia, presbyopia, and regular astigmatism, and
- the electro-active element corrects a spherical error of the wearer.
A method of manufacturing an electro-active lens from a lens blank comprising
- providing a lens blank comprising a front and back surface, a thickness and an index of refraction, the front or back lens blank surface having a recess;
- placing an electro-active element containing a plurality of pixels within the recess of the lens blank surface;
- and
- forming a covering layer over the surface of the lens blank containing the electro-active element;
- wherein the electro-active element is capable of focusing an image in ambient light;
- and
- wherein the covering layer is formed by way of curing an optical resin.
