METHOD AND APPARATUS FOR OPHTHALMIC DEVICES COMPRISING DIELECTRICS AND LIQUID CRYSTAL POLYMER NETWORKS

摘要

The present invention relates to a method and an apparatus for providing a variable optic insert into an ophthalmic lens. The variable optic insert may have surfaces having different radii of curvature therein. A liquid crystal layer may be used to provide a variable optic function and in some embodiments, the liquid crystal layer may comprise polymer networked regions of an interstitially located liquid crystal material. An energy source is capable of powering the variable optic insert included within the ophthalmic lens. In some embodiments, an ophthalmic lens is cast-molded from a silicone hydrogel. The various ophthalmic lens entities may include electroactive liquid crystal layers to electrically control refractive characteristics.
