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

摘要

PROBLEM TO BE SOLVED: To provide a method and an apparatus for providing a variable optical insert into an ophthalmic lens.SOLUTION: A variable optical insert may have surfaces that have differing radii of curvature. A liquid crystal layer may be used to provide a variable optical function and, in some embodiments, the liquid crystal layer may comprise polymer networked regions of interstitially located liquid crystal material. An energy source is capable of powering the variable optical insert included within an ophthalmic lens. In some embodiments, the 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.
