VARIABLE OPTIC OPHTHALMIC DEVICE INCLUDING SHAPED LIQUID CRYSTAL ELEMENTS WITH NANO-SCALED DROPLETS OF LIQUID CRYSTAL

摘要

According to the present invention, disclosed are 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 droplets which are nano-scaled. 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.
