Variable focus ophthalmic device including liquid crystal elements

摘要

This invention discloses methods and apparatus for providing a Variable Optic Insert into an Ophthalmic Lens. 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.

主权项

1. An energized ophthalmic lens device with a variable optic insert comprising:
an ophthalmic lens insert-encapsulating layer comprising an optical zone and a non-optical zone; a variable optic insert comprising at least a portion within the optical zone; an energy source embedded in the ophthalmic lens insert-encapsulating layer in at least a region comprising the non-optical zone; the variable optic insert comprising a layer of liquid crystal material; and at least a first layer of dielectric material proximate to the layer of liquid crystal material, wherein the first layer of dielectric material varies in thickness across a region within the optical zone.
