METHOD AND APPARATUS FOR OPHTHALMIC DEVICES INCLUDING SHAPED LIQUID CRYSTAL POLYMER NETWORKED REGIONS OF LIQUID CRYSTAL

摘要

The present invention relates to methods and apparatus for providing a variable optic insert into an ophthalmic lens. The variable optic insert may have surfaces within that have differing radii of curvature. 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 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.

主权项

1. An ophthalmic lens device with a variable optic insert positioned within at least a portion of the optical zone of the ophthalmic lens device, wherein the variable optic insert comprises:
a curved front surface and a curved back surface wherein the front surface and the back surface are configured to bound at least a portion of one chamber; an energy source embedded in the variable optic insert in at least a region comprising a non-optical zone; and a layer containing liquid crystal material positioned within the at least one chamber, wherein the layer includes polymer networked regions of interstitially located liquid crystal material.
