Abstract: 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.

Abstract: The present invention discloses 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, an alignment layer for the liquid crystal layer may be patterned in a hybrid manner. The patterning may allow for the lowering of the minimum electrical potential required to cause a shift in orientation of liquid crystal molecules within the ophthalmic device. 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 optical characteristics.

Abstract: An electro-optical filter made of a support in which an optical guide with a diffused channel waveguide and of a cover, that are created in borosilicate glass, and which includes a gap obtained by the use of suitable spacers, filled with a grating constituted of alternating strips of polymer and liquid crystal called POLICRYPS (Polymer Liquid CRYstal Polymer Slices), and with first electrodes that are coplanar to the support and next to the optical guide with a channel, that electrically control the grating making the filter tunable, and a manufacturing process.
