titleOfInvention |
Method and apparatus for ophthalmic devices including gradient-indexed and shaped liquid crystal layers |
abstract |
This 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 radially dependent manner. The patterning may allow for the index of refraction of the optic device to vary in a gradient-indexed or GRIN manner. 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. 200 - 210 Figure 28 |
