VARIABLE OPTIC OPHTHALMIC DEVICE INCLUDING LIQUID CRYSTAL ELEMENTS

摘要

Methods and apparatuses for providing a variable optic insert into an ophthalmic lens as set forth. 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 comprising:
a variable optic insert comprising at least a portion within the optical zone and comprising an insert front curve piece and an insert back curve piece, the variable optic insert further comprising a non-optical zone; an energy source embedded in the variable optic insert in at least a region comprising the non-optical zone; a single layer of aligned liquid crystal material operatively associated with the variable optic insert, wherein the single layer of aligned liquid crystal material interacts with a first index of refraction to a first linear polarization orientation of incident light and with a distinct second index of refraction to a second linear polarization orientation of incident light, wherein the first polarization orientation of incident light is orthogonal to the second polarization orientation of incident light; and wherein the differential interaction of the single layer with the first linear polarization orientation of incident light forms a first focal characteristic different from a second focal characteristic determined by interaction of the single layer with the second linear polarization orientation of incident light; and wherein the light emerges from the ophthalmic device with the difference in the first focal characteristic from the second focal characteristic due to the interaction of the different linear polarization components with the single layer of aligned liquid crystal.
