Methods and apparatus for ophthalmic devices including cycloidally oriented liquid crystal layers |
摘要 |
This invention discloses methods and apparatus for providing a variable optic insert into an ophthalmic lens. A liquid crystal layer may be used to provide a variable optic function and in some examples, an alignment layer for the liquid crystal layer may be patterned in a cycloidally dependent manner. The patterning may allow for a polarization dependent lens in some examples. An energy source is capable of powering the variable optic insert included within the ophthalmic lens. In some examples, 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. |

1. A contact lens device with a variable optic insert positioned within at least a portion of an optical zone of the contact 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 regions of liquid crystal material aligned in a pattern across at least a first portion of the variable optic insert that varies with a cycloidal pattern, wherein locations of orientations in liquid crystal orientation aligning with a radial axis across at least a first portion of the optic insert has a parabolic dependence on a radial dimension. |
