Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. An ophthalmic lens device with a variable optic insert positioned within at least a portion of an 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 lay…
