Variable optic ophthalmic device including liquid crystal elements
摘要
Methods and apparatuses for providing a variable optic insert (300) 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 castmolded from a silicone hydrogel. The various ophthalmic lens entities may include electroactive liquid crystal layers to electrically control refractive characteristics. The variable optic insert comprising at least a portion within the optical zone and comprising an insert front curve piece (320) and an insert back curve piece (310), wherein a back surface of the front curve piece and a front surface of the back curve piece have differing surface topology at least in the portion within the optical zone, 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; and a layer of liquid crystal material operatively associated with the variable optic insert.
