Title:
サイクロイド型配向の液晶層を備える眼用器具の方法及び装置
Document Type and Number:
Japanese Patent JP6448961
Kind Code:
B2
Abstract:
This invention discloses methods and apparatus for providing a variable optic insert into an ophthalmic lens. A liquid crystal layer (570) 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 for left and right circular polarised light. 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.
