FLEXIBLE ELECTRO-ACTIVE LENS

摘要

A lens including a flexible refractive optic having a fixed refractive index, an electro-active element embedded within the flexible refractive optic, wherein the electro-active element has an alterable refractive index, and a controller electrically connected to the electro-active element wherein when power is applied thereto the refractive index of the electro-active element is altered.

1. An ophthalmic system comprising:
a base optic to provide a fixed base optical power, the base optic defining an optical axis; an electro-active element, disposed within the base optic, to provide at least one of a variable optical power or a variable transmittance; a power supply, disposed within the base optic radially outward from the optical axis, to supply electrical power to the electro-active element; and a conductive coil, disposed within the base optic radially outward from the optical axis, to charge the power supply via wireless charging.
