Method of manufacturing an electro-active lens
A method of manufacturing an electro-active lens is disclosed. The lens is manufactured by providing a lens blank having a front and back surface, a thickness, and an index of refraction. An electro-active element is placed on one of the front or back surfaces of the lens blank. A covering surface is then formed over the surface of the lens blank containing the electro-active element.
