Abstract: A lens system is presented having a diffractive optical power region. The diffractive optical power region has a plurality of concentric surface relief diffractive structures. A greater portion of light incident on a diffractive structure near the center point contributes to the optical power than light incident on a diffractive structure peripherally spaced therefrom.
Abstract: A method for manufacturing an electro-active lens may be provided. The method may comprise the steps of providing a substrate having a first surface; disposing a mask over at least a portion of the first surface of the substrate, where the mask comprises an electro-static plastic material and where the mask has at least one opening; and depositing a layer of material through the at least one opening of the mask.
