Abstract: A lens system may include a lens having a first electrode electrode layer, a second electrode layer, and a liquid crystal layer disposed between the first electrode layer and the second electrode layer. The lens may be divided into a plurality of lens segments that are concentrically arranged proceeding from a center to a radially outer periphery of the lens. An optical power of a first lens segment of the plurality of lens segments may be greater than an optical power of a second lens segment of the plurality of lens segments disposed radially outward relative to the first lens segment. Various other devices, systems, and methods are also disclosed.
