Abstract

An electrically tunable progressive lens based on a liquid crystals(LC) is investigated and demonstrated. The proposed progressive LC lens could be a positive or a negative lens with a continuously tunable focal length. The progressive LC lens shows the spatially distribution in lens power ranging from +4D to -4D even though the lens power of the LC lens seems only -0.87D ~ +0.87 D calculated under parabolic wavefront approximation. The surprising results we present in this paper give LC lenses an insightful aspect and overrule the traditional statement of the limitation of lens power set by the optical phase difference in gradient-index LC lenses. It also paves a way in ophthalmic applications.
