Abstract:
An electro-active lens is presented which utilizes a surface relief structures and an electro-active material, with a change in refractive index facilitating the change in optical properties. A molded structure and a liquid crystal are used to form a diffractive lens. In addition to the classical approach of utilizing diffractive optics and multiple Fresnel zones to form a lens, an additional structure is placed between Fresnel zones in order to improve the diffraction efficiency across the visible spectrum, and reduce chromatic aberration.

Claim (Index 1):
An electro-active lens comprising:\n a first substrate; a second substrate; a liquid crystal material disposed between the first substrate and the second substrate; and a surface relief structure formed in the first substrate opposite the second substrate, the surface relief structure defining a Fresnel lens having a plurality of concentric rings and at least one prism structure disposed between a pair of concentric rings in the plurality of concentric rings.
