Adaptive lens for vision correction

An adaptive liquid crystal lens system comprising a first substrate assembly, a second substrate assembly having a continuous phase profile, and a liquid crystal layer disposed between the first and second substrate assemblies. The first substrate assembly includes a first transparent substrate, an alignment layer, and a first conductive layer. The first conductive layer is disposed on the bottom surface of the first transparent substrate and adjacent to the top surface of the alignment layer. The second substrate assembly includes a second transparent substrate, a lens having a grooved surface, and a second conductive layer. The second conductive layer is a continuous layer adjacent to the lens. The liquid crystal layer is received in the grooves of the lens, and is adjacent to the bottom surface of the alignment layer. The alignment layer causes the liquid crystal material in the liquid crystal layer to be in a homeotropic state.
