1. An energized ophthalmic lens device, comprising:
a variable optic insert comprising at least a portion within an optical zone of the energized ophthalmic lens device and comprising a front curve piece and a back curve piece, wherein a back surface of the front curve piece and/or a front surface of the back curve piece have differing surface topology at least in the portion within the optical zone, the variable optic insert further comprising a non-optical zone;
an energy source embedded in the variable optic insert in at least a region comprising the non-optical zone;
a layer of liquid crystal material operatively associated with the variable optic insert; and
a layer of dielectric material proximate to the layer of liquid crystal material, wherein the layer of dielectric material varies in thickness across a region within the optical zone resulting in a varying electric field across the layer of liquid crystal material when an electric potential is applied across the layer of liquid crystal material.
