Claim Text:
1. An electro-active ophthalmic lens comprising: a first element having a convex surface; a second element having a concave surface, the concave surface mated to the convex surface of the first element; a decentered electro-active zone, the decentered electro-active zone comprising an electro-active material disposed in a cavity formed between the convex surface and the concave surface, the electro-active material having a first refractive index in a first state and a second refractive index in a second state, the decentered electro-active zone having a centroid disposed below a mid-line of the first element; at least one pair of electrodes, disposed on the concave surface and the convex surface, that operatively applies an electric field to the electro-active material and operatively switches the electro-active material between the first state and the second state; and a framing layer, disposed around the electro-active material and between the concave surface and the convex surface, that operatively seals the electro-active material in the cavity; wherein:
