1. A contact lens, comprising:
a curved shell having a concave surface and a convex surface, the concave surface comprising at least a first zone and a second zone,
the first zone having a first curvature and the second zone having at least one second curvature;
the curved shell having a geometric center and the first zone having a first zone center;
the first zone center being offset peripherally from the geometric center, such that the first zone center coincides with the visual axis of the eye to which the contact lens is to be applied; and;
the curved shell having an overall diameter that approximates a corneal limbal diameter of the eye to which the contact lens is to be applied,
wherein the at least one second curvature further comprises a second curve and the second curve is centered on the geometric center and wherein the second curve is located immediately peripheral to a back shaping zone.
