A contact lens for application in practice of orthokeratology on an eye, including a curved shell having a concave surface and a convex surface. The concave surface includes a carrier zone and a back shaping zone, the back shaping zone having a first curvature and the carrier zone having at least one second curvature. The curved shell has a geometric center and the back shaping zone has a shaping zone center and the back shaping zone center is offset peripherally from the geometric center. The curved shell can have an overall diameter that approximates a corneal limbal diameter of the eye to which the contact lens is to be applied.
