A contact lens comprising an optically transparent lens body having a concave surface adapted to the patient's eye curvature and a convex surface. The lens has three regions: (1) an annular region of a first optical power; (2) at the center of said annular region, which is also at the optical center of said lens, a substantially pinhole-like aperture; and (3) a second larger annular region exterior to the first annular region.
