Claims1
A contact lens, comprising at least one thin zone in a lens periphery, the thin zone having a convex edge that is the outermost boundary of the optic zone of the lens and an innermost boundary of the thin zone formed by the shoulder and inwardly tapering ends wherein said lens has a circular or oval shape, the radius of the convex edge is consistent with the eyelid of a wearer of said lens, said convex edge is contoured so that the outermost edge corresponds to the contour of an eyelid and said thin zone is not centered about the vertical axis of the lens.
