A contact lens formed from a transparent material having front and rear surfaces, wherein the rear surface has a base curve which is adapted to fit an eye of a wearer of the lens. The front surface has a central zone which has two different cylindrical curvatures which generate first and second central-zone refractive powers differing by an astigmatic factor. The front surface also has an outer zone with two different cylindrical curvatures which generate third and fourth central-zone refractive powers differing by the astigmatic factor, and an intermediary region, intermediate the central zone and the outer zone, having one or more contiguous intermediate zones, each intermediate zone having cylindrical curvatures differing by the astigmatic factor. The refractive powers from the central zone to the outer zone form monotonic progressions of decreasing values.
