A multi-zonal monofocal ophthalmic lens (60) comprises a first lens surface (68a) and a second lens surface (68b) disposed opposite the first lens surface (68a). The first lens surface (68a) comprises a first zone (70) having a sag surface characterized by a first base radius of curvature, and a second zone (72) surrounding the first zone (70) and having a sag surface characterized by a second base radius of curvature, which differs from the first base radius of curvature. The zones are configured to focus light entering the zones from a distant point source to substantially a single point such that the light substantially falls within the range of the depth-of-focus of a spherical lens having an equivalent focal length.
