Zusammenfassung:C \ PrbI\DCC\KMH\I2H772_) DOC-17)UX/2(I(1 A multi-zonal monofocal ophthalmic lens comprising: a first lens surface and a second lens surface disposed opposite the first lens surface; the first lens surface 5 comprising: a first zone having sag surface characterized by a first base radius of curvature and a first asphericity constant; and a second zone surrounding the first zone and having sag surface characterized by a second base radius of curvature and a second asphericity constant; the second base radius of curvature being unequal to the first base radius of curvature and/or the second asphericity constant being unequal to the first asphericity 10 constant; the zones 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.
