An intraocular lens for providingenhanced vision includes an optic having aclear aperture having an outer diameter. Theoptic has opposing first and second surfacesdisposed about an optical axis, the first surfaceincluding a cross- sectional profile. The opticfurther includes central and outer zones thatfill the entire clear aperture of the optic. Thecentral zone is disposed about the optical axishaving an outer diameter, the profile in thevicinity of the central zone having a constantradius of curvature or a radius of curvature thatincreases with increasing radius from the opticalaxis. The outer zone is disposed about thecentral zone, the profile in the outer zone havinga base curvature with a base radius of curvatureand a center of curvature, the profile inthe outer zone characterized in that, as the distancefrom the optical axis increases, the distancefrom the center of curvature of the basecurvature also increases.
