An intraocular lens for providing enhanced vision includes an optic with a clearaperture over which light may be focused onto or near the retina of an eye. The opticincludes an anterior surface and an opposing posterior surface, the surfacesdisposed about an optical axis. The optic includes a central zone and an outerzone disposed about the central zone. The central zone comprises a pluralityof optical powers that progressively vary between a first optical power at a centerof the central zone and a second optical power at a periphery of the central zone,wherein the absolute value of the difference between the first optical powerand the second optical power being between predetermined values. The outer zonecomprises a third optical power and may also have a negative spherical aberration.The optic typically has a variation in optical power over the entire clear aperturethat is less than a predetermined amount.
