A prosthetic, aspheric spectacle lens for aphakic patients comprising a posterior surface and an anterior surface having a spherically curved zone and an aspheric peripheral zone surrounding the central zone. The aspheric peripheral zone has an optimized amount of radially decreasing diopter power. An alternative embodiment has a zone intermediate of the central zone and the peripheral zone. The rate of radially decreasing diopter power change accelerates as the outer circumferential edge of the lens is approached.
