Abstract
An aspect of the invention is directed to an ophthalmic lens, comprising at least one optic comprising a lens zone. The zone is configured such that, when the lens is located in an average eye, for all object locations along an axis in a range from infinity to 1.0 diopters, for light having a wavelength 550 nm, the wavefront at the retina formed by the lens zone has the following characteristics 0.01 ≤ Z 40 Z 20 ≤ 5.0 , and 0.01≦|Z60|≦1.0 waves of 550 nm light. In some embodiments, 0.01≦|Z80|≦0.5 wave for light having a wavelength 550 nm.
