1. An ophthalmic lens having an optical axis, the lens comprising a layer provided on a surface of a substrate, the layer having a base refractive index and including at least one gradient index optical element having an asymmetric refractive index profile, such that the at least one gradient index optical element focuses light from a distant point source on the optical axis to a point that is a first distance from the optical axis.
