摘要：
System, ophthalmic lens, and method for extending depth of focus includes an optic having a clear aperture disposed about a central axis. The optic includes a first surface and an opposing second surface. The first and second surfaces are configured to introduce an asymmetric aberration to the eye while maintaining the in-focus visual acuity.
