Abstract
Described herein are systems and/or methods for forming an ophthalmic lens. An example method may comprise a step of determining a power profile based on a power profile function defined by a base optical power, an amount of spherical aberration at a radial distance from a geometric center of the lens, and a bump function. The example method may comprise a step of adjusting the power profile based at least on minimizing a shape metric of a through-focus curve.
