Abstract
A system and method of forming surfaces on eyeglass lenses is described. In some examples, the surface is a spherical, cylindrical or spherocylindrical surface at a center of the lens and an aspherical surface at a periphery of the lens. In some examples, forming the surface on the lens reduces the thickness of the lens at the periphery of the lens.
