Abstract

This disclosure includes methods and systems for producing ophthalmic lenses. Some methods include identifying a plurality of zones within a spatial representation of a lens blank, selecting, for each of the zones, one or more parameters for producing the lens, and producing the lens by removing material from the lens blank according to the one or more parameters of each of the zones.
