Abstract
Ophthalmic device molds made from a first portion of a molding surface formed from a first polymer and a second portion of the molding surface formed from a second polymer are described. When combined, the first portion and the second portion of the molding surface form an entire molding surface suitable for molding an entire surface, such as an anterior surface or a posterior surface of an ophthalmic device. Methods of manufacturing ophthalmic devices using these molds, including contact lenses, are also described.
