Abstract
An apparatus and method for partially curing a polymerizable monomer or monomer mixture to form a soft contact lens includes a transport device for transporting a plurality of contact lens molds to a precure station in a low oxygen environment, each contact lens mold including a first and second mold half with a polymerizable monomer or monomer mixture therebetween. A clamping member having a plurality of mold engagement members clamps a first contact lens mold half against a second contact lens mold half for a predetermined pressure and time. While the mold halves of the contact lens mold are clamped, the polymerizable monomer or monomer mixture is exposed to a radiant energy source for polymerizing the polymerizable monomer or monomer mixture contained in each contact lens mold.
