Abstract
A mold assembly for casting optical lenses in which an integral lens blank-mold cup unit is created by placing liquid monomers in a cup mold which tightly adheres to polymerized lens material. A radial die is disposed upon the cup mold to contain the monomers during polymerization and to provide the polymerized material with an optical surface. A contact lens is manufactured from the integral lens blank-mold cup unit by machining off the first cup and then extraneous portions of the blank to create a finished lens.
