Abstract

The present invention encompasses, in part, a method and apparatus for lens casting in which two molds (20 and 40), preferably formed of plastic, are interconnected or joined together via a ring (50) to form a mold cavity (60) having substantially the same dimensions of the lens to be formed therein. The invention is further directed to compositions and methods used in lens casting. In a first implementation the invention includes a mold (10) having a ring (50) having an interior periphery (54), a front mold (20) formed of a plastic and having a lens-forming surface (22), an edge (28) circumscribing the lens-forming surface that is sized to be complementarily received within a portion of the interior periphery of the ring, and a base (30) having dimensions greater than the interior periphery, and a rear mold (40) formed of a plastic having a lens-forming surface (42).
