A method of forming an ophthalmic lens using a composite ophthalmic lens vacuum mold to quickly and inexpensively produce, on-site, multi-focal, prescription and non-prescription optical quality eyeglasses, with or without photochromic, and photochromic non-prescription (e.g., sunglasses, safety glasses, reading glasses, etc.) optical quality eyeglass via a vacuum remolding. The method further includes a rigid remolding process for forming the composite ophthalmic lens.

[ What is claimed is:] [1.]1. A composite ophthalmic lens vacuum mold for forming an ophthalmic lens therein comprising:a stage having alignment means for aligning a base tool and a stage opening;a base tool seated on said stage and having an upper side and a lower side, said upper side being a concave seat and having a central opening defining a passage through the base tool, said lower side having alignment means in engagement with said base tool, said base tool passage being aligned with said stage opening;a light housing having a light source;a generally flexible mold having an upper side and a lower side, said upper side having a recess for receiving an amount of a polymerizable composition thereon and said flexible mold lower side being heated and seated within said base tool upper side;a stock lens, the stock lens being positioned on said polymerizable composition when placed within said recess of said flexible mold; anda vacuum motor having an elongated vacuum tube projecting outwardly therefrom and sized for engaging said stage opening and said passage, said vacuum motor capable of creating a suction force through the vacuum tube for pulling the heated flexible mold against the base tool upper surface and thereby deforming the flexible mold, wherein said light source is capable of emitting radiation at a frequency and for a duration to polymerize said polymerizable composition, thereby causing said polymerizable composition to be laminated on the stock lens to form a composite ophthalmic lens while said flexible mold is suctioned against the base tool.
