Abstract:
An eyeglass lens made by the method comprising:placing a liquid polymerizable lens forming composition in a mold cavity defined by at least a first mold member and a second mold member; wherein the liquid polymerizable lens forming composition comprises:a photoinitiator;an aromatic containing bis(allyl carbonate)-functional monomer; anda polyethylenic-functional monomer containing at least two ethylenically unsaturated groups selected from acrylyl and methacrylyl;directing first ultraviolet rays toward at least one of the mold members to cure the lens forming composition so that it forms a lens with a back face, edges, and a front face;applying a mold member of the mold cavity to a substantially solid conductive heat source; andconductively applying heat to a face of the lens by (a) conductively transferring heat to a face of a mold member from the conductive heat source, and (b) conductively transferring heat through such mold member to the face of the lens.
