Plastic lens systems, compositions, and methods

A system for preparing an eyeglass lens, comprising:

• a first mold member having a casting face and a non-casting face;
• a second mold member having a casting face and a non-casting face, the second mold member being spaced apart from the first mold member during use such that the casting faces of the first mold member and the second mold member at least partially define a mold cavity;
• a lens forming composition adapted to be disposed within the mold cavity during use, comprising:
• a monomer composition comprising an aromatic containing polyether polyethylenic functional monomer;
• a co-initiator composition configured to activate curing of the monomer composition to form the eyeglass lens during use;
• and
• a photoinitiator configured to activate the co-initiator composition in response to being exposed to activating light during use;
• a lens curing unit configured to direct activating light and heat toward the mold members during use;
• and
• a coating unit for applying a coating to an eyeglass lens.
