Abstract:
A method for making a plastic eyeglass lens, comprising:placing a liquid lens forming composition in a mold cavity defined by at least a first mold member and a second mold member, the lens forming composition comprising: a monomer composition comprising an aromatic containing polyethylenic polyether functional monomer having the general structure: R2â€”[CH2â€”(CH2)mâ€”O]jâ€”A1â€”[Oâ€”(CH2)nâ€”CH2]kâ€”R2 â€ƒwhere m and n are each independently 1 or 2; where j and k are each independently between 1 and 20; R2 is vinyl, allyl, methacrylyl, acrylyl, methacrylate, or acrylate; and A1 is a dihydroxy aromatic-containing material; a photoinitiator configured to initiate polymerization of the monomer composition in response to being exposed to activating light during use; and directing activating light toward at least one of the mold members to cure the lens forming composition to form the eyeglass lens.
