Abstract:
An eyeglass lens made by the method comprising:placing a liquid lens forming composition in a mold cavity defined by at least a first 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)pâ€”CH2]kâ€”R2 where m and p 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 where A1 has the general structure where each R1, is independently an alkyl containing from 1 to 4 carbon atoms, phenyl, or a halogen; each (a) is independently between 0 and 4; each Q is independently oxy, sulfonyl, alkanediyl having from 2 to 4 carbon atoms, or alkylidene having from 1 to 4 carbon atoms; and n is between 0 to 3; and 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 the lens forming composition to cure the lens forming composition to form the eyeglass lens.
