PCT No. PCT/EP94/02595 Sec. 371 Date Apr. 11, 1996 Sec. 102(e) Date Apr. 11, 1996 PCT Filed Aug. 5, 1994 PCT Pub. No. WO95/06266 PCT Pub. Date Mar. 2, 1995The present invention relates to ophthalmic lenses with a refractive index from 1.50 to 1.51, which are the cured product of compositions comprising 60-99% wt % of at least one poly(allyl carbonate) of a polyhydroxy alcohol, said polyhydroxy alcohol having from 2 to 20 carbon atoms and from 2 to 6 hydroxy groups in the molecule, less than comonomers, and 0.01 to 10 wt % of a radical initiator. These ophthalmic lenses have the advantages of improved tintability and a low rejection rate in their production due to the reduction in prerelease during polymerization casting. Preferably, the ophthalmic lenses and the use of diallyl phthalate type oligomers in ophthalmic lenses. |
