Abstract
The current invention discloses an ophthalmic lens composed of a transparent organic polymer material with a high refractive index and a high Abbe number by copolymerization of a mixture of monomers comprising at least one polythiol monomer and at least one monomer with a high Abbe number comprising two to four bridged cyclic end groups comprising an intracyclic ethylenic double bond or a linear or branched aliphatic residue comprising an ethylenic unsaturation, preferably a vinyl or ethylidene group bonded directly to a carbon of the ring.
