    Abstract: The invention concerns an ophthalmic lens made of a transparent organic polymer with high refractive index and high Abbe number. The material constituting the lens is obtained by polymerisation of a mixture of monomers comprising: at least a polythiol monomer; and at least a monomer with high Abbe number comprising two to four cross-linked cyclic terminal groups including an intracyclic ethylene double bond or a vinyl group or ethylidene directly bound to the cycle carbon atom. The invention is applicable to spectacle lenses.

    Abstract: The invention concerns a polymerisable composition with high refractive index and high Abbe number. Said composition of polymerisable monomers comprises: (A) at least a polythio(meth)acrylate monomer; (B) at least a monomer with high Abbe number comprising at least 2 polymerisable groups, and at least one cross-linked polycyclic constitutive unit, the cross-linked polycyclic constitutive unit(s) not being directly bound to the oxygen atom; (C) at least a polythiol monomer; and optionally (D) at least another monomer copolymerisable with (A), (B) and (C); the composition being free of all monomers comprising one or several vinyl functional groups, other than (meth)acrylic or thio(meth)acrylic groups, and different from monomers (B).

    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.
