| 摘要 |
<p>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.</p> |
