    摘要： The invention concerns novel polymerisable compositions and optical lenses with high refractive index obtained from said compositions, characterized in that they comprise as constituents base copolymerisable monomers at least 85 wt. % of the total weight of copolymerisable monomers present in the composition: of a mixture M, for 100 parts by weight of the mixture; of (A) 20 to 80 parts of one or several, preferably only one, non-aromatic compounds (I) comprising two thio(meth)acrylate functions, and (B) 80 to 20 parts of a compound of formula (I) in which R1 and R2 represent, independently of each other, H or CH3 and m+n has a mean value from 0 to 20 inclusively; and 3 to 30% by weight relative to the weight of mixture M of a polythiol; the composition containing less than 5 wt. % of other aromatic thio(meth)acrylate copolymerisable, cyclanic or vinyl aromatic mono(meth)acrylate monomers. The invention is applicable to the manufacture of spectacle lenses.
