FIELD: ophthalmic devices.

SUBSTANCE: invention relates to an ophthalmic device, which is a free radical reaction product of a reaction mixture containing: one or more monomers suitable for the manufacture of an ophthalmic device and a polymerisable high-energy radiation absorbing compound of formula III, where m and n are independently equal to 0, 1, 2, 3, or 4; X represents O, S, NR, SO or SO₂; Y is a linking group; P_g is a polymerisable group; R at each occurrence is independently represented by H, C₁-C₆ alkyl, cycloalkyl, heterocycloalkyl, aryl, heteroaryl, or YP_g; and R¹ and R², if present, at each occurrence are independently represented by C₁-C₆ alkyl, C₁-C₆ alkoxy, C₁-C₆ thioalkyl, C₃-C₇ cycloalkyl, aryl, halogen, hydroxy, amino, NR³R⁴ or benzyl, while R³ and R⁴ are independently represented by H or C₁-C₆ alkyl, or two adjacent R¹ or R² groups together with the carbon atoms to which they are attached form a cycloalkyl or aryl ring. Also described is a method for manufacturing an ophthalmic device, including the polymerization of a mixture containing compounds of formula III.

EFFECT: absorption of various wavelengths of ultraviolet radiation and/or high-energy radiation of the blue part of the visible spectrum.
