    • The present invention relates to new polymer compositions for use in the manufacture of opthalmic lenses which result from the copolymerization of a component (A) comprising at least 50% by weight of a monomer or mixture having formula ##STR1## wherein R.sub.1 and R.sub.2 are selected from H and C.sub.1 -C.sub.6 alkyl radical,X is --O--, --S--, --SO.sub.2, --CO--, --CH.sub.2 --, --CH.dbd.CH--, or C(CH.sub.3).sub.2,m and n are integers and m+n ranging from 0 to 10 and 0,5 to 15% by weight of a component (B) comprising a monomer having an ethylenic unsaturation which does not contribute to an aromatic system and having a free hydroxy group in position .alpha. of the unsaturation, as well as to their use in opthalmology and to apparatus using these lenses, such as eyepieces and film/video camera optics.
    • 本发明涉及用于制造眼用透镜的新型聚合物组合物,其由包含至少50重量%的具有式(I)+ TR(I))的单体或混合物的组分(A) 其中R1和R2选自H和C1-C6烷基,X是-O - , - S - , - SO2,-CO-,-CH2 - , - CH = CH-或C(CH3)2 ,m和n为整数,m + n为0至10,0.5至15重量%的组分(B),其包含不对芳族体系有贡献且具有游离羟基的具有烯属不饱和度的单体 在不饱和位置的α位,以及它们在眼科学中的使用以及使用这些透镜的装置,例如目镜和胶片/摄像机光学元件。
