ABSTRACT:
The present invention relates to a copolymer for high refractive lens having a refractive index equal to or higher than 1.55, obtained by copolymerization of one or more of the first monomer component having the formula (I) ##STR1## wherein R.sub.1 signifies hydrogen atom or methyl radical, R.sub.2 signifies hydrogen atom or methyl radical, and m and n signify integers 0 to 4 in total, with one or more of the radically polymerizable second monomer component, homo-polymer of which has a refractive index equal to or higher than 1.55 and, if necessary, with the radically polymerizable third monomer component, the homo-polymer of which has a refractive index lower than 1.55 and to the lens prepared from said copolymer.
