Ocular lens material

A transparent ocular lens material comprising

• (A) a silicon-containing polymer having a recurring unit represented by the general formula (I):
• ##STR60## wherein each of R.sup.1, R.sup.2, R.sup.3 and R.sup.4 is independently hydrogen atom, an alkyl group having 1 to 5 carbon atoms, an alkoxy group having 1 to 5 carbon atoms or a group represented by the general formula (II):
• ##STR61## in which each of R.sup.5, R.sup.6 and R.sup.7 is independently an alkyl group having 1 to 5 carbon atoms, an alkoxy group having 1 to 5 carbon atoms or phenyl group, and at least one of R.sup.1, R.sup.2, R.sup.3 and R.sup.4 is the group represented by the general formula (II), and
• (B) a condensation polymer having a recurring unit represented by the general formula (III):
