Abstract

Disclosed is a process for producing an ultraviolet radiation absorbing contact lens from a lens shaped polymer having hydroxyl groups pendant therefrom and having dispersed therein a UV absorbing agent substituted with at least one anhydride group which is exposed to basic conditions such that the hydroxyl groups react with the anhydride groups on the UV absorbing agent. As a result the UV absorbing agent becomes fixed to the polymer through the formation of a covalent ester bond.
