ABSTRACT:
Contact lenses formed from compounds of formula I: ##STR1## are disclosed. The compounds are photoinitiators which can be functionalized by means of ethylenic groups or can be bonded to H-active substances, in order, for example, to modify surfaces by means of photopolymerizable substances. The compounds are especially useful in the manufacture of contact lenses.
