Monomeric polysiloxanes end-capped with activated unsaturated groups polymerized with acrylic acid and a comonomer comprising a polycyclic ester of acrylic acid or methacrylic acid to form a hydrophilic, water absorbing contact lens is disclosed. These polysiloxane polymer contact lenses are unexpectedly capable upon hydration of retaining from 1 percent to about 99 percent by weight of water, based upon the total weight of the dry, i.e., unhydrated polymer. |
