ABSTRACT:
Monomeric polysiloxanes end-capped with activated unsaturated groups polymerized with a comonomer comprising a polycyclic ester of acrylic acid or methacrylic acid to form a soft contact lens is disclosed. These instant polysiloxane copolymer contact lenses have unexpectedly high tear strengths and unexpectedly high modulus of elasticity.
