Abstract

This invention has the objective of providing polymers for ophthalmic lenses having high oxygen permeability and superior surface wettability. It relates to a method for the manufacture of polymers for ophthalmic lenses characterized in that the polymers are formed by reacting a polymer comprising, as a polymerization component, at least one monomer (a) having organosiloxane groups and a polymerizable group having a carbon-carbon unsaturated bond with a hydrophilic component (b).
