Abstract

PURPOSE:To manufacture a contact lens with high oxygen and water permeability, superior fittingness and superior adaptability to a living body by using a copolymer of hydroxyalkyl methacrylate with collagen. CONSTITUTION:To a monomer mixture consisting of hydroxyalkyl methacrylate and 0.007-1.3wt% collagen is added <=49wt% water, and they are polymerized by heating in the presence of a polymn. initiator in a contact lens molding container to obtain a contact lens with superior optical properties, superior tensile strength and a high coefft. of oxygen permeability. In case of the correction of eyesight, especially high ametropia, the thickness of the lens can be made relatively small, the lens has a great affinity for tears and corneal structure, and it can be fitted continuously over a long time.
