A method of manufacturing plastic photochromic lenses characterized by comprising the steps of: obtaining a lens by polymerizing and curing a monomer mixture comprising at least (1), (2), and (3) below; directing radiation comprising ultraviolet radiation of a wavelength of less than or equal to 300 nm onto at least a portion of the surface of the lens obtained; coating a composition comprising (4) and (5) below onto the surface of the lens that has been exposed to said radiation; and curing said coating to obtain a hard surface film: (1) a monofunctional or bifunctional methacrylic ester monomer comprising 50 weight percent or more of the monomer mixture; (2) a trifunctional or greater methacrylic ester monomer comprising 1 to 30 weight percent or more of the monomer mixture; (3) one or more photochromic dyes; (4) an organic silicon compound comprising an alkoxy group and an epoxy group; and (5) a colloidal metal oxide. A plastic photochromic lens obtained by the above manufacturing method.
