Abstract

PURPOSE:To obtain a titled lens of which resin layers are uniformly thick and do not peel by integrally forming hydrophilic resin layers on the surfaces of a base material for the plastic lens. CONSTITUTION:The inside surface sides of glass molds 2, 2' are coated with hydrophilic high polymer layers 5, 5 (shown by solid black) in an imperfectly set state (unreacted monomer is contained and the degree of polymn. has progressed on the side near surfaces of the glass molds 2, 2'). Next, the above-mentioned glass molds 2, 2' and a gasket 1 are combined, and a monomer for the base material for the plastic lens is poured into the space thus formed, after which the assembly is heated or is irradiated with ultraviolet rays to allow polymn. to complete, whereby the antifogging lens of the three-layered structure integrated with the hydrophilic resin layers on the lens surfaces is obtained. For example, 2-hydroxyethyl methacrylate is used for the monomer constituting the above-mentioned hydrophilic resin layers, and, for example, diethylene glycol bis-allyl carbonate is used for the high polymer monomer for the base material for the lens.
