Abstract
A resin composition for use in a hybrid lens containing a radical polymerizable monomer and a silane coupling agent. A specified di(meth)acrylate compound and a specified mono(meth)acrylate compound are used preferably as the radical polymerizable monomer. A hybrid lens molding die in which a glass lens base material and a glass mold of transferring an aspherical shape are opposed to each other is used, a resin composition for use in the hybrid lens is filled between them and UV-rays are irradiated from both sides of the glass lens base material and the glass mold to manufacture a hybrid lens in which the resin layer is bonded on the glass lens base material. A high performance hybrid lens having a resin layer of large thickness, with a large localized thickness and capable of increasing the aspherical quantity can be manufactured by the method.
