ABSTRACT:
A composite optical article has a plastic layer of an outer diameter less than the outer diameter of a lens base member. The plastic layer is formed on the base member so as to expose an optical surface thereof and has a projecting outer periphery. Another composite optical article has a lens base member having formed therein or thereon an annular projection or groove to which an outer periphery of a plastic layer formed on the base member is bonded. The composite optical articles are manufactured by a method in which an annular projection or groove is formed on or in a plastic layer molding surface of a mold or the lens base member along an outer periphery thereof and the plastic layer is molded while filling the plastic material along the projection or groove.
