METHOD FOR MANUFACTURING FUNCTIONAL PLASTIC LENS AND POLARIZING PLASTIC LENS

WIPO Patent Application WO/2016/157909

A1

When manufacturing a functional plastic lens by filling a functional sheet S, for which precision of bending processing is different according to direction, into a mold 50and insert molding a lens main body integrally with the functional sheet S, a method for manufacturing a functional plastic lens according to the present invention fills the functional sheet S into the mold 50 such that, letting the direction wherein the bending processing precision for the functional sheet S is high be a reference axis A, the resin filling direction and the reference axis A are not orthogonal. Thus, a high quality functional plastic lens is provided.
