Patent ID: 7944637

Claim:
A method for manufacturing a polarizing resin lens, comprising steps of: preparing a lens base and a polarizing film molding; applying an ultraviolet adhesive on the rear surface of the polarizing film molding to form an ultraviolet adhesive layer; superimposing the front surface of the lens base on the ultraviolet adhesive layer and bonding by an ultraviolet irradiation to form a laminated lens substrate; filling a curing resin monomer on a molding die; mounting the laminated lens substrate on the curing resin monomer to superimpose the polarizing film molding of the laminated lens substrate on the curing resin monomer to form a curing resin monomer layer on the polarizing film molding of the laminated lens substrate; and curing the curing resin monomer layer to bond and integrate the curing resin monomer layer and the laminated lens substrate; further comprising steps of: trimming the outer periphery of the polarizing film molding of the laminated lens substrate around the ultraviolet adhesive layer got out of the lens base to leave a projecting portion; and when mounting the laminated lens substrate on the molding die, laying the projecting portion of the laminated lens substrate on a step portion formed on the inner circumference of a frame of the molding die to hold a distance between a concave surface of the molding die and the polarizing film molding of the laminated lens substrate.
