METHOD FOR MANUF ACTURING POLARIZING PLASTIC LENS.

摘要

An embodiment of the present invention pertains to a method for manufacturing a polarizing plastic lens, the method including: an inversion step for inverting the shape of a polarizing film processed to have a curved surface from a convexly curved shape to a concavely curved shape by pressing the film; a forming die assembly step for assembling a forming die having the inverted polarizing film disposed inside a cavity by using the inverted polarizing film, an upper mold, a lower mold and a sealing member for maintaining a s pace between the upper mold and the lower mold; and a polymerization curing step for injecting a curable composition into the cavity and curing the injected curable composition by polymerization to obtain a polarizing plastic lens having the polarizing film disposed in the interior thereof.
