METHOD OF MANUFACTURING PLASTIC LENS

摘要

PROBLEM TO BE SOLVED: To provide a high quality plastic lens that can be used to make glasses show an excellent sense of wearing.

SOLUTION: A method for manufacturing the plastic lens contains: injecting plastic lens raw material liquid to the forming die cavity; performing curing reaction of plastic lens raw material liquid in the cavity and obtaining the plastic lens base material having a transferred surface where a mold forming surface shape is transcribed; releasing the plastic lens base material from a forming die; and annealing the plastic lens base material after the release. At least one of two molds that compose the forming die is a round mold, the cavity is a non circular in the plane view shape in the cross section and, as a result, the transferred surface of the plastic lens base material obtained by the curing reaction in the cavity becomes a non circular. The annealing is performed in the state where the round mold forming surface held on the mounting table and the transferred surface of the plastic lens base material are adhered and arranged.
