OPTICAL RESIN LENS AND METHOD FOR PRODUCING OPTICAL RESIN MATERIAL

摘要

Disclosed is an optical resin lens with high durability whose optical characteristics do not deteriorate even when it is irradiated with a laser or other optical energy for a long time. Also disclosed is a method for producing an optical resin material. The optical resin lens is characterized by comprising a polymer which is obtained by a production process including a step for polymerizing an olefin using a catalyst composed of a titanium halide and an organic aluminum represented by the general formula: RnAlX3-n (wherein n satisfies 1 < n <= 2, R represents a hydrocarbon group, and X represents a halogen atom).
