Abstract

To provide a method for producing a thin optical lens molding which is reduced in optical distortion and has excellent stability in surface accuracy. In the method for producing the thin optical lens molding, a molten cyclic olefin based resin is injected from a nozzle of an injection molding machine to be packed in a cavity of molding equipment. A flange part and a lens part are bonded through a recess. The thickness of the flange part is 0.5 mm or below, and the thickness of the recess does not exceed the thickness of the flange part and is 0.4 mm or below. The diameter of the optical lens molding is 10 mm or below. The cyclic olefin based resin is packed so that the maximum value v<SB>max</SB>of the velocity v of the resin in the injection direction of the nozzle is 2,500-20,000 mm/s.
