Abstract

A method for molding a resin optical lens and the optical lens made thereby includes following steps: Grains of resin are heated to a temperature PHT1 to a softened state. A mold formed by a lower and an upper die, and a chamber formed there between is controlled to form clean dry area, and its surfaces are heated to a molding temperature PHT2 greater than PHT1. The softened resin is put in the lower die. The upper and lower die are clamped and heated and pressurized so that resin melts and tills the chamber. The mold is cooled to set the molten resin as an optical lens. The dies are separated and the optical lens is removed. The lens has an improved reliability of full refractivity. There is no need to provide a sprue for the shaping mold, improving the utilization of the resin material and reducing manufacturing cost
