An injection molding device includes a male mold portion and a female mold portion mating with the male mold portion. The male mold portion includes a first molding surface defined therein. The female mold portion includes a through hole, an ejector sleeve received in the through hole and having a cavity hole, and a cavity insert received in the cavity hole of the ejector sleeve and having a second molding surface facing upwardly the first molding surface. An axis of the cavity hole is spaced from that of the through hole. If an eccentricity is presented on the molded lens, the cavity insert can be rotated to adjust the relative location of the first and second molding surface such that the eccentricity of the molded lens can be adjusted.
