PROBLEM TO BE SOLVED: To obtain plastic lens molded products having different eccentric amounts by using a single mold. SOLUTION: Since an eccentric amount can be regulated by a ring member, at least a pair of cores are constituted of a core 1 having a recess surface 1a and a core 2 having a protrusion surface 2a and a ring member 4 for relatively eccentrically deviating central axes of the surfaces 1a and 2a is arranged on an outer periphery of one of the pair of the cores 1, 2. Resin is injected in a cavity 3 formed between the surfaces 1 and 2a, and injection molded to obtain the eccentric lens. |
