PURPOSE:To reduce the mandays of the assembly of the components of a plastic lens. CONSTITUTION:A plastic lens 1a and a plastic holding member 2 holding the plastic lens 1a can be assembled and joined in a molding die in plastic lens components. Consequently, the mandays of assembly can be shortened largely, and the effect of the reduction of manufacturing cost is displayed. A plastic molding process, a lens-barrel molding process and these assembly process can be performed by the same process, the adhesion of fouling, the intrusion of foreign matters, etc., can be prevented, and fouling generated in the assembly process and the generation of foreign matters can be diminished. |
