MANUFACTURING METHOD OF PLASTIC LENS

摘要

PROBLEM TO BE SOLVED: To provide a manufacturing method of a plastic lens which can sharply reduce defect caused by the generation of optical strain or striae and which can also prevent the remarkable prolongation of a curing time. SOLUTION: The manufacturing method of the plastic lens is provided which has a step of pouring a plastic lens raw material 20 into a lens mold 16 for molding the lens and a step of curing the plastic lens raw material 20. In the curing step, the lens mold 16 is forcibly moved regularly or irregularly by a driving device 30. The generation of the optical strain can be suppressed even in the case of a thick plastic lens. COPYRIGHT: (C)2008,JPO&INPIT
