Abstract: A spectacle lens design system capable of suppressing deformation during finishing processing. The system (LDS100) is designed for a spectacle lens, wherein the spectacle lens design system comprises: a prescription data acquisition part 110 to acquire prescription data which includes prescribed power information, and designated lens thickness information relating to finishing processing information regarding finishing processing after shaping of a spectacle lens; an optical surface calculation part 122 to calculate an optical surface shape based on the prescribed power information of the prescription data, thereby generating optical surface shape data; an appropriate lens thickness information generation part 124 to generate appropriate lens thickness information regarding a lens thickness appropriate for performing the finishing processing, based on the finishing processing information of the prescription data; and a thickness calculation and shape adjustment part 127 to adjust lens shape data based on the optical surface shape data and the lens thickness information.
