Eyeglass lens design system, eyeglass lens design method, and eyeglass lens design program

摘要

PROBLEM TO BE SOLVED: To provide a spectacle lens design system capable of designing an optical surface shape at an early stage. A spectacle lens design system 100 for designing a spectacle lens whose optical surface includes a progressive surface is designed by designing and designing a spectacle lens with a prescription data acquisition unit 110 for acquiring prescription data and an optical surface as a spherical surface. The optical surface including the progressive surface is calculated based on the appropriate lens thickness information generation unit 122 that generates the appropriate lens thickness information so that the thickness of the spectacle lens is satisfied with the predetermined condition, and the prescription data and the appropriate thickness information. It also includes an optical surface calculation unit 123 that generates optical surface information. [Selection diagram] Fig. 3
