    摘要： PROBLEM TO BE SOLVED: To provide an efficient design method of a progressive refractive power lens that takes into consideration not only optical performance but also exterior appearance performance.SOLUTION: The design method of the progressive refractive power lens includes a step S030 of determining an addition power of an entire lens serving as a sum of an addition power of a lens outer surface and an addition power of a lens inner surface; and a step S040 of determining the addition power of the lens outer surface. In the step S040 of determining the addition power of the lens outer surface, when exterior appearance performance of the lens is prioritized more than optical performance thereof, the design method is configured to determine the addition power of the lens outer surface so that the addition power of the lens outer surface is 0 or more and smaller than the addition power of the entire lens, and when optical performance of the lens is prioritized more than the exterior appearance performance thereof, the design method is configured to determine the addition power of the lens outer surface so that the addition power of the lens outer surface is larger than the addition power of the entire lens.

    摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing a die for a mold or the like which retains fundamental design data, and is suitable for preventing the deterioration of an optical property as an eyeglass lens.SOLUTION: In a method of manufacturing a die for a mold, design data of a formed surface are created based on predetermined prescribed information, the formed surface is generated in accordance with the design data. Error amounts to a design value by the design data are specified on respective first and second corresponding points corresponding to respective first and second reference points defined on the generated formed surface. A first corrected surface is defined based on the error amount on the first corresponding point. A second corrected surface which does not have refractive power at the first corresponding point is defined based on the first corrected surface and the error amount on the second corresponding point. The design surface by the design data, the first corrected surface and the second corrected surface are synthesized, the design data are corrected based on the synthesized data after the synthesis, and the formed surface is generated in accordance with the corrected design data.
