PROBLEM TO BE SOLVED: To improve optical performance of transmitting light to be closer to a target optical performance of a progressive refractive power lens, by making an addition being a significant specification in a progressive refractive power lens equal to a value designated in a prescription value, in a progressive refractive power lens included in the progressive refractive power lens series in which an optical effect in wearing a lens and the basic specification of the lens are set so as to be equalized. SOLUTION: In the event that the farsightedness degree S designated in a prescription value is the same, that the astigmatic power C designated in the prescription value is the same, and that the surface addition ADDb (addh) of a reference surface of a second progressive refractive power lens having a large prescription addition add is larger than the surface addition ADDb (addl) of a reference surface of a first progressive refractive power lens having a small prescription addition add; as the prescription addition add increases, the value is set so as to decrease in which a difference between the surface additions ADDc (addh) and ADDc (addl) of a correction surface M2 is standardized by a difference between the wearing additions addh and addl.
