PROBLEM TO BE SOLVED: To provide spectacle lens that satisfies individual needs of wearers upon viewing an intermediate distance.;SOLUTION: A spectacle lens design method is the spectacle lens design method that includes: a first refractive part that has refractive power corresponding to a far distance or middle distance; a second refractive part that has refractive power corresponding a near distance; and an intermediate part that is provided between the first refractive part and the second refractive part, and successively connects the refractive power from the first refractive part to the second refractive part. In the spectacle lens, the spectacle lens is designed so that on the basis of a first parameter for determining a position of the spectacle lens corresponding to a viewing line direction when a wearer views an object present at an intermediate distance between the far distance or middle distance and the near distance, and a second parameter for determining add power to be added at the position thereof, the add power is added at the position thereof.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
