Abstract: A technology that makes a change in the amount of aberration in a spectacle lens worn by wearer relative to a change in at least one of the aberration in the eye or spectacle lens. A method for designing a spectacle lens wherein, when a degree of change caused by a physical feature of wearer in at least one of an aberration distribution of an eye of wearer and an aberration distribution of a spectacle lens worn by the wearer is large, a spectacle lens that has an aberration distribution of which rotational asymmetry is weak in a region having a predetermined width and a center at any point on a main meridian of the spectacle lens is obtained as a design solution, and when the degree of the change is small, a spectacle lens of which rotational asymmetry is strong in the region is obtained as a design solution.
