Abstract: An eyeglass lens with a functional region, wherein the functional region includes: a base region that causes a luminous flux that has entered an object-side face to exit from an eyeball-side face, enter a pupil of a wearer, and converge on a retina; and retinal non-convergence regions that cause a luminous flux that has entered the object-side face to exit from the eyeball-side face, and do not cause a luminous flux that has entered the pupil of the wearer to converge on the retina, at least some of the retinal non-convergence regions are buffer regions that can compensate local negative astigmatism occurring due to spherical aberration of the eye at some positions of a distribution of the astigmatism, and surfaces of the buffer regions are toric surfaces whose axial direction is a circumferential direction, and are elongated along the circumferential direction in a plan view.

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.
