Abstract
The present invention provides an eyeglass lens and its related techniques, the eyeglass lens including: a base region that causes a light flux that has entered from an object-side face to exit from an eyeball-side face, and to enter an eye and converge at a position A on a retina; and a plurality of defocus regions that are in contact with the base region, in which a light flux that passes through at least part of each defocus region is incident on the position A as diverging light, wherein a refractive power in the defocus regions increases in a direction from a center portion to a peripheral portion.
