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 progressive addition lens includes: a near portion for viewing a near distance, a distance portion for viewing a distance farther than the near distance, and an intermediate portion between the near portion and the distance portion and having a progressive refraction function. A transmission astigmatism is added to at least the near portion and the intermediate portion, and in the near portion and the intermediate portion to which the transmission astigmatism is added, after subtracting the refractive power for astigmatism correction, the progressive addition lens further includes a portion where the amount of vertical refractive power is greater than the amount of horizontal refractive power.
