8. A spectacle lens comprising:
a lens body; and
a contrast adjustment section provided on or in the lens body and comprising a dot-portion group in which dot portions are arranged,
wherein the dot-portion group comprises dot portions each having an aspect ratio, which is a ratio of the length in the short-axis direction to the length in the long-axis direction in the plan-view shape, of less than 1,
