Abstract
A spectacle lens according to the first embodiment of the present disclosure includes: a lens body; and a contrast adjustment section provided on or in the lens body and including a dot-portion group in which dot portions are arranged, wherein the arrangement of the dot portions is non-uniform. A spectacle lens according to the second embodiment of the present disclosure includes: a lens body; and a contrast adjustment section provided on or in the lens body and including a dot-portion group in which dot portions are arranged, wherein the dot-portion group includes dot portions each having an aspect ratio, which is the 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.

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 a first dot-portion group lying in a central area of the lens body, and a second dot-portion group lying in a surrounding area located outside the central area, dot portions in the first dot-portion group are arranged in an isotropic arrangement pattern and dot portions in the second dot-portion group are arranged in a non-uniform arrangement pattern, and
- wherein a comparison between the first dot-portion group and the second dot-portion group results in at least one of:
- (i) the distances between adjacent dot portions in a diametrical direction of the lens body being longer in the second-dot portion group than in the first-dot portion group;
- and (ii) the lengths of the dot portions in the diametrical direction of the lens body being longer in the second-dot portion group than in the first dot-portion group.
