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.

First claim

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 arrangement of the dot portions is non-uniform.

2 . The spectacle lens according to claim 1 , 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, and wherein compared to the first dot-portion group, (i) the distances between adjacent dot portions in the diametrical direction of the lens body are longer in the second dot-portion group.

3 . The spectacle lens according to claim 2 , wherein the arrangement of the dot portions of the second dot-portion group corresponds to an arrangement in which dot portions in predetermined positions of the arrangement of the dot portions of the first dot-portion group have been moved in the diametrical direction of the lens body.

4 . The spectacle lens according to claim 2 , wherein the dot-portion group further comprises a third dot-portion group lying in an intermediate area located between the central area and the surrounding area, and wherein in the third dot-portion group, the distance between dot portions in the diametrical direction of the lens body is intermediate between the corresponding distance between dot portions in the first dot-portion group and the corresponding distance between dot portions in the second dot-portion group.

5 . The spectacle lens according to claim 1 , 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.

6 . 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 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.

7 . The spectacle lens according to claim 6 , 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, and wherein compared to the first dot-portion group, (ii) the lengths of dot portions in the diametrical direction of the lens body are longer in the second dot-portion group.

8 . The spectacle lens according to claim 7 , wherein the second dot-portion group includes pairs of dot portions coupled together, and wherein each dot-portion pair forms a coupled dot portion whose length in the diametrical direction of the lens body is longer than the corresponding length of each of the dot portions constituting the dot-portion pair.

9 . The spectacle lens according to claim 7 , wherein the second dot-portion group includes inclined dot portions which each have, at the periphery, an inclined portion whose thickness decreases outwardly in the diametrical direction of the lens body, and which each have a length which is longer than the corresponding length of each dot portion of the first dot-portion group in the diametrical direction of the lens body.

10 . The spectacle lens according to claim 7 , wherein the dot-portion group further comprises a third dot-portion group lying in an intermediate area located between the central area and the surrounding area, and wherein in the third dot-portion group, the length of each dot portion in the diametrical direction of the lens body is intermediate between the corresponding length of each dot portion of the first dot-portion group and the corresponding length of each dot portion of the second dot-portion group.

11 . The spectacle lens according to claim 7 , wherein compared to the first dot-portion group, (i) the distances between adjacent dot portions in the diametrical direction of the lens body are longer in the second dot-portion group.

12 . The spectacle lens according to claim 1 , wherein the dot-portion group comprises a first arrangement and a second arrangement which differ in the arrangement of dot portions in the diametrical direction of the lens body, and which are located at different positions in the circumferential direction of the lens body.

13 . The spectacle lens according to claim 1 , wherein the dot portions are recessed portions formed in the contrast adjustment section.

14 . The spectacle lens according to claim 6 , wherein the dot-portion group comprises a first arrangement and a second arrangement which differ in the arrangement of dot portions in the diametrical direction of the lens body, and which are located at different positions in the circumferential direction of the lens body.

15 . The spectacle lens according to claim 6 , wherein the dot portions are recessed portions formed in the contrast adjustment section.
