    Abstract: A spectacle lens can inhibit ametropia of the eyes and ensure full visibility. The spectacle lens comprises: first refraction areas and second refraction areas. Each first refraction area has a first refraction force that may be based on a prescription for correcting the ametropia of the eyes. Each second refraction area has a refraction force different from the first refraction force and may function to focus images on the positions except the retina of the eyes, to inhibit the development of the ametropia. Near the central part of the lens, the second refraction areas form a plurality of independent island-shaped areas, and the first refraction areas form the areas beyond the areas of the second refraction areas.

    Abstract: An electronic element for electronic light control spectacles, which is combined with a lens and exhibits a light control effect when electric energy is supplied, including substrates, a pair of transparent electrode layers provided on the substrates, and a light control layer provided between the pair of transparent electrode layers, a sealing material that covers at least a part of the transparent electrode layer is provided in a peripheral area outside a light control area in which the pair of transparent electrode layers and the light control layer overlap, and each of the pair of transparent electrode layers has a projecting part extending to the peripheral area, and the projecting part is in contact with the sealing material without other conductive members being interposed therebetween.

    Abstract: With regard to an eyeglass lens that is provided with a plurality of defocus regions on at least one of an object-side surface and an eyeball-side surface, the surface shape is evaluated through measuring the surface shape of the surface of the eyeglass lens that has the plurality of defocus regions, and acquiring three-dimensional data regarding the surface shape; a classifying data groups regarding the plurality of respective defocus regions and a data group regarding a base region, which is a region where the defocus regions are not formed, by performing cluster analysis on the three-dimensional data; combining curved surface shape data obtained by performing curve fitting on each of the classified data groups, and extracting reference shape data regarding the object-side surface; and comparing the three-dimensional data and the reference shape data, and obtaining degrees of deviation of the three-dimensional data from the reference shape data.

    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.
