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 optical article, such as a spectacle lens, includes, on a substrate, a photochromic layer containing a photochromic dye and a resin component, and a protective film. The indentation hardness of the photochromic layer in the thickness direction is less than or equal to the indentation hardness of the surface of the substrate. The result of multiplying the indentation hardness of the protective film in the thickness direction and the thickness of the protective film is five-hundredths or more times and one or less times the result of multiplying the indentation hardness of the photochromic layer in the thickness direction and the thickness of the photochromic layer.
