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: A technology concerns a spectacle lens to suppress unnecessary convergence. In the spectacle lens, when an inner horizontal direction of the spectacle lens is a direction toward the nose of a user who wears the spectacle lens, and an outer horizontal direction of the spectacle lens is a direction toward an ear of the user, a shape of a base in prism is formed in a portion in which power continuously changes and through which a main line of sight, influenced by convergence of the user of the spectacle lens, passes such that at least a part of a base out prism, which may be generated in the portion, is cancelled.
