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.
