Abstract:
A technology concerning a pair of spectacle lenses for binocular vision. In each of the pair of spectacle lenses for binocular vision, when an inner horizontal direction of each of the spectacle lenses is a direction toward the nose of a user who wears the spectacle lenses, and an outer horizontal direction of the spectacle lenses is a direction toward an ear of the user, a portion for viewing an object at finite distance is provided in each of the pair of spectacle lenses for binocular vision and a shape of a base in prism is formed in the position such that a line of sight of a user viewing an object through the portion is directed to a direction that is different from a direction from the object.
