PROBLEM TO BE SOLVED: To provide spectacle lenses having satisfactory optical performance even when the spectacle lenses are inserted into a frame of large curvature angles like those of wraparound-type spectacle lenses. SOLUTION: The spectacle lens has an outer surface and inner surface and at least one refraction surface is aspherical surface, wherein the outward normal of the outer surface at a centering and edging point and a prescribed straight line passing the centering and edging point and swiveling center point of the eyeball are inclined and the outward normal and the section of the aspherical surface by a plane inclusive of the prescribed straight line are asymmetric.
