To easily manufacture a spectacle lens corresponding to a user's individual condition.

In order to fulfill all individual requirements of a spectacle prescription comprising spherical effect, astigmatic effect, and/or prismatic effect and their effect distribution along an x axis and a y axis of a spectacles lens, a rear face of the spectacle lens is made a multi-focal surface, without point symmetry or axial symmetry so that all are satisfied by a prescription side of the spectacle lens. A front surface has a convex spherical surface or a rotational symmetry aspherical shape. About a semi-product selected from semi-products having a limited number (about 10) of different front radiuses, processing is performed while talking into consideration user's individual pupil interval so as to provide a progressive multi-focal surface that does not have point symmetry nor axial symmetry on the rear face and so as to fulfill the individual requirements, and the spectacle lens attaining all of individually required dioptric effect is manufactured.
