Provided is a spectacle lens (1) belonging to a series of spectacle lenses having each of first refractive power and second refractive power in common, where a progressive region length, which is a length along a meridian (LL') within a progressive region (AP), is shorter than a predetermined reference spectacle lens belonging to the series of spectacle lenses, and a designed maximum differential value where a normalized addition refractive power distribution in the progressive region (AP) is differentiated is caused to be close to a reference maximum differential value where a normalized addition refractive power distribution in the progressive region (AP) of the reference spectacle lens is differentiated. |
