An eyeglass lens, comprising: a hidden mark defining a predetermined reference point; and refractive portions arranged along a meridian extending substantially in a vertical direction via the predetermined reference point, and wherein the refractive portions comprises: a first refractive portion located on a lower side of the predetermined reference point and having a first refractive power; a second refractive portion located on an upper side of the predetermined reference point and having a second refractive power smaller than the first refractive power; and an intermediate refractive portion in which refractive power continuously decreases, and an aberration distribution in the first refractive portion is substantially symmetrical in a left and right direction with respect to the meridian extending in the vertical direction, and an aberration distribution in the second refractive portion is asymmetrical in the left and right direction with respect to the meridian shifted to an ear side. |
