There is provided a progressive addition lens for spectacles including a distance portion and a near portion having different powers, wherein an equivalent spherical power of the distance portion is plus; and a first lens and a second lens having different addition powers from each other, and a difference between vertical surface power OVPf1 in the distance portion and vertical surface power OVPn1 in the near portion on an object-side surface of the first lens, and a difference between vertical surface power OVPf2 in the distance portion and vertical surface power OVPn2 in the near portion on an object-side surface of the second lens are the same. |
