Abstract
Spectacle lenses that allow a wearer to view an object in a more comfortable manner include a pair of lenses for the left and right eyes. The power of one of the pair of lenses is shifted toward the positive side with respect to the power of the other lens, and object-side average surface power (base curve) of the one lens is smaller than object-side average surface power (base curve) of the other lens. The power (dioptric power) is principal meridian power along a principal meridian of each of the lenses, and the base curve is in the direction along the principal meridian.
