Abstract: A pair of right and left spectacle lenses each includes: a distance vision region and a near vision region; and a progressive region in which a refractive power progressively changes between the distance vision region and the near vision region. In the pair of right and left spectacle lenses mounted in a spectacle frame, a height position of a distance eye point that is a reference point of the distance vision region is different between right and left, and a corridor length connecting the distance vision region and the near vision region is different between right and left.
