Abstract
A progressive spectacle lens includes an upper viewing zone with a distance reference point providing a first refractive power, in particular a first mean refractive power, adapted to distance vision; a lower viewing zone with a near reference point providing a second refractive power, in particular the second mean refractive power, adapted to near vision, the second refractive power, in particular the second mean refractive power, representing an addition power relative to the first refractive power, in particular the first mean refractive power; a corridor between the upper viewing zone and the lower viewing zone in which the refractive power gradually changes from the first refractive power, in particular the first mean refractive power, to the second refractive power, in particular the second mean refractive power; and a left peripheral zone and a right peripheral zone, which are separated by the corridor and the lower viewing zone.
