Abstract (en)
[origin: WO2009115718A2] A series of progressive ophthalmic lenses is proposed, which is indexed by optical power addition values of glasses of spectacles to be made from these lenses. Each lens of the series determines a further gap between a value of the optical power for the near vision direction and a maximum value of the optical power which is obtained for a direction of gaze pointing below said near vision direction. The lenses of the series are adapted for postures of wearers that may vary as a function of the optical power addition values.
