Abstract:
A progressive spectacle lens, a method for its production, and a related computer program are disclosed. The progressive spectacle lens has a progressive surface including a central viewing zone, a lower viewing zone, two peripheral vision zones extending bilaterally from a vertical meridian of the progressive surface, and an upper viewing zone. The central viewing zone has a surface power providing a first refracting power for distance vision and the lower viewing zone has a greater surface power than the central viewing zone providing a second refracting power corresponding to near vision and being connected to the central viewing zone by a first progressing power region. The progressive spectacle lens generates a retarding or arresting effect on myopia progression, especially in myopic juveniles.
