摘要： A computer-implemented method for providing a lens shape for an ophthalmic lens is disclosed. Further, there is provided a method for angular smoothing of a surface determined by carrier lines radially outwards of a prescription zone bordered by a first boundary line. In addition, there is provided an ophthalmic lens, in particular, a spectacle lens. Moreover, a method for minimizing the difference in thickness between two ophthalmic lenses for the same spectacles is provided. A computer program product and a machine-readable storage medium are provided as well.

摘要： 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.

摘要： 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.
