Abstract:
The invention is directed to a method for making a spectacle lens for a non-presbyopic person wherein the spectacle lens is a ready-to-wear lens and has at least one zone having an optical effect to reduce vision stress. In the method, at least one of the following is provided: the contour of the ready-to-wear spectacle lens and one or several visual points whereat the person looks through the ready-to-wear spectacle lens for one or several visual tasks in the near range. This method step is followed by setting at least one of: a design reference point of the zone, the extent of the zone, the optical effect within the zone based on the provided contour, and the visual points. The spectacle lens is then made with this zone.
