Abstract:
A series of spectacle lenses, where the position of use of the spectacle lenses in front of the eyes of the respective spectacle wearers, nominal variables at the intersection points of first lines of sight are essentially identical to the respective eye-sided or object-sided surfaces of the spectacle lenses. Each first line of sight is a predetermined, eye-sided line of sight, that intersects a pupil center point and an optical eye rotation point of the respective eye. All of the first lines of sight exhibit a predetermined, identical eye-sided visual angle. The nominal variables for each intersection point consist of one or more of a maximum permissible difference between a predefined value of a spherical refractive power and an actual value of a spherical refractive power in the position of use, a maximum permissible difference between a predefined value of an astigmatism and an actual value of an astigmatism in the position of use, a maximum permissible difference between a predefined value of a cylinder axis position and an actual value of a cylinder axis position in the position of use of the respective spectacle lens of the series as well as a method for the production of a spectacle lens.
