Optimization and production of a spectacle lens for a specific wearing situation for correcting at least one astigmatic refraction of an eye of a spectacles wearer, which in a reference viewing direction of the eye has a cylinder reference value and a cylinder reference axis, comprising: specifying an object distance for at least one evaluation point of the spectacle lens; determining a transformed astigmatic refraction for the at least one evaluation point of the spectacle lens from the cylinder reference value and the cylinder reference axis depending on the specified object distance; and optimizing the spectacle lens such that for the at least one evaluation point a correction of the transformed astigmatic refraction by the spectacle lens in the specific wearing situation is taken into consideration, wherein determining the transformed astigmatic refraction comprises determining a transformed cylinder value and/or a transformed cylinder axis depending on the specified object distance.
