Abstract
A method and system for producing a first spectacle lens for a specific situation of wear for correcting at least a first astigmatic refraction of a first eye of a wearer, which has a first cylinder reference axis αin a reference direction of sight −eof the first eye. According to the method and apparatus, a primary direction of sight −eof the first eye for at least one primary evaluation point iof the first spectacle lens is determined and a corresponding primary direction of sight −eof a second eye of the spectacle wearer that corresponds to the primary direction of sight −eof the first eye in the specific situation of wear is also determined. Furthermore, a first primary merit function for at least one surface of the first spectacle lens is minimized, in which the first primary merit function for the at least one primary evaluation point iof the first spectacle lens takes into account a correction of a first primary transformed astigmatic refraction by the first spectacle lens in the specific situation of wear such that the first primary transformed astigmatic refraction depends on the corresponding primary direction of sight −eof the second eye.
