Patent ID: 8506076

Claim:
A method 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 in a reference direction of sight −e z (1) of the first eye has a first cylinder reference axis α 0 (1) , the method comprising: determining a primary direction of sight −e ζ (1,p) of the first eye for at least one primary evaluation point i b (1,p) of the first spectacle lens; determining a primary direction of sight −e ζ,k (2,p) of a second eye of the wearer that corresponds to the primary direction of sight −e ζ (1,p) of the first eye in the specific situation of wear; and minimizing a first primary merit function to produce at least one surface of the first spectacle lens, wherein the first primary merit function for the at least one primary evaluation point i b (1,p) of 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 −e ζ,k (2,p) of the second eye.
