    • 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 α0(1) in a reference direction of sight −ez(1) of the first eye. According to the method and apparatus, a primary direction of sight −eζ(1,p) of the first eye for at least one primary evaluation point ib(1,p) of the first spectacle lens is determined and a corresponding primary direction of sight −eζ,k(2,p) of a second eye of the spectacle wearer that corresponds to the primary direction of sight −eζ(1,p) of 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 ib(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 −eζ,k(2,p) of the second eye.
    • 一种用于制造用于特定磨损情况的第一眼镜镜片的方法和系统,用于校正在参考方向上具有第一气缸参考轴线α0(1)的佩戴者的第一眼睛的至少第一散光折射, ez(1)的第一只眼睛。 根据该方法和装置,确定第一眼镜的至少一个初级评估点ib(1,p)的第一只眼睛的主要视向(1,p),并且相应的主要方向 还确定了在特定磨损情况下与眼睛佩戴者的第二只眼睛相对应的第一只眼睛的主要方向(1,p)的第一只眼睛的-ezeta,k(2,p)。 此外,用于第一眼镜镜片的至少一个表面的第一主要功能函数被最小化,其中第一眼镜镜片的至少一个初级评价点ib(1,p)的第一主要功能函数考虑到 在特定的磨损情况下校正由第一眼镜透镜进行的第一次主变换的散光折射,使得第一初级变换的散光折射取决于第二眼的对应的主要方向-ezeta k(2,p)。
