Abstract
A target design is produced with a computer-implemented method that takes into consideration an astigmatic effect and is suitable for optimizing a spectacle lens having the astigmatic effect. The method includes providing an initial target design that does not directly take into consideration the astigmatic effect of the spectacle lens, and producing the target design by correcting the initial target design on the basis of a correction target design that directly takes into consideration the astigmatic effect of the spectacle lens.
