The invention relates to the use of an optical visual aid (6) with at least one spectacle lens (10) of an observer (28) for viewing an object (15). The optical visual aid (6) has for at least one viewing direction (A, B) a dioptric power that is adjusted for one eye (11, 11') of the observer (28) and is made up of multiple dioptric power components (Κ1, K2, K3, K4). According to the invention, a first dioptric power component (K1, K3) of the multiple dioptric power components (K1, K2, K3, K4) has a corrective effect that is the best possible for the eye (11, 11') of the observer at a defined distance As of the object (15) from the corneal vertex of the eye (11, 11') for the viewing direction (2, 4). At the same time, a further dioptric power component (K2, K4) of the multiple dioptric power components (K1, K2, K3, K4) has, for the viewing direction, an additional astigmatic, partially corrective effect for the eye (11, 11') of the observer at the defined distance As. The invention also relates to a method for determining a sought parameterization of the visual aid (6) that is suitable for the specified use and also to a system for determining a sought parameterization of such a visual aid (6).
