Abstract

Adjustment of an eyeglass lens or a pair of eyeglasses by means of an individual brightness-dependent centering of an eyeglass lens. In particular, a method for adjusting an individual eyeglass lens for at least one eye of an eyeglass wearer, including: defining an individual usage situation which comprises at least one target brightness value for the light to be captured by the at least one eye; determining a position of the pupil in at least one direction of view of the at least one eye which occurs or is expected at the at least one target brightness value; determining a reference point of the eyeglass lens, in which the eyeglass lens effects a required correction of individual refraction data for the at least one direction of view; on the basis of the determined individual value of the pupil position, providing and arranging the eyeglass lens in such a manner that the at least one reference point of the eyeglass lens is arranged in front of the at least one eye of the eyeglass wearer.
