text: In order to achieve an individual optimum of vision comfort for the person , the individual physiology of the person is taken into account in the processing of the retina image, in which: in a first step, a vision impression of the person is determined in a first usage condition, in particular by means of a wavefront error measurement and/or a measurement of subjective refraction, after which, in a second step, a vision impression of the person is determined in a second usage condition, in particular by means of a wavefront error measurement, and after which, in a third step, the wavefront of the person is optimized by determining the correction characteristics for the vision aid until the vision impression of the person in the second usage condition at least approximately matches the vision impression of the person in the first usage condition.
