Abstract
A spectacle lens is provided for an image-generating display device that can be fitted on the head of a user, wherein, in order to reduce vignetting occurring when guiding the generated image, which is coupled into the spectacle lens via the coupling-in section and guided through the spectacle lens by means of reflections as far as a coupling-out section, the curvature profile of the front and/or rear side in the edge area differs from the corresponding predetermined curvature profile of the front and/or rear side in the edge area such that there is a greater thickness of the spectacle lens in the edge area in comparison with the thickness in the edge area that would result due to the predetermined curvature profile.
