1. A spectacle lens for an image-generating display device that can be fitted on the head of a user, comprising:
a curved front side and a curved rear side, and, when the spectacle lens is viewed from above, with a coupling-in section in an edge area of the spectacle lens and a coupling-out section spaced apart therefrom, wherein the spectacle lens is configured to couple the generated image into the spectacle lens via the coupling-in section of the spectacle lens, and to guide the generated image in the spectacle lens by reflection as far as the coupling-out section and to couple the generated image out of the spectacle lens via the coupling-out section, wherein the spectacle lens provides a predetermined optical imaging function which is predefined by a predetermined curvature profile of the front side and a predetermined curvature profile of the rear side, and wherein, in order to reduce vignetting occurring when the generated image is guided via the coupling-in section through the spectacle lens as far as the coupling-out section, the curvature profile of at least one of the front and rear sides in the edge area differs from the corresponding predetermined curvature profile of the front and rear sides 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. |
