Abstract
Disclosed is a coupling device for coupling the imaging beam path between the inner surface and the outer surface of the eyeglass lens; and a decoupling structure-present in the eyeglass lens for decoupling the imaging beam path from the eyeglass lens in the direction of the eye. The coupling device couples the imaging beam path between the inner surface and the outer surface of the eyeglass lens such that the imaging beam path is guided to the decoupling structure via reflections between the inner surface and the outer surface. A beam-splitting structure is present between the display device and the area of the eyeglass lens, in which the first reflections occurs, said beam-splitting structure splitting the imaging beam path extending from the image generator into two partial imaging beam paths, which form the beam paths arriving from different directions on the partial structures of the decoupling structure.
