Abstract: In an eyeglass lens, an edge adjustment between an incoupling segment and an outcoupling structure can be provided by shaping of the inner surface. In the region of the eyeglass lens through which the eye looks for straight-ahead viewing, the inner surface substantially has a curvature that approximates the curvature of a typical inner surface of an eyeglass lens to such an extent that no perceptible optical imaging errors are induced by the inner surface when straight-ahead viewing. In the region of the edge adjustment, the inner surface has a shape that deviates to a greater extent from the curvature of the typical inner surface, which shape enables an imaging beam path coupled into the eyeglass lens by the incoupling segment to be directed to the outcoupling structure by reflections between the inner surface and the outer surface of the eyeglass lens.

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.

To reduce the lateral chromatic aberration in the imaging of the virtual image, the two imaging elements are produced from different materials; one having positive refractive power and the other having negative refractive power for imaging the virtual image.
