Abstract

A spectacle lens for an imaging optical unit for producing a virtual image of an output image presented on an image generator includes an inner surface facing the eye and an outer surface facing away from the eye, an input coupling section, and an output coupling structure. The imaging beam path is guided to the output coupling structure by way of reflections between the inner surface and the outer surface. A reflection surface having a concave curvature when seen from the interior of the spectacle lens is present between the input coupling section and the output coupling structure in the region of the inner surface and/or in the region of the outer surface. The curvature of said reflection surface differs from a basic curvature of the inner surface or of the outer surface of the spectacle lens.
