Abstract

A spectacle lens for a display device may include a front side, a rear side, a coupling-in section and a coupling-out section. The coupling-out section includes at least two reflective deflecting surfaces arranged next to each other. The spectacle lens guides light bundles of pixels of the generated image to the coupling-out section in the spectacle lens and couples them out of the spectacle lens through the rear side. The spectacle lens includes a main part with the front and rear side, in which a recess extending from the rear side or from the front side to the surface structure is present, into which an insert element is inserted, the first end of which facing the surface structure is formed complementary to the surface structure, wherein the reflective deflecting surfaces lie between the surface structure of the main part and the first end of the insert element.
