Abstract
A spectacle lens for a display device can be fitted on the head of a user and generate an image. The spectacle lens includes a coupling-in section, a coupling-out section, and a light guiding channel. The spectacle lens includes a first partial spectacle lens connected to a second partial spectacle lens. The light guiding channel runs in the first partial spectacle lens and the two partial spectacle lenses are connected to each other via contact surfaces which extend on the one hand from the front side to the rear side and on the other hand from the edge of the spectacle lens along a predetermined length in a second direction, which runs transversely with respect to the first direction.
