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 curved front and/or side, wherein a light guiding channel which is suitable for guiding light bundles of pixels of the generated image, which are coupled into the spectacle lens via the coupling-in section of the spectacle lens, in the spectacle lens to the coupling-out section to couple them out of the spectacle lens via the coupling-out section. The coupling-out section includes at least two deflecting surfaces arranged next to each other which reflect the light bundles in the direction of the rear side for the coupling out. Deflecting surfaces can be formed as a switchable layer which can be switched into a first and a second state, wherein the reflectivity of the switchable layers in the first state is higher than in the second state.
