Abstract

See full text

A spectacle lens for a display device can be fitted on the head of a user and generate an image. The front side and/or the rear side can be curved. A light guiding channel can guide-light bundles of pixels of the generated image, which are coupled into the spectacle lens via the coupling-in section and coupled out of the spectacle lens via the coupling-out section. The light guiding channel includes a first reflecting surface and a second reflecting surface spaced apart from the first reflecting surface, each of which extend in a direction from the coupling-in section to the coupling-out section. At least one of the two reflecting surfaces can be formed as a switchable layer which can be switched into a first and a second state. The reflectivity of the switchable layer in the first state is higher than in the second state.
