An eyeglass lens for an optical imaging element for producing a virtual image of an initial image includes a main body and at least one complementary element mounted on the main body. The main body has a material with a first index of refraction n. A viscous or solid intermediate layer is arranged between the complementary element and the main body at least in the region where the complementary element overlaps with a reflection section of the main body. The material of the viscous or solid intermediate layer has a second index of refraction nthat satisfies the condition n<nsin(θ). θis an angle of incidence of the light beams of the imaging beam path proceeding from the incoupling section and incident on the reflection section, selected such that at least 50% of the light beams of the imaging beam path have an angle of incidence of θ>θ.

An optical system for generating a virtual image of a source image provided on an image generator includes a surface of an output coupling that is exposed to a light beam path that is surface-treated such that the light beam path is coupled out from an optical waveguide toward the eye from first partial regions of the surface of the output coupling. In second partial regions of the surface of the output coupling, said second partial regions being different from the first partial regions, said light beam path is coupled out from the optical waveguide toward the eye at most with reduced intensity, or not at all.

A method is provided for the user-specific calibration of a display apparatus, wearable on the head of a user, for an augmented presentation, wherein A), in a basic calibration step, the position of the at least one eye is ascertained relative to the display apparatus in all three spatial directions in the state where the display apparatus is worn on the head of the user and said position is saved in the display apparatus as adjustment data in such a way that an image generating module of the display apparatus generates the image taking account of the adjustment data.

An imaging device includes at least one eyeglass lens to be worn in front of the eye and a display device arranged in the edge region of the eyeglass lens, said display device including an image generator and an imaging optics arranged between the image generator and the eyeglass lens. The image generator is the start point of an imaging beam path which generates the virtual image having an image distance on the basis of the output image and which penetrates into the eyeglass lens by means of the imaging optics via the edge region of the eyeglass lens. An outcoupling device for outcoupling the imaging beam path in the direction of the eye is provided in the eyeglass lens. The display device comprises a device for adjusting the image distance of the virtual image. The invention also relates to data eyeglasses comprising an imaging device.

A spectacle lens for a display device can be fitted on the head of a user and generate an image. The spectacle lens can be constructed with several shells including an outer shell and an inner shell which is joined to the outer shell, wherein a curved channel shell, which includes a curved first reflecting surface and a curved second reflecting surface, is arranged between the outer and inner shell. The light guiding channel includes at least one section of the channel shell and the two reflecting surfaces on which the light bundles are reflected for guiding from the coupling-in section to the coupling-out section.
