A spectacle lens for a display device can be fitted on the head of a user and generate an image. A spectacle lens body includes a front side and/or the rear side that are curved, and at least a first and a second partial body, the mutually facing boundary surfaces of which are in direct contact, and as seen in top view onto the spectacle lens, a coupling-in section in an edge area of the spectacle lens and a coupling-out section in a central area of the spectacle lens. The spectacle lens can guide light bundles of pixels of the generated image to the coupling-out section and couple them out of the spectacle lens via the coupling-out section. A flat first reflecting surface and a flat second reflecting surface spaced apart from the first reflecting surface are provided in the spectacle lens body.

An imaging optical unit for generating a virtual image of an initial image represented on an image generator includes at least one spectacle lens, an input coupling device for coupling an imaging beam path emanating from the initial image in between the inner surface and the outer surface of the spectacle lens, and a Fresnel structure present in the spectacle lens for coupling the imaging beam path out from the spectacle lens in the direction of the eye. The input coupling device couples the imaging beam path in between the inner surface and the outer surface of the spectacle lens in such a way that it is guided by reflections between the inner surface and the outer surface to the Fresnel structure. The Fresnel structure has Fresnel surfaces, which bring about a base deflection of the rays of the imaging beam path by 45 to 55 degrees.

Disclosed is a coupling device for coupling the imaging beam path between the inner surface and the outer surface of the eyeglass lens; and a decoupling structure-present in the eyeglass lens for decoupling the imaging beam path from the eyeglass lens in the direction of the eye. The coupling device couples the imaging beam path between the inner surface and the outer surface of the eyeglass lens such that the imaging beam path is guided to the decoupling structure via reflections between the inner surface and the outer surface. A beam-splitting structure is present between the display device and the area of the eyeglass lens, in which the first reflections occurs, said beam-splitting structure splitting the imaging beam path extending from the image generator into two partial imaging beam paths, which form the beam paths arriving from different directions on the partial structures of the decoupling structure.

A spectacle lens for a display device that can be fitted on the head of a user and generate an image guides 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 by reflections on the rear side and a reflecting surface lying opposite this to the coupling-out section and coupling them out of the spectacle lens via the coupling-out section. A splitter layer reflects a portion of light bundles reflected by the rear side towards the rear side and transmits a portion, wherein after reflection on the rear side the reflected portion strikes the splitter layer again and there, once again, is partially reflected towards the rear side and partially transmitted. The transmitted portions strike the facets are coupled out of the spectacle lens through the splitter layer and the rear side.

A spectacle lens for a display device can be fitted on the head of a user and generate an image. The spectacle lens body can include a front side, a rear side, a coupling-in section in an edge area of the spectacle lens and a coupling-out section in a central area of the spectacle lens, two opposing reflecting surfaces in the area of the coupling-in section, and facets embedded in the area of the coupling-in section in the spectacle lens body between the two reflecting surfaces and arranged next to each other in the direction from the coupling-in to the coupling-out section in a first and an adjoining second area. The facets in the first area can be partially reflective or reflective. The facets in the second area can be partially reflective. Directly neighboring facets in the second area can be connected by a partially transparent or wholly transparent face.

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 front side and a rear side, a coupling-in section and a coupling-out section spaced apart from the coupling-in section, as well as 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, by which they are coupled out of the spectacle lens. The light guiding channel includes a first reflecting layer, which extends from the coupling-in section to the coupling-out section and on which the light bundles are reflected for guiding to the coupling-out section. The first reflecting layer includes at least one transparent gap.

A spectacle lens for a display device that can be fitted on the head of a user and generate an image. A coupling-in section in an edge area of the spectacle lens and a coupling-out section in a central area of the spectacle lens. The spectacle lens is suitable for coupling light bundles of pixels of the generated image into the spectacle lens via the coupling-in section, guiding them in the spectacle lens to the coupling-out section and coupling them out of the spectacle lens via the coupling-out section. The coupling-in section can divide at least one of the light bundles into several first sub-bundles and couple them into the spectacle lens offset from each other in a first direction such that the first sub-bundles are guided in the spectacle lens to the coupling-out section along a second direction running transverse with respect to the first direction.

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.

A first side of the outer shell of a spectacle lens faces away from the inner shell and forms the front side of the spectacle lens, and the first side of the inner shell faces away from the outer shell and forms the rear side of the spectacle lens. The outer shell includes the coupling-in section, the light guiding channel and the coupling-out section. The inner shell includes an opening which extends from the second side of the inner shell, which faces towards the outer shell, in the direction of the rear side and in which the light guiding channel sits. The coupling-out section lies next to the opening such that the light bundles coupled out by the coupling-out section enter the inner shell via the second side of the inner shell, run through the inner shell and leave the inner shell via the rear side.
