An optical system includes a light guide to be worn in front of one eye, which guides light beams from the source image into the light guide and towards a reflective outcoupling arrangement, which couples the light beams out of the light guide to the eye. The outcoupling arrangement has a plurality of individual mirrors, which are spaced apart from one another in the light propagation direction. A first group of individual mirrors couples first light beams, which originate from a first imaging region, out of the light guide towards the eye, and at least one second group of individual mirrors couples second light beams, which originate from a second imaging region, out of the light guide towards the eye. The individual mirrors of the first group and the second group are each arranged alternating in the light propagation direction.

An optical system for transmitting a source image includes a light guide, which defines a light transmission channel, an optical coupling arrangement and an optical decoupling arrangement, the coupling arrangement being designed to couple light emerging from the source image into the light guide arrangement in such a way that the light can propagate in the light guide arrangement by total reflection, and the decoupling arrangement being designed to decouple light that has propagated in the light guide arrangement from the light guide arrangement. The light guide arrangement comprises an optical deflection device, which, as viewed in the direction of propagation of the light in the light guide arrangement, is arranged between the coupling arrangement and the decoupling arrangement and is designed to deflect light ray bundles, emerging from the coupling arrangement at different beam angles and impinging divergently on the deflection device, in bundled manner towards the decoupling arrangement.

In an eyeglass lens, an edge adjustment between an incoupling segment and an outcoupling structure can be provided by shaping of the inner surface. In the region of the eyeglass lens through which the eye looks for straight-ahead viewing, the inner surface substantially has a curvature that approximates the curvature of a typical inner surface of an eyeglass lens to such an extent that no perceptible optical imaging errors are induced by the inner surface when straight-ahead viewing. In the region of the edge adjustment, the inner surface has a shape that deviates to a greater extent from the curvature of the typical inner surface, which shape enables an imaging beam path coupled into the eyeglass lens by the incoupling segment to be directed to the outcoupling structure by reflections between the inner surface and the outer surface of the eyeglass lens.

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.
