Abstract:
An optical element, used as first imaging element, includes a first entry surface and a curved exit surface. A spectacle lens, used as second imaging element, includes a curved second entry surface and a coupling-out section spaced apart therefrom. An imaging optical system images the generated image as a virtual image by guiding the light bundles fed to the optical element via the first entry surface to the curved exit surface, and coupling them from the latter, via the curved second entry surface, into the spectacle lens, in which they are guided to the coupling-out section and coupled out via the coupling-out section to generate the virtual image. To reduce the lateral chromatic aberration in the imaging of the virtual image, the two imaging elements are produced from different materials; one having positive refractive power and the other having negative refractive power for imaging the virtual image.

Claim (Index 19):
The imaging optical system according to  claim 16 , wherein the light bundles coupled into the spectacle lens are guided in the spectacle lens to the coupling-out section by at least one of at least one reflection and at least one total internal reflection.
