Abstract

A projection device for smart glasses. The projection device includes an image generating unit for generating at least one first light beam representing image information, and at least one deflecting element, which is configured to deflect the first light beam in the form of a second light beam representing first image information, and to deflect the first light beam in the form of a third light beam representing second image information, into a first field of vision and/or into a second field of vision of an eye; the second light beam and the third light beam differing with regard to a beam divergence; and the second field of vision and the first field of vision at least overlapping.
