Abstract
A projection device for smart glasses. The projection device includes an image-generation unit for generating at least one first ray of light representing first image information, and a second ray of light representing second image information. The first ray of light and the second ray of light differ from each other with regard to a beam divergence. In addition, the first image information and the second image information differ from each other with regard to a perceivable image sharpness. Moreover, the projection device includes at least one deflection element, which is configured to display the first image information within a first field of view of an eye using the first ray of light, and to display the second image information within a second field of view of the eye disposed outside the first field of view, using the second ray of light.
