Abstract
According to the invention, the eye of the subject is lit with light from the non-visible spectrum (infrared light) in such a way that its image, taken with an infrared camera, is of sufficiently high-contrast for an evaluation, so that the actual line of sight can be calculated from the picture based on the characteristics of the eye and that, proceeding from the determined line of sight, the coordinates of the coming optical stimulation can be adjusted in such a way that the intended retinal area is stimulated.
