Viewing method and system that promotes a user's eyesight through subliminal changing of viewing parameters

摘要

In a method for displaying visual information (9) on a display surface (3, 13, 20, 21), a display parameter (P) is modified, at trigger intervals, in at least one region of the display surface (3, 13) for a subliminal period of time. The display parameter (P) is preferably selected from the brightness, color, illumination, contrast, focus, frequency or connection/disconnection of the display. By said measure, a viewer of the display surface (3) is prompted to perform a blinking movement which leads to the moistening of the eye with tear fluid and thereby prevents eye irritation without the viewer consciously perceiving the externally controlled blinking.
