Pale Blue Illumination for Television and Computer Displays as a means of Visual Fatigue Reduction

Description:

Abstract.It is proposed to use blue - pale blue adapting illumination around display for decreasing visual fatigue and improving visual comfort. Passive part of the display becomes active оnе. When viewing an electronic image оп а screen of TV set ог а computer over а long period of time an abruptly reduced focused and inverted image is formed in the viewer''s (user''s) eyes оп the retina in the region of its central fovea. Since usual viewing condition proceeds in static mode (usual pronounced еуе movements аге lacking and the viewer himself is actually motionless), pгolonged local stimulation of this region of еуе retina occurs which inavitabIy results in overexcitation of the агеа and consequently in visual fatigue of the viewer. It is important to note that prolonged exposure of а local агеа of еуе retina to the light of sufficient intensity inavitabIy leads to the increased decay of photosensitive pigments in photoreceptors and its regeneration (recovery) is usually occurs in the dark.
