Adequate lighting is necessary to avoid glare and eye fatigue. Excessive or insufficient lighting
makes the display on screen harder to see. Generally, lighting level should not exceed 750 lux and
levels ranging from 300 to 500 lux are most appropriate for computer desk work. Recommended
lighting arrangement includes positioning work stations away from direct sunlight or using
overhead lighting with baffles or louvers that reduces glare.
