Lighting
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.
Working Habits
Long exposures to computer screens may cause eye strain. Symptoms include headache,
burning eyes, blurred vision and discomfort. To minimize eye strain, computer users can
adjust working habits to let their eyes relax and recover.

Break Times
Computer users should take some time away from the screen especially if working for
prolong hours. Generally, it is recommended to take short breaks (5 – 15 mins) after 1 –
2 hours of continuous computer works. Taking short and frequent breaks is more
advised than longer breaks.

Looking at Distant Objects
Users often blink less when in front of monitor screen. To minimize eye strain and
dryness, users should rest the eye periodically by focusing on objects that are far away.
