Blink your eyes
Blink count of eyes is 15 per minute. Normally we, computer users while looking at monitor, tend to forget to blink our eyes often (this is due to the concentration on work).
If you don’t blink your eyes in this rate, then eyes become dry and muscles become weaker. While blinking, eyes will get the needed moisture. So, it is very important to blink your eyes at least 15 times a minute.
Suppose you forget to blink your eyes in this rate, and then after every 20 minutes close your eyes completely for 20 seconds (at least) then slowly open your eyes. This will prevent your eyes being restless.
How and where the monitor should be?
Distance: 50 cms should be maintained between your eyes and the monitor.
Location: Centre of monitor should be 8 inches below the eye level.
Illumination: Lower brightness and higher contrast should be set and adjusted according to room lighting so that monitor does not act like a light source. This will avoid eyes being too sensitive to light.
Position: Straight ahead and tilted back 15 degrees.
Avoid light shining directly on your eyes or monitor. Use anti-glare screen. You can use curtains to control the amount of light entering the room.
