Tips to Avoid Computer Eye Strain
Text Size and Color on Your Digital Screen
Text size should be three times larger than the smallest size that you can read from your normal viewing position.
If you use Windows 7, you can adjust text size and color by going to the Start menu, opening the Control Panel and choosing Display. Here you can also adjust your screen's resolution and brightness, for best visual comfort.
Blink more often
Blinking moistens your eyes to prevent dryness and irritation. Ty this exercise: Every 20 minutes, blink 10 times by closing your eyes as if falling asleep (very slowly). This will help rewet your eyes.
Exercise your eyes
Another cause of computer eye strain is focusing fatigue. Look away from your computer at least every 20 minutes and gaze at a distant object (at least 20 feet away) for at least 20 seconds.
Looking far away relaxes the focusing muscle inside the eye to reduce fatigue.
This will reduce your risk of computer eye strain. Also, remember to blink frequently during the exercises to reduce your risk of computer-related dry eye.
Take frequent breaks
To reduce your risk for computer vision syndrome and neck, back and shoulder pain, take frequent breaks during your computer work day.
Eye strain is significantly reduced when take frequent five-minute "mini-breaks" throughout your work day.
Stand up, move about and stretch your arms, legs, back, neck and shoulders to reduce tension and muscle fatigue.
Change your workstation
Improper posture during computer work also contributes to computer vision syndrome. Adjust your workstation and chair to the correct height.
Position your computer screen 20 to 24 inches from your eyes. The center of your screen should be about 10 to 15 degrees below your eyes for comfortable positioning of your head and neck.
