Have you ever heard myth that says: Computers do not harm your eyes. ? Well, the fact is computers are the number 1 cause of eyestrain in the United States. If you spend hours per day in front of computer, you should be aware of this kind of computer fatigue.

Back in 1999, OSHA stated that “Computer vision syndrome (CVS), defined as a complex of eye and vision problems that are experienced during and related to computer use, is a repetitive strain disorder that appears to be growing rapidly, with some studies estimating that 90 percent of the 70 million U.S. workers using computers for more than 3 hours per day experience it (CVS) in some form.”

If you’re experiencing two or more of the following symptoms daily, you can be pretty sure you’re struggling with computer eye strain, not just the ordinary eye fatigue.

Symptoms:

* Eyestrain
* Blurred vision
* Dizziness or nausea
* Difficulty concentrating
* Headaches
* Red, dry or burning eyes
* Increase in nearsightedness
* Change in color perception
* Slow refocusing
* Excessive fatigue
* Neck, shoulder and back pain
* Eye-teaming problems and/or occasional double vision

To prevent computer eye strain, make sure there are enough light in the room, and try to remember these three Rs:

1. Readjust
   Your eyes should be looking down, not up
2. Refocus
   Stare at something far every now and then
3. Remove
   Yup, remove yourself.. your entire body from the computer once in a while

In addition, you could also do some exercise at your computer desk, try the following tips:

• Rotate your head from side to side slowly, looking up and down, and looking left and right, and hold in each position for 30 seconds
• Interlace your fingers behind your head and press your elbows toward the wall behind you.
• Slowly bend your head down and up, looking down at your chest, then up to the ceiling. (hold for 30 seconds)
