Fortunately, there is no evidence that eyestrain caused by computers results in permanent vision damage. People are spending more and more time in front of computers at home, work and school. Some factors that lead to eyestrain are unavoidable like the normal deterioration of vision that begins around age 40. Other factors that lead to eyestrain may easily be avoided. Avoid eyestrain and keep eyes moist and relaxed by blinking.
Studies show that people blink less often when working at computers.
Small typeface, improper background colors and monitor contrast also cause eyestrain. To reverse the effects of eyestrain, adapt your work environment to your body posture instead of adapting your body posture to your work environment. It should be four to eight inches lower than eye level. Position the monitor as if it were a book or magazine, so that the eyes look slightly down towards it. Large-screen monitors with a higher pixel count and higher refresh rate prevent eyestrain.
