More than 50 percent of computer users experience eyestrain, headaches, blurred vision and other visual symptoms related to sustained use of the computer. This type of stress on the visual system can also cause body fatigue and reduced efficiency at work. In addition, there are now indications that heavy computer users are at risk for glaucoma.
This is the most important thing you can do to prevent or treat computer vision problems. According to the National Institute of Occupational Safety and Health (NIOSH), computer users should have an eye exam before they start working on a computer and once a year thereafter. Be sure to tell your eye doctor how often you use a computer at work and at home.
The symptoms will doubtless be recognisable to many of you: sore, tired, burning eyes, blurred vision, headache, after images when you look away for the monitor, light sensitivity and dry eyes. The frustration is that however much your eyes are suffering, stopping work and giving your eyes a sustained rest might not be an option, particularly if you’re doing something important that relies on using a computer.
Take eye breaks. Throughout the day, give your eyes a break by forcing them to focus on something other than on your screen. Try the following exercise: Hold a finger a few inches in front of your face; focus on the finger as you slowly move it away; focus on something far in the distance and then back to the finger; slowly bring the finger back toward your face. Next, shift your focus to something farther than eight feet away and hold your eyes there for a few seconds. Repeat this exercise three times, several times a day.
Take rest breaks at least every 20 minutes to allow eyes and muscles to recuperate. Short, frequent breaks are better than longer, less frequent breaks. Try 2-3 minutes every 15-20 minutes, 5 minutes every 30 minutes, or 10 minutes every hour.
When you already have eye strain, relieving it can be a simple process. Look to a different distance. Your eyes have two sets of muscles that keep your lens in focus. When one set of muscles is tired, stretch and relax them by using the other set. So if you are tired from reading, for example, stare off into the distance for a few minutes.
This practice relaxes the optic nerves and helps improve eyesight. Holding your head straight look to your right, and hold the position for about 5 seconds. Repeat the movement looking to your left, looking up, and down.
Practice relaxation. Ease muscle tension with this relaxation exercise: Place your elbows on your desk, palms facing up; let your weight fall forward and your head fall into your hands; position your head so that your eyebrows rest on the base of your palms, with your fingers extended toward your forehead; close your eyes and take a deep breath through your nose; hold it for four seconds, then exhale. Continue this deep breathing for 15 to 30 seconds. Perform this simple exercise several times a day.
