Computer Vision Syndrome – Causes and Treatment

Do you work on computers for long hours? You may have what is known as Computer Vision Syndrome (CVS). Go through the following list of symptoms to find out:

Eye Symptoms

Heaviness of eyes, burning, stingy or foreign body sensation, redness, double vision (diplopia), inability to focus on the computer monitor and blurred vision even after you have finished working on computer.

Other Symptoms

Headache, neck pain (because of abnormal posture), dizziness and even sleepiness.
CVS is very common. About 90% of those who work on computers for more than 3 hours every day have some symptoms of CVS.

The odds are higher if you are directly under a fan or in front of an air conditioner. Also, a bright computer screen makes you more prone to develop CVS especially if the light in the surrounding is dimmer.

CVS like symptoms are also experienced by those who do a lot of near work especially if it requires prolonged concentration.

How to Treat and Prevent Computer Vision Syndrome

1. Reduce the brightness of your computer’s screen.

2. Change the position of your work table away from the fan and/or air conditioner. Alternatively get the fan or AC relocated away from your work table.

3. Blink frequently. We tend to blink less frequently when we concentrate on something. Blinking is important because it keeps your eyes moistened with the natural tear film. Less frequent blinking causes dryness of eye surface which is responsible for a variety of symptoms associated with CVS.

4. Follow the 20-20-20 rule. After every 20 minutes, look away from the computer screen at a distance of 20 feet (or more) for at least 20 seconds. This simple exercise relaxes some muscles in your eyes which are responsible for focusing on near objects like your phone, a book or your computer screen. When you follow 20-20-20 rule, you give rest to those muscles.

5. Bonus tip: Follow ‘Modified 20-20-20 Rule’. After every 20 minutes of work, get up from your seat; walk around for at least 20 seconds while looking at a distance of 20 feet. You will not only prevent computer vision syndrome, but also other lifestyle diseases.

6. Consult your doctor. Get your eyes checked. You may need glasses. If you have a refractive error, you may confuse your symptoms with CVS. This is also applicable to many other eye diseases which may mimic computer vision syndrome. Also, if your doctor makes the diagnosis of CVS, you may be prescribed some medical treatment in addition of lifestyle changes.

If you follow the advice above, you’ll be among those 10% who don’t have any symptoms of CVS even after working on computers for long duration. Just be proactive.
