Expert says it is important to take breaks and blink regularly while working on computer as most of them suffer from the symptoms of Computer Vision Syndrome (CVS). A recent study suggested that prolonged sitting at desk may increase risk of heart disease, stroke and diabetes.

As 70% computer users suffer from the symptoms of Computer Vision Syndrome (CVS), it is crucial to take few measures to protect your health. Symptoms of CVS are eye strain, headaches, red eyes, double vision besides difficulty refocusing the eyes.

The London Vision Clinic professor Dan Reinstein said, "When we use a computer for long periods, we only blink around 4 - 7 times per minute. Our usual rate of blinking is more like 18 - 20 times per minute, so this is a significant reduction - it can cause symptoms such as dry eyes and blurred vision.”
