The rise in popularity of the iPad and other tablets has led to an increase in people developing computer vision syndrome. Computer vision syndrome (CVS) has many symptoms including eyestrain, headaches, blurred vision and dry eyes. Many people may have the syndrome and not even realize it. Those who spend two more more continuous hours in front of a digital media screen are at the highest risk of developing CVS. The reason for this increased risk is because digital media screens are usually held close to the eyes causing the eyes to strain as they shift in and out of focus to view pixilated images on the screens. In addition, many people don't blink as often as they should when using iPads or tablets which leads to dry and irritated eyes. The American Optometric Association recommends taking a short break every 20 to 30¬† minutes and looking away at a distant object for a few seconds to minimize the risk. Avoiding prolonged work on a tablet and switching to a computer to work for extended periods can also help since computer screens are farther away from the eyes.
