Computer vision syndrome, also called digital eye strain, is caused by the use of computers, cell phones and E-readers for extended periods of time. The greater the amount of time you spend using digital screens, the worse the level of your discomfort.
The symptoms of computer vision syndrome (CVS) are eyestrain, a bad headache, neck and shoulder pain and eye dryness. These symptoms are a result of bad lighting, improper viewing distances, and poor posture. You can treat it by applying the 20-20-20 rule. Every 20 minutes, try to look at something that is 20 feet away for 20 seconds.
