Working or playing in front of a computer screen may put one at increased risk for eye fatigue and related problems. This is particularly true of children, whose eyes are still developing. All computer users can reduce their risk of eyestrain by remembering to blink more. Studies show that, when sitting in front of the computer, we blink one-third as much as we normally do. The less we blink, the greater risk of dry eye and its attendant problems. Consider adopting the "20-20-20 rule," which calls for taking a 20 second break every 20 minutes, during which time you should sit back and focus on an object 20 feet away. Doing so will also help refresh your mind and body!
