Other benefits of the 20 20 20 Rule
The part of the rule that asks you to look at something 20 feet away has other benefits, too! When you look away from your work, you probably stop working, too. This gives the rest of your body a chance to relax as well.
Give this a try and you might experience less fatigue and possibly have more energy at the end of the day–to toss the baseball around with your kids.
What causes eye strain?
Too much time viewing a digital screen makes the eyes work harder, which can lead to eye strain.
When it comes to computers or tablets, it’s the images on the screen. According to the American Optometric Association (AOA), viewing a digital screen puts more demand on the eyes than reading a book or a piece of paper. The eyes work harder because the images may not be as sharp or the contrast might be different when compared to a written page.
Considering how often we use computers and mobile devices both at work and away from work, there is definite risk for headaches, blurry vision, and the other symptoms of eye strain. In fact, according to the AOA, 58 percent of adults in the United States have experienced either digital eye strain or problems with their vision resulting directly from the use of computers and mobile devices.
Other ways to reduce discomfort due to eye strain
The ergonomics of your workstation is another thing to consider to help minimize eye strain. Lighting, monitor placement, keyboard and mouse placement, proper adjustment of your chair, and posture can reduce the risk of injury too. And, not just to your eyes, but to your whole body.
In our Office Ergonomics series, we’ve produced videos to help you optimize your overall workstation set up. Starting with your office chair, view these in the order below for the best results.

Our reliance on computers and digital devices is not going away. To avoid the fatigue and pain that comes with eye strain, we need to give our eyes a break. So remember: every 20 minutes, look at something 20 feet away, for 20 seconds.
