Many of us are susceptible to eye strain due to the focus on a computer screen or other interfaces with smaller, detailed items. So when doing these tasks think about preserving your vision with what is called the 20/20/20 rule.
The 20/20/20 rule, if followed, helps reduce fatigue and eye strain. It is pretty simple and states: Every 20 minutes, take at least 20 seconds and look away from your work/screen and focus on something else that is at least 20 feet away from you. Seems like a pretty simple rule but it can be very effective in reducing the strain on your eyes by taking that short break every 20 minutes. In addition it is suggested that you take this little mini-break to do the following to help reduce muscle fatigue throughout your body:
· Get up out of your chair
· Blink your eyes rapidly to propagate tear production
· Stretch your legs and arms
· Walk around if you are able
· Turn your neck and move your shoulders around.
Try this the next time you find yourself spending a lot of time in front of the computer screen. Take a 20 second break every 20 minutes, stretch and look at something else at least 20 feet away.
