Many of us spend a great deal of time looking at the computer screen. This can put a lot of strain on our eyes causing eye fatigue. Spending long hours looking at the computer, mobile, or tablet screens can put the strain on eyes. Using the rule of 20-20-20 can help in preventing the problem.
What exactly is 20-20-20 rule?
If you find yourself gazing at the screen for so long, your doctor might have mentioned The rule of 20-20-20 was designed by Californian optometrist Jeffrey Anshel. It is an easy reminder to take breaks from long working hours of looking at the screen every 20 minutes. When following a rule, what you have to do is take a break every 20 seconds from looking at the screen after every 20 minutes. During that break, you have to relax the eye muscles by focussing on an object 20 feet away.
- Firstly, set an alarm after every 20 minutes while working as a reminder to take a break from your work.
- You can also download the apps that are developed to help people follow the rule of 20-20-20.
- Look out for a window during the 20-second breaks. Judging a distance of 20 feet can be a bit difficult, but you can focus on the street or lamppost. It would work just well.
A person can benefit from closing their eyes for 20 seconds every 20 minutes so as to get relief from the constant gaze at the computer screen. Also, remember to blink. It can also prevent dry eye by encouraging the production of tears. If you are sitting in your chair for too long, you might also suffer from back problems. So, if you want to avoid neck pain or back problems, get up and walk around for good 5 minutes.
Why only 20 seconds?
The reason why we have mentioned only 20 seconds is that it takes only 20 seconds for your eyes to completely relax. While you’re resting your eyes, it is also a great idea to get up and grab a drink of water to keep yourself hydrated. You can also drink green tea that will help you even more. Green tea contains catechin which is an antioxidant that may help your eyes produce more and better lubrication.

Is there any evidence that supports the rule?
