Eye strain is caused by prolonged use of our screens. These could be large or small screens. They all emit rays that can damage the eyes over time. Prolonged screen time should be avoided by young and old alike.

This is the reason for the 20-20-20 rule.

What is the 20-20-20 rule?

This simple rule suggests that for every 20 minutes of screen time, you should look away at something at least 20 feet away for at least 20 seconds. This helps you reduce eye fatigue and prevent eye strain.

While there has been little scientific research to test the effectiveness of this rule, some studies have shown results that indicate fewer symptoms of computer vision syndrome, a reduction in dry eyes, and relaxation of the eye muscles which may relieve eye strain.

How to use it

One way to use this rule effectively is to have a 20-minute timer set once you start working with your screen. When it goes off, practice looking 20 feet away while counting to 20. Then reset the timer and continue working for another 20 minutes. You can look further than 20 feet away as well. Aim for longer distances, rather than shorter ones.

There are apps you can download that help one practice the 20-20-20 method. Check your app store for them.

Other methods to reduce eye strain

There are other methods to help you reduce eye strain.

By using these methods, you can maintain healthy vision and reduce your risk of developing eye problems.

If you’re experiencing eye strain or other symptoms of computer vision syndrome, be sure to talk to your eye doctor. They can help diagnose the problem and recommend appropriate treatment.
