Is the 20 20 Rule Real?

As we spend more time staring at screens, it’s not uncommon to experience eye strain. The 20-20-20 rule is a simple and effective way to prevent this problem. This rule suggests that for every 20 minutes spent looking at a screen, we should take a 20-second break and look at something 20 feet away. But is this rule real? Let’s find out.

The Science Behind the 20-20-20 Rule

According to optometrists, our eyes are not designed to stare at screens for long periods. The blue light emitted by screens can cause eye strain, headaches, and even disrupt our sleep patterns. The 20-20-20 rule helps to prevent eye strain by reducing the amount of time we spend looking at screens without a break.

When we look at something far away, our eyes relax and adjust to a different focal length. This break allows our eye muscles to rest and reduces the strain on our eyes. The 20-20-20 rule is a simple way to remember to take frequent breaks and prevent eye strain.

How to Implement the 20-20-20 Rule

Implementing the 20-20-20 rule is easy. All you need to do is set a timer for 20 minutes and take a 20-second break every time it goes off. During this break, look at something 20 feet away. This could be a picture on the wall, a tree outside, or anything that’s far enough to give your eyes a break.
