What’s the 20-20-20 rule?

Basically, every 20 minutes spent using a screen; you should try to look away at something that is 20 feet away from you for a total of 20 seconds.

How can you tell if something is 20 feet away?

Consider looking out a window at an object that seems far away, like a tree or a building across the street. If you work in a small space, try walking outdoors or into a larger area where you can rest your eyes.

Why 20 seconds?

It takes about 20 seconds for your eyes to completely relax.

While you’re resting your eyes, it’s also a good idea to get up and grab a drink of water to keep yourself hydrated. If your body is hydrated, your eyes will be as well.

Drinking green tea during your break may help even more. That’s because green tea contains antioxidants called catechins that may help your eyes produce tears for better lubrication.

What about reminding yourself to do this every 20 minutes?

You probably get absorbed in reading or work when you’re looking at screens. Setting a timed reminder to pop up can help you take a break every 20 minutes. There are also free apps like Eye Care 20 20 20 or Donald Korb Blink Training that can help. Just click start when you begin your screen time, and the app will remind you to take a break.

Digital Eye strain can be a troublesome issue for many specially nowadays because of the increased dependency on the screens.
