What is the 20-20-20 rule

It's a handy tool you can use at work or at home to reduce eye fatigue.

Being surrounded by screens - from laptops to desktops to cell phones, TVs and tablets - our eyes are experiencing more screen time than any time in history, and it’s taking a toll.

Designed to reduce eye fatigue, the 20-20-20 rule says that every 20 minutes of screen time, you should look away at something at least 20 feet away for at least 20 seconds.

These regular screen breaks give your eyes some much-needed rest and help prevent eye strain.
