Look20: 20-20-20 Eye Break

Long screen days? Look20 reminds you every 20 minutes to look 20 feet away for 20 seconds — a small habit to ease eye strain.

The simplest eye-care habit for people who stare at screens.

The American Academy of Ophthalmology's 20-20-20 rule is easy: every 20 minutes of screen time, look at something 20 feet away for 20 seconds. Look20 does one thing well — it reminds you at the right moment so you don't forget.
