20-20-20 Rule (for eyes)

The “20-20-20 rule” for relieving eye strain (often caused by extended computer use) is that after 20 minutes, take a 20-second break and look at objects at least 20 feet away.
 
The 20-20-20 rule might have been created by Dean Evan Hart, who was a research scientist at Columbia University and director of the low-vision clinic at Harlem Hospital. In Newsday (Hempstead, NY) on March 22, 1998, Hart said, “When working with a computer, take a vision break every 20 minutes. (...) Look 20 feet or more away for 20 seconds to relax eye focusing and don’t stare. I call it my ‘20-20-20 rule.’”
 
“To avoid straining your eyes at work, use the 30-30 rule. After 30 minutes of work, quit your job and buy a 30 acre farm in the middle of nowhere” is a related joke.

If you’re working all day on the computer, you can fend off eye strain by following the 20-20-20 rule. Every 20 minutes take a 20 second break to look away at objects at least 20 feet away…and you’ll reduce your chances of computer related vision problems.

According to the Saskatchewan Association of Optometrists, a good rule of thumb for a visual break from the computer is the “20-20-20” rule: for every 20 minutes of computer work, take a 20-second visual break by focusing on a distance of at least 20 feet.

Deconstructing the 20-20-20 Rule for digital eye strain
February 22, 2018
Brian Chou, OD, FAAO, FSLS
Most optometrists have heard of the 20-20-20 Rule for preventing and relieving digital eye strain. The catchphrase suggests taking a 20 second break every 20 minutes by looking 20 feet away.
 
Numerous sources now refer to it, including the American Optometric Association (Figure 1) and the American Academy of Ophthalmology. Maybe you, like many other eyecare professionals, offer this guidance to your patients. But have you ever wondered where this came from?
