- epmaybe 6y agoThe story behind 20-20-20 is actually pretty interesting, take a look! TL;DR: an optometrist came up with it in 1991, to help corporate workers come up with a quick and dirty rule to reduce eye strain. There's no scientific basis behind it (doesn't prevent worsening vision, etc etc) https://www.optometrytimes.com/view/deconstructing-20-20-20-rule-digital-eye-strain https://www.optometrytimes.com/view/deconstructing-20-20-20-...
