The 20-20-20 rule, explained
A simple habit: every 20 minutes, look about 20 feet away for around 20 seconds.
The idea
Every 20 minutes, shift your gaze to something roughly 20 feet away for about 20 seconds. It's an easy way to give your eyes a regular moment to relax during screen work.
Making it automatic
The hardest part is remembering. Gentle, well-timed reminders turn the 20-20-20 rule into an automatic habit so you don't have to keep track yourself.
