How it works
The 20-20-20 rule is the standard fix for digital eye strain: every 20 minutes, look at something about 20 feet away for 20 seconds, so your eyes' focusing muscle gets a rest. This timer just keeps count for you. Press start, work as normal, and when the break screen appears, look out a window or across the room until it counts down.
Want it to happen without a browser tab?
A tab you have to remember to open is still a tab you'll forget. Eye Rest is a native Mac app that runs this in the background and, when it's time to rest, fades your whole screen into a hand-painted scene for the twenty seconds, with a gentle heads-up first and a free skip. The bet: a break you look forward to is one you actually keep. This browser timer is a free taste of the idea.
