AOA-Twenty-Twenty-Twenty 👀

This is a small MacOS utility that will display a notification every twenty minutes to remind users to look for 20 seconds at an object at least 20 feet away. It is based on a recommendation by the American Optometric Association.

Your eyes are important, take good care!

Requirements

This utility can only run on MacOS. It was tested on MacOS Monterey and later.

Installation

git clone https://github.com/StefPac/aoa-ttt.git
cd aoa-ttt
./aoa-ttt-install

To uninstall:

./aoa-ttt-uninstall

The installer registers a launchd agent at ~/Library/LaunchAgents/com.aoa-ttt.plist that fires every 20 minutes. To remove it manually, run launchctl unload ~/Library/LaunchAgents/com.aoa-ttt.plist and delete the file.
