A simple tool for MacOS to combat eyestrain.
Eyesaver displays a system dialog every twenty minutes to remind you to look away from the screen for twenty seconds. The dialog will disappear automatically after twenty seconds.
While the name of this repository is eyesaver, the actual program is a bash script called eye for short.
Clone the repository and run
chmod +x eye && ./eye i
to initialize the script.
This will install the eye script in $HOME/bin, so make sure $HOME/bin is in your $PATH.
Simply run eye to see more options.
This link was really helpful for figuring out how to use the launchd utility.
