A very simple program that reminds you each 20 minutes to look at something 20 feet away for 20 seconds (The 20-20-20 rule, saves you from eye strain).
Features:
- The number of minutes, feet away, and seconds are adjustable, it could be 30-30-30, 40-40-40, anything you want.
- It gives you a notification when the timer ends each time.
that's it.
