It is very small python program that sends a desktop notification that reminds you to give rest to your eyes since screening for a long time can damage your eyes. Its based on the 20-20-20 rule i.e after 20 minutes of screen time you need to look at object at 20 yards for 20 secs.
One can run it by typing:
$ pythonw main.py
in the terminal from the Eye_Protector folder. You need to use pythonw to run it in the background. One can also use the windows task scheduler to start the program when the computer starts up.
