Gives timely reminders to take breaks for the safety of your eyes.
20-20-20 EyeCare is designed to improve eye health and reduce eye stress. It does so by implementing the 20-20-20 vision rule. The extension reminds the user to look away from their screen every 20 minutes by having a new page popup after the 20 minutes for 20 seconds and then automatically closing. 
How to use:
1) Install the chrome extension from the chrome web store.
2) Click on the popup icon to access the controls.
3) Press start when ready to begin the session. Press clear when done or taking a break from screen usage.

Note: If any issues with the diplayed time arise, please just click the clear button and start the session again to troubleshoot the issue.
