Take care of your eyes!
This extension sends you notification in every 30 or 60 minutes to remind you to rest your eyes.
By clicking on the notification you can stop the reminding process witch continues for 1 min.
You get to choose the starting and end time when you would like to start the reminding process and also disable them in days like weekends or always.
Set custom messages.
Disable audio if it bothers you.
More updates are coming soon... :)
