Show HN: Tool to combat eye fatigue

I am not sure if there are any scientific material concerning the 20-20-20 thing, just some blog posts and a webMD page: http://www.webmd.com/eye-health/computer-vision-syndrome?pag... . Its just something to try, as taking eye breaks every now and then is probably good. But, thanks for the feedback!

For more general purpose break management tools, theres some pomodoro (not sure how scientific that is either) time/break managing tools online, but I might add some bars or user customizable bars if I get around to it. I usually try to stretch or take some deep breaths whenever my 20 minutes are up. For something like going outside, you could just add a weekday timer/reminder on your phone/watch at foo and bar times of day.

I've used a similar app that made a beep after a certain number of minutes, but I made a habit of ignoring it after a week.

Now I use Breaktime (only for OSX), which inserts itself in the system tray part of the screen and displays a big overlay when "time's up". It is more effective because it forces me to get up.

You could build a browser notification that gets the focus of the user.
