Thanks to mouser I found this:
So all we need is a bit of code what would let the user set the interval and a way it will alert the user to do exactly what's necessary!
This seems not only to be healthy but would also be a cool program to mention on lots of different sites, including lifehacker and stuff.

14. Prevent near-sightedness!
Poor distance vision is rarely caused by genetics, says Anne Barber, O.D., an optometrist in Tacoma, Washington. "It's usually caused by near-point stress." In other words, staring at your computer screen for too long. So flex your way to 20/20 vision. Every few hours during the day, close your eyes, tense your body, take a deep breath, and, after a few seconds, release your breath and muscles at the same time. Tightening and releasing muscles such as the biceps and glutes can trick involuntary muscles -- like the eyes -- into relaxing as well.
