OptiSit

OptiSit™ is a lightweight, multiplatform calculator of the optimal distance between your eyes and your screen.

View distance is very important when you watch a screen for a long period of time. If you are too close, you will be too exposed to the screen's backlight. If you are too far, you will inevitably lean forward and squint to see better, but your eyes will tire and your back will start to hurt. OptiSit™ helps you find the most comfortable distance for your eyes and thus reduces fatigue.
