Ever notice how at night when you use your computer your face has a blue glow? That is because our monitors are designed for use in the day, so the light coming from them is supposed to be like the sun. But it can't be good for your eyes to look at the sun at say, 9 PM or 2 AM. I know a lot of people use the computer after dark so this is a very useful application.
Its called F.lux. You can get it
here. It is available for Windows, Mac, Linux, Iphone, and Ipad.
"So what exactly does F.lux do to save my eyes from a lot of strain?" you may ask.
It changes the warmth of the colors on the screen to suit the time of day.
