Hey ubuuchons look what I found.http://stereopsis.com/flux/
Apparently it's a software that adjusts the brightness/color of your screen depending on the time of day. This way when it's late your computer screen won't completely kill your eyes, as well as fool you into thinking you're not tired because of the brightness of your screen. Just plug in your coordinates and go. You even have the option for a slow transition so it's not so sudden.
The orange color was a little annoying at first, but it really does seem to help my eyes. The only problem with it is that if you want to uninstall it you have to manually get rid of all the registry keys and program files since the uninstall doesn't do jack shit. That and there can be some issues with fullscreen programs like Yume Nikki/fangames, though there's an option to disable it for an hour.
It's definitely a good idea though.
