Staring at a monitor all day can wreak havoc on your peepers. F.lux dynamically adjusts the color tones of your PC monitor based on your physical location.
During the day, F.lux keeps your display nice and bright. As the sun sets, the program gradually shifts your monitor over to warmer, cozier hues.
F.lux sounds simple—and it is—but the program truly helps reduce eyestrain and makes it easier to stay relaxed working long into the night. It takes some getting used to, but it's worth it.
