What does f.lux exactly do?  

Depending on the time of day, f.lux changes the color temperature of your computer’s display (warms up the colors) and makes it easier for you to look at the screen. During the day, everything is okay and your screen looks good (except when it’s sunny). When at night, you’ll notice that it’s quite difficult for you to look at the screen for a long time. f.lux makes the color of your computer’s display adapt easily to each time of day, so when you look at the display, you will get the feeling that you are looking at the screen in the perfect conditions i.e. under the indoor light.

If you decide to use it, you’ll notice the changes in your sleep - you’ll sleep much better, because your eyes won’t be affected by glowing and strong light from the display.

How does it work?

During the day we’re exposed to daylight, and very often bright sunlight that has blue (cool) color temperature. In moments like these, you must admit that it’s difficult to work on laptop outside with all the light. On the other hand, at night there’s no sunlight and instead, we depend on the indoor lightning that our eyes can tolerate much easier because it’s sensed as warmer.

Can I just adjust screen brightness?

Sure you can, but it doesn’t affect the blue light on the screen. You can adjust the screen’s brightness depending how light/dark it is around you, but you can’t change the color temperature that way. In order to sleep better and not bother your eyes, you need warmer colors on your screen. f.lux uses warmer colors at night and makes white colors appear a bit darker. This should calm your eyes and give you a better experience working at night on your computer.
