Many of us usually use the computers and laptops throughout the day including evenings and late nights, the darkness at nights cause computer screen to emit a glow that is not comfortable to look at.

However adjusting the contrast and color over and over again could be quite a hassle and we usually leave the settings the same throughout the day.

If you feel uncomfortable watching the computer screen at nights, a really useful and freeware ^[1] software called F.lux is what you should definitely be using.

F.lux makes the color of your computer’s display adapt to the time of day, warm at night and like sunlight during the day.

It’s even possible that you’re staying up too late because of your computer. You could use f.lux because it makes you sleep better, or you could just use it just because it makes your computer look better.

Flu.x will automatically detect your location and apply different color schemes based on the the time, however you can change the location and color settings to suit your own needs, by clicking on the Change settings button.

Flu.x will work on Windows XP, Windows Vista ^[2] and Mac, they also have a version that will work on Linux.
