f.lux screenshotDid you ever wake up ready to write something important, and get blinded by your PC display?

During the day, PC displays are looking good - they are created to look like the sun. But, at 10PM, 9PM, and 3AM, you perhaps shouldn't be stare at the sun.

f.lux resolves this issue: it makes the color of your PC's display adjust its brightness to the time of day: warm at night and bright during the day.

f.lux makes your PC display look like the room you are in, all the time. When the sun sets, it makes your PC look like your indoor lights.
