f.lux

f.lux is a display management tool designed to align your screen's brightness and color with your internal biological clock. During the day, your screens look like sunlight, but as the sun sets, the software automatically transitions your display to a warmer, amber hue. This shift mimics indoor lighting and reduces the blue light exposure that often interferes with your sleep patterns and causes digital eye strain.

You can customize the experience by telling the software exactly what kind of lighting you have and where you live. It then handles the transitions automatically, so you never have to manually adjust your monitor settings as evening approaches. It is a set-it-and-forget-it solution for anyone who spends long hours in front of a computer, especially during late-night sessions.
