f.lux allows you to adjust your display's colour temperature. The glare from a display can cause eye irritation if you stare at it for too long. You can reduce the brightness of your monitor to help, but that is not the problem. Problems are caused by the colour temperature.
The majority of computer screens emit a blueish light that is beautiful in the daytime but becomes uncomfortably distracting when the sun sets below the horizon. Your sleep patterns can be affected by your screen.
F.lux calculates the sunset time for your area. Your computer screen will gradually warm up the colours as it mimics nature at sunset. This makes the computer screen blend in with the surrounding light better.
If you spend a lot of time looking at your computer screen then f.lux is something you should definitely check out.
*Research suggests that reading on a tablet for at least an hour before going to bed can disrupt your sleep patterns by about an hour.
