f.lux is a really handy tool that allows you to adjust the colour temperature on your display. If you stare at a screen for too long, then the glare from the display begins to hurt your eyes. To start with, turning down your monitor's brightness may help you, but brightness is not the really issue. The colour temperature is what causes the problems.
Most computer screens emit a bluish light, which looks great in daytime, but it becomes uncomfortable to look at when the sun dips below the horizon. Not only can your screen become uncomfortable to look at, it can also affect your sleep patterns*.
F.lux works by calculating the approximate sunset time for your location. At sunset, your computer screen will mimic nature, gradually warming up the colours. This, in turn, blends in better with the surrounding light.The app is very easy to navigate and configure in a few clicks. the adjustments can be made with sliders across the main window, which alter the daytime and night time calibrations.
If you spend a large amount of time looking at your computer screen, then f.lux is definitely something that you should check out.
*There has been research which suggests reading on a tablet for a couple of hours before you go to sleep can delay your sleep pattern by approximately an hour.
This new version of f.lux has a grayscale mode and new key to turn it on: Windows + End.
You may already know about Tristan Harris and the Center for Humane Technology. They’ve explained how apps mess with our attention, so even the colours used on our screens are chosen to distract you. At first, we didn’t think this problem would be as bad on the desktop as it is on your phone.
The big surprise is how distracting the icons on the top and bottom of your screen are. These icon colours are the kind of thing you see in candy stores and on fire alarms, but we have to ignore them just to get work done. Without those colours, your computer looks more like a magazine that can help you focus on reading or thinking—it feels different, like a sheet of paper.
Also, turning your devices to grayscale does not remove blue light, so f.lux will continue to do what it does.
In this version, there’s also dusk-to-dawn support for people with Hue lights, so you can put Hue lights outside and use f.lux to turn them off during the day.
There are some bugfixes too.
