Flux is a tool I come across while I was reading Shawn Stevenson’s book Sleep Smarter (Amazon affiliate link). Shawn mentions it among the tools he recommended to help people reduce the mental and physical strain induced by long exposure to digital devices. Flux helps alleviate from the eye strain caused by sustained exposure to the light coming out from our digital screens. What it actually does is that it regulates the colors of the display of your computer so that the display “adapts to the time of day, warm at night and like sunlight during the day.”
I have installed it on my Mac a couple of days ago, and since I am a night owl who spends most of his waking night time in front of the computer screen, I can certainly confirm that it does an amazing job. All you need to do is input your location and the kind of lighting you have and Flux does the rest. It “makes your computer screen look like the room you’re in, all the time. When the sun sets, it makes your computer look like your indoor lights. In the morning, it makes things look like sunlight again.”
Flux is free and is available for Mac, Windows and Linux.
