f.lux Reviews

by grex about f.lux on April 6, 2018:
f.lux is a completely free piece of software that makes it easier for you to get a good night's rest even if you use your computer after the sun sets. Our digital screens produce a form of blue light that our body interprets as sunlight. This blue light can inhibit the production of melatonin, which is a chemical our body releases to regulate sleep.

By staying up late at night on a computer that doesn't use a blue light filter, you can be making your sleeping worse. f.lux fixes this by syncing to your geographical location to enable its blue light filter around sunrise and sunset each day. If you have Philips Hue smart bulbs, you can even link them to f.lux to make your whole house have a blue light filter.

The service is available across a wide variety of platforms and works very well for removing the blue light that inhibits restful sleep. However, it should be noted that the filter does change the appearance of the content on the screen, so color sensitive work like Photoshop shouldn't be done while you're using this software. Movies and games are also affected, so you'll want to remember to turn off the filter if you want accurate color reproduction.

The research behind f.lux is ongoing and available on their blog if you're curious why removing the blue light from our screens can improve sleep quality. It's a fascinating look at how our bodies have adapted to use light in ways we may not even consider.
