f.lux 4.112 Beta


Ever notice how people texting at night have that eerie blue glow? Or wake up ready to write down the Next Great Idea, and get blinded by your computer screen? During the day, computer screens look good—they're designed to look like the sun. But, at 9PM, 10PM, or 3AM, you probably shouldn't be looking at the sun.

f.lux fixes this: it makes the color of your computer's display adapt to the time of day, warm at night and like sunlight during the day. It's even possible that you're staying up too late because of your computer. You could use f.lux because it makes you sleep better, or you could just use it just because it makes your computer look better.

Changes in f.lux 4.112 Beta:

  • Option to turn on Windows Dark mode only at night (See “Effects…” > “Use Dark mode at sunset”)

  • Solar time!

Solar Time?

We added “Solar time” to the preferences, because we’re think it’s important. It’s not done because it’s going to have a more prominent role in the future, but for now, it’s here just to spark some discussion.

If your solar time is after the current clock time, it’s likely that you live in a place that’s easy for night owls to be (because they can wake up late). And if you’re in a place where the solar time is much earlier than what your clock says, it’s easier for early birds, because they can go to bed early.

Most of us wake up with our clocks (about 80% of people wake with an alarm clock), but our bodies tend to synchronize to the light we see. So when these two signals get far out of alignment, we sleep worse and have more health problems.
