F.lux App

Save Your Eyeballs with F.lux 

At 6 p.m. on any given work day, there’s a good chance that at least half of the Block Club team is still at the office. And there’s an equally good chance that, upon rising from our computers, one or two of us will startle our co-workers with an unintentional re-enactment of 28 Days Later, staggering around, red-eyed and dumbfounded by the world beyond our glowing computer screen.

A few weeks ago, a friend introduced me to an app called f.lux, and the difference for my eyes at the end of the day has been incredible—it makes a huge difference in productivity and overall eyeball / life experience. F.lux removes the harsh glow of blue light from your computer screen once the sun has set, so your brain can stop thinking it’s still 2 p.m. when you’ve only got two hours to go until bedtime.

It’s incredibly easy to use—you just enter your location, and f.lux automatically adjusts your computer’s colors and brightness based on the sunrise and sunset times in your city. It turns your screen an odd shade of orange, but it happens so gradually that I have a hard time even noticing it now. If needed, you can toggle back to full screen brightness and color—it’s actually a pretty harsh shock to jump back to what I would have been seeing before.

If I had to describe my f.lux experience in a few words, it would be this: over my dark, bleary-eyed computer experience, the clouds parted, and through them, finally, shone the sun. Except the sun was actually my computer screen, and it was a strange, gentle shade of orange, and… I gently stared at it for several more hours of work. The end.
