F.lux, Free Software That Protects Your Eyes At Night

If you are like me, one who spends a lot of time looking at computer screens, tablets and phones even at night, you might want to consider checking out this nifty little tool called F.lux. What F.lux does is it changes your computer/laptop screen’s color balance, an important aspect to protect your eyes against the blinding glare especially at night.

I was quite skeptical at how well F.lux would work, but having used the computer for nearly 20 years my eyes has a tendency to get really tired at night. The first thing I noticed about the default settings of F.lux is that it makes your screen color really orange at night, don’t let that get to you because that setting is meant for halogen type of lightings. If you have very warm lightings at home, you might be alright with the default but I have cooler fluorescent lightings at home/office and I found 4700K setting to be the most comfortable for my eyes.

F.lux changes color temp, not brightness

I have used F.lux for just over a week and I’m already a fan. My computer screens looks better at night, my eyes are more comfortable and less tired than before. Note that I did find the colors a bit distracting first couple days but once I’m used to it, it doesn’t feel different anymore. I have installed F.lux windows and mac platforms and they all work very well, there’s even a reply on Quora that F.lux might find its way into Cydia soon and I’m really hoping to use it on my jailbroken iPad. I highly recommend this tool if you look at screens at night, also if you are a parent and your kids are already using computers for their school work this tool might just keep their eyesight perfect for a longer while.

F.lux settings, change it to your comfort level

Here’s something I didn’t know as well:

“We’ve spoken with a few clinicians and some researchers, and we’ve also spent a little time studying the literature regarding sleep.

The popular treatments for sleep disorders today focuses a lot on “blue light in the morning”, and the consensus view seems to include avoiding blue light within two hours of sleep. Practitioners we’ve spoken with agree that blue light can delay the onset of sleep, but the research seems mixed about whether or not blue light affects the quality of sleep.”Sleep Research by F.lux
