F.lux Exposed: The Truth About Blue Light Filter Apps and Blue Light Exposure



Do you have f.lux installed on your computer?


F.lux is a free blue light exposure protection app you can install on your desktop to filter out the blue light from your monitor. The app automatically shifts the color to a reddish amber as soon as the sun goes down.


Night Shift is another great blue light filter app option you can try out on your smartphone or tablet.


Blue light exposure problem solved! Right?


Not really…


Let’s find out the truth about the effectiveness of these blue light filter apps.


The problem with blue light filter apps

We all know the problem with blue light exposure is real. All the blue light from your devices is throwing off your circadian sleep rhythms. Lack of sleep can have very serious health consequences. You’ve probably felt it already in the quality of your sleep.

The good news is, with every problem comes a solution, and one of the solutions to the blue light exposure is f.lux (and other similar blue light filter apps out there).


That’s right BUT this solution comes attached to another problem.


The problem? The word “filter”.


A filter works like a strainer. It keeps out some particles, but allows others to pass through.


Therefore, the blue light filter apps allow the blue light to come through, it doesn't stop blue light from completely getting through.


Unfortunately, that’s not the only problem we’ve identified with blue light filter apps. Blue light is not only released by our electronic devices, but also by our TVs and all sources of artificial light.


We needed a better blue light exposure solution, and thanks to Swanwick Sleep we have one.






Blue Light Exposure Eliminated!

At Swanwick Sleep, we believe sleep is a must! Our mission is to help you achieve it.


We don’t do things by halves. To prove it, we created our Swannies Blue Light Blocking Glasses to not only filter but block all the blue light in your space.




You can wear your Swannies at night (at least one hour before going to sleep) to protect your eyes from all the blue light in LED emitting street lamps, while watching LED electronic screens, at baseball games, or anywhere blue light exposure can be an issue.


There’s increasing scientific evidence that blue light may not just damage your sleep, but your eyes as well. The simple color shift provided by blue light filter apps is not enough to prevent such damage.


If you’re already wearing glasses, it might as well be Swannies. That way you’re guaranteed healthy eyes and a good night’s sleep! Win-win!

That’s not to say your f.lux doesn't offer any protection from blue light exposure. But if you’re wondering why you still haven’t achieved the peaceful sleep you’re dreaming about, Swannies just may be the answer for you.


Swannies for the win!
