Blue Light Filter App vs Blue Light Blocking Glasses

January 30, 2017

If you’ve ever used Apple NightShift or have downloaded f.lux, you’re probably familiar with the effects of Blue light on your eyes and your sleep. You may have even experienced some alleviation of Digital Eye Strain (also known as Computer Vision Syndrome) symptoms. If you’re really lucky, you might even be getting a better night’s sleep because you’re using NightShift for that last peek at Facebook before nodding off to sleep.

I use these apps, why do I need Blue Light filtering glasses? The truth is, these apps are both great tools for your visual lifestyle. Unfortunately, they are only part of the solution.

Better Productivity. Better Sleep. Guaranteed.

F.lux is certainly a valuable tool, and our spectrometer has shown that in a darkroom, f.lux can filter as much blue light as our glasses do. But we are guessing you don’t work in a darkroom. Chances are that you are working in a corporate office or a home office. While it is easy to point fingers at the computer screen as the culprit for your burning eyes, the fluorescent lights overhead may be just as much to blame. By taking your protection off of the screen and into glasses perched on your face, you are blocking not only the light from the computer screen but also from the environment around you.

But PupilBox, when I am staring at my phone at night, I AM in a dark room! I even have blackout curtains in my bedroom!

In order for your circadian rhythm to be in sync as it should, it really needs to mimic the natural sun cycle. This means that unless you retreat to your black-out-curtained fortress at sunset and only interact with the world through your NightShift filtered screen, chances are that you are being exposed to artificial blue light later in the evening than you should be. By wearing PupilBox blue filtering glasses once the sun sets, you can stimulate melatonin production in a natural cycle and enhance your sleep.

Digital Eye Strain (DES)  isn’t just caused by Blue Light. We wish it was, because then our glasses could totally solve the problem! Unfortunately, there are numerous factors that make your eyes tired and your productivity plummet by causing DES. One of the contributors can be the reduced blink rate which occurs during screen use. We know that blink rate can decrease by as much as a factor of 5 during screen use, but why?
