Do Blue Light Blocking Glasses Actually Work?

There is a new trend taking social media by storm—computer glasses. As our lifestyles begin to rely more and more on screens, the effects of these screens on our eyes is becoming very apparent. You might suffer chronic headaches, blurred vision or experience general eye fatigue if you stare at a screen for too long.

That’s where computer glasses come in. These fancy tech glasses are designed to block the blue light waves your screens emit to reduce that eye strain and improve sleep quality. But do they actually work?

Yes and no.

Blue Light Glasses Can Improve Sleep Quality

If you’re on your computer anytime in the four hours preceding bedtime, computer glasses are a lifesaver. It is well-documented that blue light (which our brains associate with daytime) disrupts our circadian rhythms and can harm both sleep duration and quality.

By wearing lenses that block much of the blue light that our screens emit, you an mostly avoid those consequences. Your body creates sleep-inducing melatonin, and you fall swiftly away into dreamland when bedtime rolls around. Sheer bliss.

Blue Light Glasses and Eye Strain

But what about digital eye strain? Can these glasses really improve the headaches and the feelings of dryness, fatigue and blurred vision that come with hours of screen time? Many researchers say no.

According to Adam Gordon, a clinical associate professor at the University of Alabama at Birmingham School of Optometry, ”Eye strain is about the disparity between the things you want to look at and the natural focusing of your eyes, and how long you do it.”

Gordon explains that our screens aren’t necessarily the issue. You can experience eye strain from reading a book for eight hours straight just as easily as from staring at a screen for eight hours. The problem is, few of us stare at books for that long—but with our increasingly digital workplaces, social media and Netflix, many of us are looking at screens almost constantly.

Unfortunately, computer glasses may not be the fix. There is little evidence that digital eye strain is blue light-related, or that blocking blue light can reduce eye strain in any way.

So while the science is mixed, how do these glasses actually feel?

My Personal Experience with Blue Light Blocking Glasses

I’ve been wearing Felix Gray computer glasses for about nine months now, and I have to admit, they are a game-changer. I used to get headaches and intense eye fatigue when working on my computer for more than two hours. Intensive days of 6+ hours of screen work utterly wiped me out—I actually felt like my vision was starting to deteriorate because of it.

So, when I stumbled upon a nice looking pair of Felix Grays (which look like normal glasses but have an almost imperceptible blue light-blocking coating on the lenses), I figured I’d give it them try.

Placebo effect or not, almost immediately I noticed I was able to work for longer bouts of time without suffering from digital eye strain—which is crucial when I am working and feeling in the flow. And yes, it is reassuring to know that I am not utterly wrecking my sleep quality with blue light when I have to work on late-night projects.

So, should you invest in computer glasses? Maybe. If you work on your computer (or watch videos) in the evenings, they will likely help your sleep quality. If you’re trying to stave off eye strain from being on your computer too much, the jury is still out. If you’re really curious, I guess you’ll just have to try them out and see for yourself.
