My journey began a few years ago when I saw an ad for Felix Gray, a startup founded by David Roger and Chris Benedict that sold (prescription) glasses designed to reduce glare and filter out blue light rays.
This ad was my first introduction to the idea of wearing glasses to block blue light, and I had a lot of questions.
Here’s what I found after digging deep into the literature on whether blue light blocking glasses really work (short answer: maybe), and after finally trying on a pair of prescription blue light blocking glasses from Liingo Eyewear and Zenni Optical. (Update: I now religiously wear Liingo and Zenni’s blue light-blocking glasses when working from home amid the COVID19 crisis.)

Let’s dig into the weeds to see why the focus on the “harmful effect” of “blue light” is somewhat misplaced:
Companies like Zenni and EyeBuyDirect claim their blue-light-blocking glasses block “harmful” blue light rays. But is blue light really harmful?
Blue light is simply part of the spectrum of visible light. Blue light is part of the sun’s rays and is also emitted by some LEDs and other artificial lights.

During the day, wavelengths of blue light are “beneficial … because they increase attention, reaction times, and mood,” according to Harvard University’s Health Letter.
Blue light is why people tell you to go out in the sun after they get rid of a red eye.
It helps regulate the body’s natural circadian rhythm and blocks the natural production of the hormone melatonin. (Naturally occurring melatonin “plays a role in sleep”).
Blue light is also believed to be beneficial in the treatment of Seasonal Affective Disorder, a temporary depression that corresponds to a lack of daylight in the late fall, winter, and early spring.

However, by blocking melatonin at night, exposure to blue light can inhibit your ability to become drowsy and fall asleep.
As the Harvard Health Letter also points out, some studies have gone so far as to link nighttime light exposure to heart disease, certain cancers and more.
We are increasingly exposed to blue light at all hours of the day thanks to our computers, televisions, tablets and mobile phones, not to mention indoor lighting.
Televisions, computer monitors and telephones are primarily illuminated by LEDs, which emit light wavelengths between 400-490 nm, which overlap with the range of “high-energy visible light” in the blue and violet range.

So if you look at a computer, TV, tablet or smartphone at night while the light appears white, your eyes are exposed to high-energy visible light.
That’s not necessarily a bad thing during the day. And by the way, we are probably exposed to more blue light by going outside in the sun than by looking at our digital devices.
But by emitting blue light waves that block the production of melatonin at night, your phone, tablet, computer, TV, and light bulbs can impair your ability to relax, become drowsy, and fall asleep.
As I work from home and find myself in front of my screen more at night, I know I expose myself to more of the blue light waves closer to bedtime than I would otherwise.

One study concluded that blue light from digital devices may contribute to symptoms of visual fatigue “as blue light spreads throughout the eye, increasing the effort required to maintain visual focus.”
At the same time, the study notes that “there is currently no evidence to suggest that the visible blue light emitted from digital devices can damage the eye.”
That said, given the amount of time I’m on the computer these days, I’ll take advantage of any benefits I can for eyestrain.
Blue light blocking glasses are meant to filter the blue light wavelength before it reaches your eyes. In addition to a blue light filter, some companies’ lenses also contain an anti-reflective coating and/or UV protection to filter out glare and ultraviolet rays.

It’s impossible to say whether blue light blocking glasses “work” without defying the claims of the retailers trying to convince us to buy them.
The reality is that the answer depends on the claim and the quality and features of the product. Here are three claims I’ve seen from retailers that block blue light:
A common claim made by online retailers is that blue eye blocking glasses can reduce irritation, dry eyes and/or eye strain associated with the use of computers, tablets and phones.
Zenni Optical, one of my favorite places to buy super cheap glasses, cutely calls this phenomenon FryEye, although it’s more commonly referred to as digital eye strain or computer vision syndrome.

Studies suggest that blue-light-blocking glasses “may reduce eye strain associated with computer use based on a physiological correlation between eye fatigue and on subjects’ reporting of symptoms typically associated with eye strain,” and could be used as an additional tool to reduce eye strain to prevent to the retina of blue light.
Glare is one of the contributing factors to digital eye strain and computer vision syndrome,
