Science-Backed Blue Light Glasses Benefits for Sleep and Energy
March 10, 2023 • 7:08 AM
You know that feeling when you’re exhausted but just can’t seem to fall asleep? That might be your late afternoon coffee — or it might be something else entirely.
Nowadays we spend far more time on digital devices like laptops and smartphones than ever before. And all that screen time is bound to affect us.
Let’s look at what blue light is and whether or not it’s harmful. We’ll also explore some blue light glasses benefits, including what they can and can’t do for you. Then you can decide for yourself if you need blue-blocking glasses in your life.
What Is Blue Light?
Blue light is part of the visible light spectrum, with a short wavelength of 380-500 nanometers. We’re surrounded by sources of blue light every day — it comes from the sun, computer screens, televisions, tablets, and any fluorescent or LED lights.
In some ways, high-energy blue light can be good for you. It promotes alertness, boosts your memory and mood, and improves cognitive function. That’s all good stuff — during the day when you’re working and want to be on top of your game.
On the other side of the equation, there’s been a lot of talk about the harmful effects of blue light exposure on your eye health, including potentially damaging your retinas or causing eye diseases like cataracts or macular degeneration. The research into this is still ongoing.
What we know for sure though is that getting too much blue light at night isn’t good for us. Prolonged exposure to blue light suppresses melatonin production — and melatonin is the hormone that regulates your sleep cycle (also known as your circadian rhythm). That’s why if you work on your computer or watch TV late at night, your sleep quality suffers. You may struggle to fall asleep, or manage to get to sleep but then keep waking up.
The Benefits of Blue Light Glasses
You might think that not sleeping well isn’t such a big deal, but it has a chain reaction of effects.
For example, it impacts your ability to think straight, affects your memory, and shortens your attention span. On the emotional side, it can trigger anxiety and stress, potentially leading to depression or mental illness in the long term. And it reduces your energy levels and impairs your immune system, leaving you more susceptible to illness.
Beyond that, sleep deprivation has been linked to diabetes, cardiovascular disease, obesity, and many other chronic health problems.
Worried yet? It seems pretty overwhelming.
Luckily, a simple pair of blue light glasses benefits your sleep — and by extension, your health.
Blue light filtering glasses are designed to block some of the blue light coming your way, allowing melatonin to do what it’s supposed to and help you sleep.
Blue light lenses come with either clear or tinted lenses, depending on how they’re made, and they can be non-prescription, so you can wear them even if you don’t need regular eyeglasses. They can also be an add-on to prescription glasses.
Do Blue Light Glasses Work to Reduce Digital Eye Strain?
While blue light glasses benefits include improving your sleep and, as a result of that, your general health, the evidence suggests that what they don’t do is address digital eye strain.
Digital eye strain — or computer vision syndrome (CVS) — is the result of spending too much time focusing on an electronic device, while dealing with the glare from the screen — and not blinking enough.
Some symptoms include:
If you’re suffering from digital eye strain, blue-light-blocking glasses may reduce the glare slightly, but they’re not the solution. However, there are a few other simple things that can help:
Try to blink more often, and if need be, use eye drops to keep your eyes moist.
Apply the 20-20-20 rule: Take a break every 20 minutes or so to change your focus from your digital screen to something about 20 meters away for 20 seconds.
Get an anti-glare screen to ease the stress on your eyes.
It’s also worth visiting your optometrist to check if you need contact lenses or computer glasses. While reading glasses and distance glasses help you see close and far away, respectively, computer glasses help you see clearly in the middle distance — which is where your computer probably is.
If you’re suffering from age-related presbyopia too and struggle to read anything close to you, your eye doctor may recommend progressive lenses for your computer glasses. These updated bifocals have a bottom section that helps you see clearly when you read and a top section for focusing on your computer in the middle distance.
So Who Should Wear Blue Light Glasses?
You’ll benefit from blue light glasses most if you spend a lot of time in the evening on any of these activities:
Using your smartphone
Reading on your tablet
Working on your computer
Playing video games
In these cases, investing in some blue-blocking lenses could dramatically improve your sleep and your health.

Take Advantage of Blue Light Glasses Benefits
Blue light is a high-energy form of visible light that has positive effects on your brain and your mood during the day. However, too much exposure at night can interfere with your sleep cycle, leaving you feeling tired and groggy in the morning, and affecting your health in many other ways.
Blue light glasses benefits include blocking much of that blue light so melatonin production can happen normally. Get a pair of blue-light blockers from Pair Eyewear today — and protect your sleep, your health, and your quality of life.
