Ultimate Blue Light Blocking Glasses Guide of 2023
Blue light blockers have surged in popularity in recent years. As scientists continue to explain the harms that harsh light can have on the strength and health of the eyes, more and more users are turning toward blue light blockers to improve their eye health while still continuing to do the things they love to do.
Today, many people use glasses, filters, software, and other tools to block blue light. Blue light keeps you awake at night. Some believe blue light also causes vision problems, headaches, anxiety, and restlessness. In the long-term, overexposure to blue light can harm the health of our eyes and cause unnecessary strain.
That’s a problem because blue light is all around us. It’s in our digital displays, including laptops and smartphones. It’s also in fluorescent lights, sunlight, and most other visible forms of light. Clearly, blue light cannot be avoided by most users. Even since the advent of the coronavirus pandemic, ultraviolet lights have soared in demand and emit blue light when being used. Add to the mix of EMF protection from possible 5G radiation, and adding some blue light blocking glasses right into your everyday usables seems to be rather modest yet modern in an age of super WiFi, computer screens and digital devices surround us all day long.
This makes efforts to block the eyes from the blue light that we're forced to view on a daily basis even more necessary. Experts expect the blue light eyewear market to grow from $20 million in 2023 to $27 million in 2024. Blue light blocking glasses can be used for reading, gaming, TV, phones, and more.
With so many blue light blockers available today, it’s hard to know which blue light blocker is best for you. Today, we’re highlighting the best blue light blocking glasses.

How We Ranked the Best Blue Light Filtering Glasses
All blue light blockers make similar promises: they claim to block blue light, reduce eyestrain, help you fall asleep, and prevent headaches. We used the following criteria to rank blue light blockers:
Blue Light Blocking Effectiveness: You’re buying blue light blocking to block blue light, so this was the most important thing we considered.
Lens Clarity: The best blue light blockers block light without creating a noticeable yellow tint. Some cheaper glasses just use a yellowish lens to block blue light. Some even use an orange or red tint to block blue light.
Proven Testing: The best blue light blockers companies have put their glasses through strict testing, including the UV400 protection test (proving the lens blocks or reflects all UV rays) and the blue light blocking capacity test (proving the glasses block blue light without reducing vision).
UV Protection: The best blue light blockers use substrate processing technology to protect eyes from ultraviolet radiation and block UV400. Cheaper glasses do not.
Durability: Some eyeglasses are made from cheap plastic. Others are made from lightweight, durable materials like resin.
Style & Aesthetic Appeal: Some people wear blue light blockers at the office or in public. You want the glasses to look good.
Advertised Health Benefits: Some blue light eyeglass manufacturers exaggerate the benefits of their product, claiming you’ll reduce disease and illness by wearing the glasses regularly. Reputable blue light blocker companies make basic benefit claims – like better sleep, improved vision, and reduced headaches.
Price & Value: Some people want to spend $7 on a cheap pair of blue light blocking glasses. Others want to spend $30. The blue light blockers above ranged in price from $7 to $30, although we emphasized fair value at every price range.
Manufacturer Reputation: Some blue light glasses are cheap pieces from China. Others, like Livho, are made by designers in Italy with 20+ years of fashion experience.
Who Should Use Blue Light Blockers?
Anyone who wants to improve sleep, reduce headaches, and reduce blurred vision may want to use blue light blockers. Blue light blocking glasses are proven to block blue light, which can lead to powerful health benefits.
Anyone who spends long hours watching TV or using a computer at night, for example, may benefit from blue light blocking eyeglasses.
If you’re the type of person who sits in bed using a phone or tablet for an hour before going to sleep, then you may also benefit from blue light blocking eyeglasses. All of that late night blue light can be bad for your sleep, and glasses may be able to help.
People who work night shifts may also benefit from blue light glasses. Blue light glasses help your body maintain a circadian rhythm even when your rhythm doesn’t match the rest of the world.
Many people are surprised to learn that everything gives off blue light. Yes, any source of visible light – including the sun, a lightbulb, or a touchscreen – gives off blue light. This blue light can impact your sleep and cause other issues.
If you have experienced sleep issues, then you may benefit from blue light. Some people have trouble falling asleep, for example. Others have trouble staying asleep.
Our bodies are built to stay awake during the day and sleep at night. When your body stops noticing blue light – like at night – you produce melatonin, which may help you fall asleep.
Benefits of Blue Light Blockers
Blue light blocking glasses are trendy – but are they actually backed by science? Let’s take a closer look at some of the science behind blue light blockers and how the work.
First, it helps to understand what blue light is.
All visible light that humans wee contains the entire spectrum of the rainbow – from red to violet. Within that spectrum are blue light waves. Blue light waves help us stay alert and upbeat.
All visible light gives off blue light waves, including the sun, a laptop, and a lightbulb. Your body is exposed to blue light waves all day from the sun. When the sun sets, however, many of us are still exposed to blue light from artificial sources.
Blue light affects sleep. When the sun goes down, our bodies stop being affected by blue light. This sends a signal to your body to start producing melatonin, the hormone responsible for making us fall asleep. In caveman times, this bodily system fueled our natural sleep-wake cycle or circadian rhythm.
Sleep-wake cycles and circadian rhythm worked well in ancient times – before electricity and computer displays. Today, however, we’re exposed to light all day and into the night. For many of us, a smartphone screen is the last thing we see before closing our eyes at night.
Studies suggest staring at a screen for long hours is a problem. It leads to digital eye strain, which can cause health issues.
The American Optometric Association defines digital eye strain as “a group of eye- and vision-related problems that result from prolonged computer, tablet, e-reader and cell phone use.” As explained by Cleveland Clinic, digital eye strain is also called computer vision syndrome (CVS).
Symptoms of digital eye strain include blurry vision, dry eyes, headaches, and neck pain.
One 2011 study found that up to 90% of people experience some type of digital eye strain when using a computer. Common symptoms include eyestrain, headaches, ocular discomfort, dry eye, diplopia and blurred vision.
When we stare at digital screens all day and evening, we’re constantly exposed to blue light waves. These blue light waves are linked to health issues. There’s conflicting evidence of just how much blue light waves affect your health, but doctors agree that blue light certainly affects your circadian rhythm.
Digital screens are a particularly strong source of blue light. Fluorescent and incandescent bulbs give off some blue light, but LEDs give off much more blue light. That means when you’re using an LED smartphone, tablet, or TV screen after sunset, you’re exposed to a lot of blue light.
Because blue light affects your circadian rhythm, it can reduce the quality of your sleep. Poor sleep is linked with all sorts of health issues – from cardiovascular problems to obesity.
There’s conflicting evidence over just how bad blue light is for our bodies. Depending on who you ask, blue light causes no vision problems – or it leads to full-fledged blindness.
Some optometrists believe that blue light leads to eyestrain and focusing problems, for example, but does not lead to long-term eye disease or retina damage.
One study published in Scientific Reports in 2018, however, found that blue light could accelerate macular degeneration and increase the risk of other eye diseases. Researchers analyzed how eye cells responded to blue light in tablets, phones, and computers. They found that blue light can damage vision and generate poisonous molecules in the eye’s light-sensitive cells.
The American Academy of Ophthalmology, meanwhile, says there’s no evidence that blue light given off by screens causes eye damage. They argue that we’re exposed to blue light from the sun all day – and normal sunlight doesn’t damage our eyes.
“During the day, you get 10 times as much blue light from the sun as you do from your computer screen. Our bodies have evolved to deal with this light,” explains Dr. Raj Maturi, a clinical spokesperson for the American Academy of Ophthalmology, in a statement to CNET.
However, research from the American Optometric Association indicates otherwise. In a recent report, the AOA found that prolonged exposure to blue light (such as when sitting in front of a computer all day) can cause damage to your retina, the innermost layer of your eye that allows your brain to process visual information.
A non-profit organization called Prevent Blindness has released similar research. Their early research suggests that blue light contributes to eye strain.
It’s no secret that late night light exposure can disrupt melatonin. This study published in The Journal of Clinical Endocrinology in 2011, for example, found that exposure to room light in the late evening suppressed the onset of melatonin synthesis and shortened the duration of melatonin production.
Given all of this information, do blue light blocking glasses actually work? Can you really prevent blue light eyestrain simply by wearing glasses?
Blue light blocking glasses have filters in their lenses that block or absorb blue light. Some of the higher-quality glasses also block or absorb UV light.
When you wear blue light blocking glasses while working at a screen, it reduces exposure to blue light waves that would otherwise keep you awake. The glasses are especially beneficial when worn after dark, as artificial light is the only source of blue light at night.
There’s scientific evidence that blue light blocking glasses work as advertised.
A 2017 study by the University of Houston College of Optometry found that blue light emitted from digital devices could be contributing to the high prevalence of reported sleep dysfunction. Researchers found that wearing short wavelength-blocking glasses three hours before bedtime for two weeks led to a 58% increase in evening melatonin levels. Participants also reported sleeping better, falling asleep more easily, and staying asleep for longer.
A study in the Journal of Adolescent Health found similar results. Researchers told a group of young boys to wear orange glasses while looking at their phones for a few hours before bed. The boys felt “significantly more sleepy” than when they wore clear glasses. A 2009 study found similar sleep improvement results in a group of adults, with participants also reporting significantly better mood compared to a control group.
There’s also anecdotal evidence that blue light glasses prevent eyestrain. The blue light glasses above are backed by thousands of positive reviews on Amazon. Multiple influential media outlets have written glowing reviews for blue light blocking glasses.
Gina Tomaine of Good Housekeeping wore blue light blocking glasses every day for a week and was impressed with the results:
“Glasses like these are small miracles. My eyes felt more rested at the end of the day (probably from the reduced screen time and glare) and looked visibly less red and tired. Plus I got tons of compliments on my new glasses. I would recommend these to anyone concerned about their digital eye strain — though I would also recommend trying to cut down on LED lighting and screen time at night as much as possible.”
You can find similarly positive reviews from Forbes, BuzzFeed, Gizmodo, and other major outlets.
Before you rush to buy blue light blocking eyeglasses, however, it’s important to note that there’s still limited evidence they prevent digital eyestrain.
This 2017 study, for example, reviewed all available evidence on blue blocking (“BB”) glasses and found unimpressive results:
“We find a lack of high quality evidence to support using BB spectacle lenses for the general population to improve visual performance or sleep quality, alleviate eye fatigue or conserve macular health.”
In fact, no scientific study has verified the benefits of blue light blocking eyeglasses with regards to eye health. Yes, blue light blocking eyeglasses may help you fall asleep – but they have not been proven to improve eye health or reduce your risk of eye disease.
There is one proven way to reduce eye strain while using a screen for long periods: follow the 20-20-20 system. Every 20 minutes, look at something at least 20 feet away for 20 seconds. According to the American Academy of Ophthalmology, it’s a proven way to relieve your eyes during long screen sessions.
Other eye relief tips from the AAO include blinking more frequently, using artificial tears, adjusting brightness and contrast, reducing glare, and adjusting your computer position.
Frequently Asked Questions About Blue Light Blocking Glasses
The market is still new for blue light blocking glasses. This can make it difficult for consumers to obtain accurate and reputable information on the growing sector. This section will answer some of the most commonly asked questions about blue light blocking glasses.
Q: What is blue light?
A: Blue light is visible light in the spectral range from 400 to 500 nanometers (nm). Blue light comes from almost all forms of visible light, but it is particularly common in electronic devices, such as computers or phones. The light is known to cause a number of potential harms, as it can cause strain on the eyes.
Q: What do blue light glasses do?
A: Blue light glasses filter blue light, preventing fewer blue wavelength rays from reaching your eyes. Blue light disrupts melatonin levels, which could make it more difficult to fall asleep. It could also cause a number of other potential harms.
Q: How much blue light do blocking glasses filter?
A: Most glasses filter 80% of blue light, allowing you to see most blue color while still enjoying the benefits of blue light blockers. Blocking amounts depend on the brand, so be sure to consult your product's information for a complete answer.
Q: Why are some blue light blocking glasses tinted orange or yellow?
A: Some cheap blue light blocking glasses are tinted orange or yellow to block out blue light. This is the cheapest and most basic way to block blue light, and it causes everything to look orange or yellow.
Q: Can you wear prescription glasses underneath blue light blocking glasses?
A: Some glasses are fitovers, designed to fit over existing glasses. Most glasses above, however, are not designed to be worn with an existing pair. Consult the manufacturer instructions provided with your blue light blocking glasses before using.
Q: Will blue light blocking glasses improve sleep?
A: Multiple studies have shown that blue light blocking glasses can improve sleep quality and sleep duration while making it easier to fall asleep.
Q: What will blue objects look like when using blue light glasses?
A: True blue objects will appear black, while lighter shades of blue will look like various shades of grey when wearing blue light blocking glasses. Other colors, like green, yellow, orange, and red will appear as they are.
Q: How do you clean blue light glasses?
A: Most manufacturers recommend using mild dish detergent and a soft cloth to clean your blue light glasses. Alternatively, you may want to use traditional eyeglass cleaner and a microfiber cloth. The, like most things, depends wholly on the specific brand of your blue light blocking glasses.
Q: What’s the difference between blue light glasses and blue light apps or software?
A: Blue light apps, software, and night mode settings change blue colors to a reddish-orange. They simply reduce the amount of blue light on the screen instead of filtering the blue light itself. They can still be effective, although they can also make it difficult to view or read the screen.
Q: Do blue light glasses filter sunlight?
A: Yes, all visible light, including light from the sun, a smartphone, or lightbulb, contains blue light. Blue light glasses filter all blue light, and they don’t discriminate based on the source.
Q: Can you drive with blue light glasses on?
A: Yes, you can drive with blue light glasses on. This is unlikely to be affected by local traffic laws or regulations.
Q: Can you wear blue light glasses during the day?
A: Yes, blue light glasses can be worn during the day or night without problems.
Q: Does blue light from screens affect sleep?
A: Yes, evidence shows that blue light from screens affects sleep. Blue light keeps us awake. During the day, blue light from the sun tells our bodies to stay awake. At night, the lack of blue light tells our bodies to begin producing melatonin to prepare for sleep. When you use artificial screens at night, it disrupts melatonin and sleep.
Q: Do blue light blocking glasses prevent eye disease?
A: There’s no evidence that blue light blocking glasses prevent eye disease. Be cautious of any company claiming that their product can prevent eye disease.
Q: How do you prevent digital eye strain or computer vision syndrome?
A: Some people wear blue light glasses to prevent digital eye strain. You can also use something like the 20-20-20 rule, looking at least 20 feet away from your screen for 20 seconds every 20 minutes.
Q: Is blue light from screens harmful?
A: Most evidence shows that blue light from screens isn’t technically harmful, although it could disrupt sleep. Some studies, however, have shown that blue lights can increase the risk of age-related macular degeneration, eye disease, and even blindness, while other studies have shown no correlation.
Q: Can you wear blue light blocking glasses as sunglasses?
A: No, blue light blocking glasses are not designed to be worn as sunglasses, even though some block both UV radiation and blue light. They should not be used as a substitute for sunglasses.
Q: Can you wear other glasses underneath blue light glasses?
A: If your reading glasses or prescription glasses fit underneath, then there’s nothing wrong with wearing reading glasses or prescription with blue light glasses. Some glasses may warn against this, so consult your product instructions to be sure.
Q: What’s the difference between blue light blocking and blue light filtering glasses?
A: Filtering and blocking are often used interchangeably, although they technically refer to two different things. Blue light filtering glasses are clear (or sometimes slightly tinted yellow), while blue blocking glasses are typically yellow, amber, or red.
Q: Who should use blue light glasses?
A: Anyone can use blue light glasses from office workers to gamers to smartphone users. Nearly all forms of visible light emit blue light, meaning that nearly every consumer is influenced by the light on a daily basis.
Q: What is melatonin?
A: Melatonin is a hormone produced by your body to perform various functions. It’s known as the sleep hormone because it’s closely connected to sleepiness and sleep quality. Your body begins producing melatonin in darkness (say, after sunset).
Final Thoughts
Blue light blocking glasses have surged in popularity in recent years. For many people, a smartphone screen is the last thing they see before closing their eyes at night. Blue light from digital displays disrupts our sleep, and some evidence shows that blue light leads to health problems.
If you want to improve your sleep, consider buying a pair of blue light blocking or filtering glasses. They can reduce blue light and increase melatonin, helping you get a more restful sleep.
