Macular Degeneration Blue light (HEV) penetrates all the way to your retina and has been shown that too much exposure to blue light can damage light sensitive cells in the retina. This causes changes that are similar to those of macular degeneration, which can lead to permanent vision loss. Many eye care professionals have concerns that the blue light exposure from digital screens might increase a person"s risk of macular degeneration later in life.

Digital Eye Fatigue Short wavelength, high energy blue light scatters more easily than other visible light and makes it not as easily focused. When you"re looking at your digital screen that emit significant amounts of blue light, this unfocused visual light reduces contrast and can contribute to digital eye strain.

Sleep Disruption Blue light is very important in regulating circadian rhythm - your body"s natural wakefulness and sleep cycle. Exposure to blue light during daytime hours helps maintain a healthful circadian rhythm. But too much blue light late at night can disrupt this cycle, causing sleepless nights and daytime fatigue. People who use their electronic devices before bed have a harder time falling and staying asleep.

It"s well documented that some blue light exposure is essential for good health. Research has shown that high-energy visible light boosts alertness, helps memory and cognitive function and elevates mood.

In fact, something called light therapy is used to treat seasonal affective disorder (SAD) — a type of depression that"s related to changes in seasons, with symptoms usually beginning in the fall and continuing through winter. The light sources for this therapy emit bright white light that contains a significant amount of HEV blue light rays.

Also, blue light is very important in regulating circadian rhythm — the body"s natural wakefulness and sleep cycle. Exposure to blue light during daytime hours helps maintain a healthful circadian rhythm. But too much blue light late at night (reading a novel on a tablet computer or e-reader at bedtime, for example) can disrupt this cycle, potentially causing sleepless nights and daytime fatigue.

If you love round lenses and want something with a hint of flair, the Sojos Cat Eye Blue Light Blocking Glasses are for you. These minimalist, wire-framed glasses have the tiniest cat-eye curves that let you experiment with a fun design without committing to an elaborate shape. They cost $17 (at the time of publication) and come in five metal-framed options; the lenses are nearly colorless, so you can remain productive on your computer without being distracted by an orange-tinted screen. More durable than most other metal-framed pairs we tested, the Sojos also have extra-thin arms that flex farther than those of most glasses we found, which makes them very comfortable and easy to wear. If you’re prone to sweating, you may also find that metal-framed glasses with nose pads, like the Sojos, are less likely to slide down your face than an all-acetate pair such as the Tijn.

The Sojos were one of the few pairs of glasses that didn’t trigger migraines in our tester who suffers from them, which, while anecdotal, is still a thing to keep in mind if you’re prone to headaches.

The Sojos Cat Eye glasses are sold in five different colors to suit your tastes (but they’re available in only one size). Thanks to Amazon’s friendly return policy, you have 30 days to send these back if they’re not your style. And while the incredibly light orange lens tint is barely noticeable to the naked eye, the lenses do have a film-like quality, which can make them appear foggy at times. The Sojos are the only pair we tested that comes with a repair kit, a microfiber cleaning cloth, and a storage bag.

The Tijn Classic Nerd Square Blue Light Blocking Glasses are great for people who like to match their frames to their outfit. These glasses are sold in more than a dozen different translucent colors and patterns, from sea green to leopard, more than any pair we tested. The classic square frames didn’t overwhelm our testers’ faces, and the plastic is durable and doesn’t twist. They’re sturdy, with level arms that sit flat on your face, and unlike half the pairs we tested (including the similar WMAO Blue Light Blocking Glasses), they don’t suffer from overly stiff hinges. These lenses aren’t completely colorless—they have a very faint orange tint—but our testers didn’t mind. “I had forgotten that they were on my face,” said Wirecutter"s Justin Krajeski. Our panelists also said these glasses were comfortable to wear because the nose bridge and temple arms didn’t pinch, unlike some of the other glasses we tried. The Tjins do weigh more than half the pairs we tested—0.9 ounces. But if they’re uncomfortably heavy, you can return them to Amazon.

Offering both prescription and non-prescription blue-light-blocking glasses, EyeBuyDirect is our pick for the best place to buy glasses online thanks to its selection of high-quality glasses and reliable customer service. (It also offers a 14-day return policy.) We tried only two styles, but EyeBuyDirect sells hundreds of pairs in a variety of shapes, colors, sizes, and prices, and it can add an anti-glare coating to make those marathon Zoom sessions slightly more bearable.

EyeBuyDirect’s blue-light lenses are sold in four tiers and can be applied to both prescription and non-prescription glasses. We paired our frames with the cheapest blue-light lenses, at $19, which have a slight orange tint that was darker than half of the glasses we tested. You’ll need to upgrade if you want true colorless lenses, premium anti-glare coating, or magnification for reading.

We tested two frame styles: the Escape Rectangle Eyeglasses and the Botanist Rectangle Eyeglasses (though Wirecutter"s Tim Barribeau also likes his pair of Carnival frames with blue-light-blocking lenses). The Escape frames are timeless and available in a variety of patterns and colors, from the modern clear acrylic to the matte tortoiseshell. The subtle silver hinge studs along the edge add a hint of flair to the frames without pulling attention away from your face. They come in small and medium sizes, so they’ll fit on a wider variety of faces than any of the other glasses we recommend.

At just 0.5 ounces, the Botanist frames are the lightest pair we tested—most pairs we tried ranged in weight from 0.8 to 1.2 ounces. They’re better for people with smaller faces, and while they’re available in only one size (medium), the narrow frame and rectangular lenses make them smaller than the medium-sized Escapes. The Botanist frames also offer more unique color options, including a striped navy finish, black with marble temples, and a wood-effect finish.

Overall, EyeBuyDirect’s quality is better than any off-the-rack brand we found, and if you don’t like the pairs we tested, the company sells hundreds of frames in multiple colors and sizes. You can even search by size, using a current pair of glasses as a fit guide. And unlike our other recommendations, EyeBuyDirect is the only retailer that sells truly colorless lenses, albeit for an additional fee. If your glasses don’t fit or flatter, take advantage of EyeBuyDirect’s 14-day, no-questions-asked full refund policy.

Imagine light passing through a prism, which fans it out into the colors of the rainbow. Each color you see is part of the visible light spectrum, which is defined by wavelengths. Shorter wavelengths (the smaller numbers on the chart above) generally become more harmful as they decrease, which is why many people want to block too much blue and violet light from reaching their eyes. However, it’s not a good idea to banish blue light completely. It’s found in every light source, including sunlight, and is known to boost your attention and mood. Long-term effects on eye health are unclear, but some studies have shown that rat retina cells die when exposed to extreme levels of blue light.

Blue light plays a major part in controlling your sleep cycle. Too much of it—even everyday levels, if you spend a lot of time in front of a screen—has proven problematic. Daylight, which contains blue light, helps tell your internal clock when it’s time to start the day or hit the hay. Stare at a blue-light-emitting device for too long at night, and your body might think it’s still daytime. Blue light, especially, has been found to suppress melatonin for about twice as long as green light. That could mean the difference between falling asleep in 30 minutes and one hour. During the day, such exposure to blue light can help keep you alert, but in the evening hours it can be potentially problematic (which is why many devices have nighttime modes that turn the screen that yellowish hue).

Lack of sleep affects every part of our body, our sleep experts told us. It can impact your heart, cognitive skills, and immune system, as well as lead to diabetes—and more. “It’s like rust in your car,” said Dr. Chris Winter, a neurologist and a sleep specialist. “It’s never a good thing, even if you’re not seeing it happening in real time.”How we picked and tested

To find some stylish pairs of blue-light-blocking glasses, we scoured both prescription and non-prescription online sellers, Instagram influencer feeds, and forums. We also asked our friends, family, and colleagues for their chicest recommendations. We found 22 over-the-counter pairs with plastic or wire frames, ranging in price from $2 to $30. We narrowed down our testing pool by reviewing the frame styles, materials, color choices, brand reputation, third-party reviews, and prices. We also considered frames from brands we recommend in “The Best Places to Buy Glasses Online.” And we preferred lenses that were described as colorless or nearly colorless, as opposed to dark-orange polarized lenses.

For this guide, we had three people test 13 pairs of glasses while working on our laptops and scrolling through (“liking”) our friend’s social feeds on our phones. We paid special attention to style, quality, fit, comfort, and lens glare. Some glasses seemed comfortable at first but felt too heavy or tight after a few hours. Some had distracting glares that suddenly became very noticeable during a video call. We steered clear of glasses with easily scratched lenses, twisted arms, and rigid hinges (and there were a lot).

Many online resources that suggest you can test blue-light-blocking glasses at home with DIY tricks, such as looking at some overlapping blue circles on your screen or shining a light through the lenses onto photosensitive paper. We tried these methods, but we couldn’t find any difference between the pairs we tested and, short of a $5,000 spectrometer, there’s no way to know for sure how any particular pair will perform. The best way to determine whether a pair of glasses will work for your eyes is to try them (and be willing to return them, if necessary).

Our research also showed that price doesn’t necessarily guarantee effectiveness. A July 2019 study in Optometry and Vision Science found no correlation between price and advertising claims when comparing the efficacy of cheap ($3), medium ($40), and high-end ($350) blue-light-blocking glasses and sunglasses,so don’t assume you’re getting stronger blocking ability by spending more. “There’s not a lot of rigorous standardization with the lens manufacturers themselves,” said Dr. Sunir Garg, clinical spokesperson for the American Academy of Ophthalmology (AAO) and a professor of ophthalmology at the Retina Service of Wills Eye Hospital. Many retailers sell lenses with a blue-light-blocking filter that can scratch and fade over time, though prescription retailers usually have higher standards and bake the blue-light technology into the lens resin. If you’re curious about blue-light-blocking glasses, we think it’s smart to start with a cheap pair to see if you notice a marked improvement in your sleep or less eyestrain (although there’s no guarantee). You can always upgrade to a longer-lasting pair later.

When you’re ready for an upgrade, The Vision Council, which represents optical manufacturers like EyeBuyDirect and Zenni, said buying prescription glasses from a professional with medical-grade blue-light-blocking lenses is the safest bet. And if you want to confirm the results for yourself, you can ask them for a spectral report, which details how much light and at which wavelengths their lenses actually block.Do blue-light-blocking glasses work? Kind of.

We read nearly two dozen studies and position statements on blue-light-blocking technology, and interviewed three optometrists, two eyeglasses providers, two sleep specialists, a medical doctor, and an ergonomics expert. After all of our research, we still couldn’t definitively answer this question (we looked into it years ago and came to a similarly uncertain conclusion). It’s more useful to consider what you’re using blue-light-blocking glasses to achieve.

Blue-light-blocking glasses are worth a shot if you find yourself tossing and turning after spending hours in front of screens, especially if you’re doomscrolling on your phone. The blue light emitted by these devices tells your body to stay awake when you’re actually supposed to be winding down to go to bed. Glasses that block a percentage of the blue light your eyes absorb can prevent you from having trouble falling asleep.

You don’t actually need to spend money on a new pair of glasses to decrease the blue light you see, though. Both the AAO and the American Optometric Association (AOA) advise reducing the amount of time you spend on your digital devices at night, avoiding bright screens up to three hours before bedtime, and dimming your screens and setting them to night mode so you’re exposed to warmer colors as you unwind. (Here’s how to adjust those settings on an Apple iPhone and a Samsung Galaxy.)

Of course, that’s easier said than done, and you’ll still be exposed to the blue light emitted by various household items other than your phone or computer. The benefits of blocking blue light to fall asleep do improve when you add a pair of glasses, said Roy Raymann, then chief scientific officer of SleepScore Labs, because they’re designed to block all sources of blue light, such as your bedside lamp, television screen, and refrigerator light bulb. Personally, I’ve found a combination of these two strategies to be beneficial. Using prescription lenses with blue-light-blocking technology and setting my devices to night mode with a color filter has helped me fall asleep faster in recent weeks.

Eye experts say the low levels of blue light from your computer screen probably aren’t making your eyes tired and achy—it’s more likely that while intensely focusing on your screen, you blink less, resulting in dryer eyes. This can lead to digital eyestrain, and potentially blurry vision, dry eyes, and headaches. It’s similar to how you might feel after periods of intense focus, such as reading a book or handwriting your pandemic-themed memoir.

Proponents of blue-light-blocking glasses point to another eye-health concern: age-related macular degeneration, which happens when the macula part of your retina (the central area of the back of your eyeball) is damaged. According to the AAO, it’s the leading cause of vision loss among people 50 and older. Recent studies show that extremely high levels of blue-light radiation may increase the risk for age-related macular degeneration, but the AAO, the AOA, and the UK’s Association of Optometrists all state that blue light from digital devices doesn’t cause adverse effects. Blue-light-blocking glasses may help lessen the risk of age-related macular degeneration, but for now the evidence isn’t definitive.

If you suffer from tension headaches or chronic migraines, as I do, don’t expect a cheap pair of glasses to help. During testing, I found that some of the blue-light-blocking glasses actually caused more migraines than they prevented, and it had nothing to do with the lenses.

As Garg suggested, you’re better off taking frequent breaks to look away and relieve your eyes. You can also try adjusting your ergonomic setup. Thomas Caffrey, an ergonomics consultant for The New York Times, said the placement of everything from your computer monitor to your keyboard can cause digital eyestrain or headaches. Poor posture can actually cause “referred pain,” which is when an injured area causes symptoms elsewhere. Check out our advice in “7 Things You Need for an Ergonomically Correct Workstation”—if you still experience headaches after making those adjustments, our experts suggest consulting an eye-care specialist.What to look for in blue-light-blocking glasses

Then consider the lens color. All of the glasses Wirecutter tested appeared to be colorless at first glance, but when we wore them, we noticed they all have a faint to moderate orange tint. (For an extra fee, you can order prescription lenses that are virtually colorless from our favorite online retailer, EyeBuyDirect.) Orange lenses block blue light because they only let through light with similar wavelengths, like orange and red. The stronger the orange tint, the less blue light gets through, decreasing the amount your eyes are absorbing and potentially helping to counteract negative effects. (Keep in mind that colored lenses can affect the color accuracy you see on your screen.)

If you plan to wear them throughout the day, don’t pick lenses that are too dark orange or those that claim to block 100% of blue light. The AOA doesn’t recommend these. “The eyes still need blue light, both physiologically and for color perception,” said Dr. William T. Reynolds, president of the AOA. “Newer lens technology blocks only a portion of the blue light. These lenses are practical because they remain clear and still offer blue-light protection while reducing glare.” (You can get a sense of how dark the tint is by reviewing the product description and third-party reviews.)

However, if you don’t care about looks and plan to wear them only right before bed, a quality pair with a much darker tint may be better for your sleep cycle. “They’re not something you want to go out in public wearing, but they work,” said Winter, the neurologist. He recommends both this UVEX pair and Swanwick’s line of blue-light-blocking glasses.Who needs blue-light-blocking glasses?

Eye-care professionals are quick to point out that there’s no one-size-fits-all solution when it comes to your eyes. If you’re considering blue-light-blocking glasses, it’s best to schedule an eye exam with your eye-care provider for the best treatment option. For people experiencing headaches after spending all day at a desk, it may be their ergonomic setup that is to blame, or perhaps just general eye fatigue. For others, it could be that their vision has changed and they need a new prescription.

Parents with children in remote programs may be tempted to buy a pair of blue-light-blocking glasses for their kids, but most children shouldn’t be wearing them all day. In fact, their eyes actually need that wavelength from sunlight—a deficiency of natural blue light in maturing eyes can lead to myopia (nearsightedness). “It’s really a tough time for parents, and they’re looking to do right by their kids,” said Garg. “But we’re not seeing it being a clinical concern. We’ve naturally evolved to take in as much as we need.” (Garg’s own child is in a virtual learning environment, and he’s not worried about their exposure.) To help protect a child’s eyesight and ensure they’re receiving the developmental benefits of natural blue light, make sure they’re getting one to three hours of outdoor playtime a day, said the AOA’s Reynolds, and try to limit their screen time and exposure to bright lights before bed (for better-quality sleep). Here’s some age-based screen-time guidance from the World Health Organization.

The role blue light plays on human sleep patterns is well established, so experts say a pair of blue-light-blocking glasses can help adults snooze better. The best way to achieve a better night’s rest is by using blue-light-blocking glasses at night and reducing screen brightness and exposure before bedtime. “Those things definitely make a difference,” said Winter. “Even a dimmer switch for your home can help.” As for both daytime and evening use, our experts said the science is still out on whether wearing blue-light-blocking glasses all day will be beneficial or detrimental to long-term health.

Blue-light glasses may even help you sleep better if you have limited vision or a complete loss of sight, though it’s best to consult your doctor. For some, these glasses could help improve sleep, Winter noted, because blue light can still affect how some people with color blindness secrete melatonin. Similarly, people who are blind can experience significant disruptions to their sleep because the light pathway in the eye is still absorbing blue light, even though the visual pathway can’t see it.The competition

The temple arms of the K Kenzhou Blue Light Blocking Computer Glasses have loose hinges, and the glasses regularly slid off in our testing. The nose pads also pinch (and gave one tester a headache).

The stylish Sungait Cat Eye Blue Light Glasses seemed promising, but the frames are crooked, the temple arms are too tight, and the moderate orange tint and white lens reflection were distracting come work time. The combination of design failures gave one tester a headache after wearing this pair for just 30 minutes.

The cheap Wild Fable Women’s Blue Light Filtering Rectangle Glasses from Target offer fun, transparent frame hues, but the glasses themselves are crooked, the hinges are too tight to easily open and close, and the moderate orange tint and blinding purplish reflection made this pair annoying to wear.

The WMAO Blue Light Blocking Glasses are crooked, yet they stayed on better than most plastic frames we tested. Unfortunately, one tester still got a headache while wearing this pair.

The Cyxus Blue Light Filter Computer Glasses have tight hinges that are difficult to open and close, the temple arms pinch, and the nose pads are loose and sit farther down than most glasses we tested, which made them uncomfortable to wear. These glasses also gave one tester a headache.

The Free People Rion Blue Light Glasses (no longer available) reminded us of frame styles that were popular in the 1980s, but not in a good way. Also, the glasses are crooked, the nose pads sit low (like those of the Cyxus pair), one of the lenses was cracked, and the hinges are uneven.

The Urban Outfitters Logan Half-Frame Blue Light Glasses (no longer available) weigh 1.2 ounces, making this the heaviest pair we tested—too heavy to wear for long periods of time.

The Urban Outfitters Taylor Blue Light Round Glasses (no longer available) were a former pick that we liked for their lightweight design and subtle but attractive color options.FootnotesFrequently asked questions

No one can definitively say if blue-light glasses really work—they do block some blue light, but it’s unclear how helpful that is. It’s better to consider why you need a pair and go from there. Generally, people use blue-light-blocking glasses to get a better night’s sleep, reduce digital eyestrain, or prevent headaches.

Blue-light glasses block a percentage of the blue light your eyes absorb, so wearing a pair at night might help you fall asleep faster by telling your internal clock it’s time to rest.

Unfortunately, blue-light glasses most likely have no effect on preventing digital eyestrain or headaches. Your eyes are tired because you’re intensely focusing on your screen and blinking less, resulting in dryer eyes, blurry vision, and headaches. Using artificial tears and taking frequent breaks can help mitigate those issues.

Probably not, but that doesn’t mean you should wear them all the time. The medical community doesn’t believe blue-light glasses can damage your eyes but, most adults shouldn’t wear these glasses outdoors or 24/7 because your eyes still need to absorb natural blue light from the sun to tell your internal clock when it’s daylight (time to wake up) or nighttime (time to rest).

Similarly, most children shouldn’t be wearing blue-light glasses all day. Their eyes actually need that wavelength from sunlight because a deficiency of natural blue light in maturing eyes can lead to myopia (nearsightedness).

Eye-care professionals are quick to point out that there’s no one-size-fits-all solution when it comes to your eyes, but in our research and testing, the most compelling use case for blue light glasses is to help you if you have trouble falling asleep at night. If you’re considering blue-light-blocking glasses, it’s best to talk to your eye-care provider first. If you have headaches after spending all day at a desk, it may be an ergonomic setup that’s to blame, or perhaps just general eye fatigue. For others, it could be that their vision has changed and they need a new prescription.

Adults who have trouble falling asleep may benefit from a pair of blue-light-blocking glasses. Combine the glasses with reducing your screen’s brightness, and limiting your exposure to other sources of synthetic blue light, like your bedside lamp, for maximum effectiveness.

Kids shouldn’t wear these glasses, even those who are enrolled in distance learning, because their eyes need the blue light found in sunlight to prevent their maturing eyes from developing nearsightedness.

Eye experts say the low levels of blue light from your computer screen probably aren’t the thing giving you a headache, so blocking them won’t help by much. Instead, the root cause is more likely that while intensely focusing on your screen, you blink less. This can lead to digital eyestrain, and potentially blurry vision, dry eyes, and headaches. It’s similar to how you might feel after periods of intense focus, such as reading a book.

In our testing, our reviewer who suffers from tension headaches and migraines said the blue-light-blocking glasses actually caused more migraines than they prevented, and it had nothing to do with the lenses. Bad glasses with tight frames, pinching nose pads, or acute light reflections may worsen your headache symptoms, rather than relieve them.

No, standard eyeglasses do not block blue light. You can purchase glasses with a blue-light blocking coating for an extra fee. EyeBuyDirect sells lenses with blue-light coating starting at $19.

You can clean blue-light-blocking glasses like any pair of lenses with these steps: Remove any visible gunk with a cotton swab; rinse the glasses under warm water to dislodge excess grime; squirt a pea-sized drop of dish soap onto the lenses and rub the soap in with your fingers; rinse off the soap; shake the glasses dry; and wipe them down with a microfiber cloth. Our post on How to Clean Your Glasses offers a little more detail.Sources

Forito sells blue light screen protectors and ranks as a best seller on Amazon. The brand makes screen protectors for laptops and desktop computers and claims it is a leading screen filter manufacturer.

Forito claims to use the newest blue light filtering technology. The company also states that its screen protectors are anti-static, anti-glare, and anti-scratch. They can also block 100% of UV-400 rays and protect against radiation.

EYES PC offers a range of different blue light screen protector panels. These products are compatible with laptops, desktop computers, large monitors, and television screens.

This brand sells screen protectors in sizes ranging from 11-in laptop panels to panels large enough to fit a 65-in television. They are 2 millimeters (mm) thick.

EYES PC also claims the product’s test data meets Food and Drug Administration (FDA)-accepted American National Standards Institute (ANSI) Z80.3 test standards.

This VizoBlueX is available in different monitor sizes. It promises to maintain the full-color spectrum visibility while blocking up to 100% of blue light to reduce eye fatigue and improve sleep.

It claims to protect the eyes from harmful UV and blue light — up to 99% between 300 and 400 nanometers (nm) and up to 54% between 400 and 470 nm. It also promises headache relief, better sleep, and reduced glare and reflections.

Aside from protecting against blue light and UV, the brand says this tempered glass product provides five times more protection than a typical plastic screen protector. It includes installation instructions, a 2-year warranty against scratches and damages, and free shipping.

In our modern world, people spend more time than ever in front of screens. In fact, nearly one-third of adults report being online almost constantly throughout the day. Despite its many advantages, this explosion in digital gadgets also comes with a price. Your computer screen, tablet, and smartphone all emit high-energy blue light similar to the sun. When you use these digital devices into the late hours of the evening, the blue light exposure can disrupt your sleep-wake cycle.

To combat the effects of screen time before bed, more and more companies are offering glasses with special lenses that can block blue light from reaching your eyes. These blue light blocking glasses offer a safe and drug-free way to make sure late-night screen time and artificial lighting don’t affect your sleep.

Blue light blocking glasses are a fairly new type of technology, and the industry lacks a clear set of regulations to guide shoppers. Whether you’re a gamer or just need to get some work done on your computer before bed, we’ll help you sift through the marketing claims to find the best pair of blue light blocking glasses for your needs.

EyeBuyDirect (EBD) takes an unconventional approach to blue light blocking glasses. Customers can choose from more than 1,400 different frame styles, then select the type of blue light blocking technology they’d like for their eyewear depending on their preferences and needs.

EBDBlue Plus technology includes advanced blue light blocking, UV protection, an anti-static layer to safeguard the glasses from dust, and a lens coating to reduce smudging. EBDPlus 360 builds on this by offering the same features as EBDBlue Plus as well as a special coating that minimizes reflections by as much as 50% during the day. The innovative EBBBlue Smart option enables the lenses to automatically adjust based on natural light and darkness levels. Lastly, SightRelax glasses have a slight magnification at the bottom of the lenses to improve vision and ease discomfort for gamers, E-readers, and other people with screen-centric lifestyles, as well as employees and students who spend most of their day using a computer.

The Ocushield Anti Blue Light Glasses are comfortable and lightweight yet highly effective at protecting your eyes. The lenses are designed to block up to 99% of UV rays and blue light emissions with wavelengths that fall between 300 and 400 nanometers (nm), as well as 40% of emissions in the range of 400 to 470 nm. This makes them well suited to late-night workers and other people who need to use electronic devices before bed.

Felix Gray offers a wide range of frames for blue light glasses. Each of the brand’s 17 adult-friendly styles are designated as narrow, medium, and/or wide, so you can make a selection based on what will fit most comfortably. Four of the frames are designed for “low bridge” noses that sit below the pupils. You can choose between clear or amber lenses depending on your personal preference, and most of the frames are available in at least two to three different colors.

The Nash, Roebling, and Faraday designs are also available in kid sizes for age ranges of 4 to 8 years or 9 to 13 years. The lenses for every Felix Gray style have been treated with a proprietary anti-glare coating intended to reduce blue light exposure by as much as 98%. You can arrange for the glasses to match your existing prescription. Most styles are also available as reading glasses.

While blue light blocking glasses can improve your melatonin levels and help you sleep soundly, it’s important to note that some blue light is essential for a balanced sleep-wake cycle. The Day Swannies from Swanwick are designed to block wavelengths ranging from 400 nm to 450 nm, which is considered the most harmful range across the blue light spectrum. Wavelengths between 450 nm and 500 nm pass through the lenses, keeping you alert as you go about your day without incurring too much blue light exposure.

People who typically use computers, tablets, and other screen devices for their profession are great candidates for the Day Swannies. The lenses are fairly clear, and aren’t as tinted as many of their counterparts on the market today. This makes the glasses less suitable for nighttime use — Swanwick sells a separate “orange lens” collection with stronger blue light blocking capabilities — but you can wear them throughout the day as you use electronic devices. Each pair is equipped with a pair of spring hinges, giving the frame a flexible feel.
