Circadian Rhythms | Do Blue Light Blocking Glasses Work | Dr. J9 Live

While blue light blocking glasses are effective at reducing the amount of blue light that enter the eyes, there is no current research to suggest that this can improve or protect the health of your eyes. Put simply, there is no scientifically-proven benefit of wearing blue light blocking glasses for your eye health.

As The College of Optometrists states: The best scientific evidence currently available does not support the use of blue-blocking spectacle lenses in the general population to improve visual performance, alleviate the symptoms of eye fatigue or visual discomfort, improve sleep quality or conserve macula health. 8

So Do Blue Light Blocker Glasses Work

Yes, blue light blocker glasses do work. But to find out if your blue light protection glasses work, theres a simple yet effective test you can do.

While wearing the glasses, look at something you know will have a blue light, like the flashing lights on top of police vehicles or ambulances. If you cant see the blue light flashing, your glasses have an effective blue light filter lens.

However, be aware of the color of your new blue-light-blocking lenses. Glasses with a blue tint make everything look blue, so the blue light wont be noticeable. Computer glasses with clear lenses block about 20% of blue light , which can be enough to limit the harmful effects of blue light. Better blue light blockers have yellow, orange, or amber lenses. Red lenses can block almost the entire blue light spectrum, but can also affect your color vision.

Myth # : Blue Light Blocking Glasses Can Damage Your Eyes Because They Make You Dependent On Them

Blue light blocking glasses are used as a measure of protection against excessive blue light when working with screens or exposed to artificial lighting during the day and late at night.

Specifically designed clear lens daytime computer glasses filter only the unnatural blue light coming from screens and fluorescent lights. They allow the natural range of rays to pass through responsible for feeling happy, awake, and alert. Ensuring you have a set of daytime blue light glasses that filter blue light down enough and target the correct wavelengths is very important, not all blue light glasses are created equal so do your research before investing!

If you wore night-time red / orange tinted glasses during the day it there would be a possibility that your eyes become sensitive to blue light. More importantly you would also start to create circadian mismatch where the brain will think its night-time during the day. Blocking too much blue light during the day would be just as bad as you as too much blue light a lack of blue light during the day is linked to low mood, low energy and fatigue. So its smart to wear night-time tinted glasses after sundown, and keep a pair of quality clear lens computer glasses for the day!

Should You Try Blue Light Blocking Glasses

While there is some evidence that blue light glasses can keep your screen time from messing with your sleep, theyre unlikely to relieve digital eyestrain symptoms altogether and wont protect against macular degeneration.

None of this has stopped some doctors from touting them. Boots Opticians in the United Kingdom was fined about $56,000 for overstating claims that blue light lenses help prevent eye disease, according to Optometry Today.

Some people swear these glasses offer relief, however. And if they work for you, go for it. Theres likely no harm, according to Baylor College of Medicine. If you get a benefit or feel more comfortable wearing them, then wear them, Frempong says. Theyre certainly not going to hurt you, but theres no evidence that theyre helping you.

Blue Light Blocking Glasses For Kids

Just like adults, kids and teenagers are using screens more both at home and at school in many cases much more than adults. They are just as susceptible as adults are to the damage blue light can cause.

Kids will spend more of their lives looking at screens than any generation before them. Since damage from blue light is cumulative, kids blue light blocking glasses or blue light blocking lenses on their prescription glasses can help them just as much as, if not more than, adults.

If your child already wears glasses, adding a blue light blocking coating can be an easy way to help with circadian rhythms, and eye fatigue and strain.

If your child doesnt wear glasses, they may enjoy picking out and wearing stylish kids blue light blocking glasses. But if your child doesnt like wearing glasses, you can try blue light screen filters that fit over monitors, phones or tablets.

What Does Blue Light Do To Your Eyes

Blue light has a short wavelength, which makes it very easy for it to penetrate the eyes. This means that almost all visible blue light rays can pass through the cornea and lens to the retina . While there is little research to support this, some experts have suggested that too much exposure to blue light has the potential to damage the light-sensitive cells in the retina. One animal study also found that blue light damage may cause phototoxic retinal damage.1

However, while it is true that digital screens do emit some blue light, research has found that the level of blue light exposure from screens is significantly lower than that from natural daylight and neither levels approach eye safety limits.2 This means that the potential blue light damage caused from digital screens is likely to be very little, if any at all.

How Does Blue Light Affect Sleep

When the sun goes down, the lack of light signals our bodies to start producing melatonin, the hormone responsible for making us fall asleep.

Before the advent of artificial light, the sun regulated our sleep schedules. But today, we’re exposed to light all day and into the night. While exposure to any light waves after dark delays our bodies’ production of melatonin, blue light waves can be especially problematic because they keep us alert.

On the other hand, blue light can help us overcome sleep issues by disrupting our usual circadian rhythm. The Lumos mask, for example, uses light therapy to mitigate the affects of jet lag.

Ask an Expert: Do Blue-Light-Blocking Glasses Help with Sleep?

In our Lab test, we identified 20 pairs of blue light blocking glasses worth noting, but only included 10 on our final list of recommendations. The remaining pairs of glasses seemed to reduce much of the eye strain associated with blue light, but our testers found that fit and comfort varied widelythey were too big, too tight, too looseand that, often, these glasses had tinted lenses .

  • : Our testers thought the fit of these glasses was comfortable and the clarity was excellent, but the lenses themselves were so oversized, they made us look goofy.
  • : These glasses reduced glare exceptionally well and were super comfy, but again, our testers found them to be too large and oversized.
  • : We thought these glasses were comfortable to have onuntil we had to look at a computer screen, at which point the yellow tint was distracting and interfered with our clarity of vision.
  • Felix Gray Turing Glasses at Our testers thought these glasses were cute and stylish, along with providing a clear line of sight, but they were so small and tight-fitting they were painful to wear.
  • : These glasses were affordable and on-trend, but nowhere near as well-made as the other glasses on this list, per our testers, and the tinted lenses made their use extra uncomfortable.

Are Blue Light Glasses Good For Night Driving

If you’re having issues with night driving, this is a different issue to using blue light blocking glasses to filter out blue light from screens

“At night there’s more contrast in the light so we’re really talking about contrast sensitivity here,” says Dr Sachdev, “and there’s no evidence that blue light glasses will help with night-time driving.

“Generally, we find there’s often an organic cause for night-time driving difficulties, such as cataracts, that people don’t realise they’ve got. So if you’re having difficulties driving at night you need a full ocular examination to rule out any issues that may be causing it.”

Can Blue Light Glasses Help With Eye Strain

It may surprise you, but many eye issues that are caused by digital screens arent due to blue light.

Dr. Bajic says many people experience eye discomfort from digital screens, but most of the issues actually fall under a term called computer vision syndrome . Some symptoms include:

  • Hard time keeping your eyes open.

CVS is a broad range of eye strain and discomfort issues. Your eyes are constantly shifting focus and moving while looking at the screen. Plus, the glare and contrast can be tough on your eyes. So, although you may be experiencing eye irritation from a long day working on your computer, your eye discomfort is not directly from the blue light itself.

When we stare at a digital screen or device for too long, were not blinking as often as we normally would, which causes the cornea to become dry and irritated, says Dr. Bajic. When we focus our eyes on something close up, like a screen or even a book, our eyes are strained and contracted, which can cause eye discomfort. But if you look ahead to a distant object, our eyes relax.

Myth#: Blue Light Blocking Glasses Can Damage Your Eyes If You Get Them Without Prescription

This myth is entirely unfounded. If your eyesight is not weak, you can buy blue light blocking glasses without a prescription. If you usually wear contact lenses to correct your vision, you can wear blue light glasses as usual with no issues.

However, if you usually wear prescription glasses or reading glasses, you can take a look at Screentime Fitover computer glasses for the day and the NightFall Fitover glasses for night, which fit over your usual glasses and provide protection.

We strongly recommend against purchasing blue light glasses for either day or night-time that have reading or prescription lenses installed into them this is because the blue light blocking and filtering technology will filter blue light all the time even when you dont need it. When you are not being exposed to artificial light you do not want any blue light filtering to be applied, this is because natural blue light has so many benefits, therefore ensuring your not filtering out natural blue light is very important. Using prescription or reading blue light glasses means you will filter good natural light if you wear them all the time. Using fitover blue light glasses over your existing reading or prescription glasses provides you the blue light protection when you need it, and when your not looking at screens or under artificial light you dont have them on so you can get as much natural light as possible + they are much more affordable!

How We Picked And Tested

Blue Blocking Glasses

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 our friends 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 .

The Bigger Issue Of Eye Strain

According to data from DataReportal published in March 2022, the average American spends 7 hours and 4 minutes in front of a screen every day.

If youve felt like your eyes were bugging you after hours in front of a computer or other screen, you may have experienced digital eye strain. Digital eye strain is also known as computer vision syndrome, or CVS. estimates that 90% of people who use digital devices experience symptoms of digital eye strain, including:

  • Pain in the shoulders, back, or neck
  • Trouble focusing between near and far
  • Discomfort or strain in the eyes
  • Difficulty keeping eyes open

The severity of your symptoms will depend largely on how long youve been using the digital device. Underlying eye conditions will also have an effect, as will other factors such as glare on the screen from overhead lights.

Fortunately, the symptoms of digital eye strain or computer vision syndrome are usually temporary, and will soon subside when you stop using your devices. Sometimes, its possible for symptoms to continue for a while after that.

Pandemic Screen Time: Will Blue Light Glasses Help

As people in lockdown spend more time staring at laptops and other digital screens, theyâre ordering more blue light glasses, despite a lack of conclusive evidence the glasses actually reduce eyestrain or protect from the effects of blue light.

The optical company Zenni says sales for the blue-light-blocking product Blokz have risen 60% annually for the last 2 years, with nearly 2 million pairs sold in 2020 alone.

The glasses were already popular with office workers and gamers, âbut most certainly the pandemic has had a pronounced effect with nearly everyone absorbing more and more digital blue light than ever before,â says Sean Pate, a brand marketing and communications officer for Zenni.

The Book Club eyewear company says sales for its blue light glasses through March and April 2020 rose 116% over the same time in 2019, with the surge continuing, according to The Business of Fashion.

âYou never predict a moment like is the moment that a brand blossoms and all of a sudden starts to sell out and gain attention,â says creative director Hamish Tame.

360ResearchReports, a market research company, says the global market for blue light eyewear will increase to $28 million by 2024, up from $19 million in 2020. The advertised benefits of the glasses include less eyestrain, improved sleep, and prevention of eye disease.

But do they really work? It depends on who you ask.

But some eye professionals believe they have benefits.

Can I Wear Blue Light Glasses All The Time

Do BLUE LIGHT GLASSES work? – Fact or Fiction

Now that you have a better understanding of how blue light blocking glasses can protect your eyes and reduce uncomfortable symptoms, youre probably wondering how often you can wear them. Can you wear blue light glasses all day, or should you only wear them at certain times?Blue light blocking glasses are safe for all-day use, however, that might not be necessary. Its important to understand that blue light isnt inherently bad for you. The biggest source of blue light comes from the sun and a small amount of this natural form of blue light is needed for good health. It regulates your circadian rhythmthe bodys natural wake and sleep cycleand boosts alertness, memory, cognitive function, and mood.

The issue is, modern-day humans are exposed to excessive blue light due to spending long periods of time looking at digital screens at a close distance. Prolonged exposure to artificial blue light from screens has been shown to disrupt your circadian rhythm and cause symptoms like headaches and dry eyes. Blue light glasses are very helpful when it comes to guarding against artificial sources of blue light that deliver excessive amounts of this wavelength to your retinas. Theyre especially beneficial when using screens at night, as exposure to blue light at nighttime can easily disrupt your sleep.

The Best Blue Light Glasses According To Health Experts

If you decide to give them a try, Dr. Hau recommends finding a pair with anti-glare lenses. You can easily find options with a quick Google search. Warby Parker sells blue-light-filtering lenses, which can be added to any frame for $50. Brands like Target and J.Crew sell blue light glasses for about $10, while options from Look Optic and Felix Gray cost around $65 to $95.

Theyre not regulated by the U.S. Food and Drug Administration, however, so it can be difficult to know if youre getting a quality pair. Hau says to visit an optical shop that has an optometrist or ophthalmologist working on-site. They should be selling legitimate products, she says.

Dr. Branchini adds that though research so far doesnt show a benefit to these glasses, that could change in the future as more studies are conducted. I dont routinely recommend them because I dont think its been well demonstrated to have much benefit, Branchini says. That being said, the jurys still out. We dont really know for sure.
