Uv Light & The Importance Of Good Sunglasses
We all know that gloriously sunny days come with risks. The sting of a sunburn and the increased risk of skin cancer are well known but the danger to our eyes and vision shouldnt be overlooked. Yes, put on sunscreenbut dont forget a good pair of sunglasses! Learn more about UV light, where it comes from and how you can protect yourself.
Can I Use Computer Glasses For Reading
It isnt recommended to use computer glasses, or blue light filtering glasses, for reading anything other than a digital screen, because thats what theyre designed for. Computer glasses help reduce digital eye strain which is a cause of long hours spent in front of screens which emit potentially harmful blue light. While they do have some similar features to reading glasses, its better to opt for readers for things like books and physical materials.
What Are Blue Light Blocking Glasses
As the name suggests, blue light blocking glasses are a type of eyewear with special lenses designed to filter out blue light.
Blue light refers to a specific wavelength in the visible spectrum. The visible spectrum encompasses all the light wavelengths that the human eye can see, including the entire rainbow of colors from red to violet. Among the visible colors, blue light has a relatively short wavelength and delivers high levels of energy to the eye.
Blue light is very common. When you go outside, your eyes are awash in blue light coming from the sun. Artificial sources of blue light are also ubiquitous in modern life. From fluorescent and LED lighting to all of the various screens we use, were frequently bathed in blue light from morning to night.
While blue light during the day plays a positive role in regulating our sleep-wake cycle, too much exposure to blue light in the evening can disrupt sleep patterns for children and adults alike. One solution is to end screen time several hours before bed. But for those who dont want to give up their nightly gaming session or Twitter scroll, blue light blocking glasses can help shield your eyes from this high-energy wavelength in the evening.

What Our Testers Say
“According to the Felix Gray website, their sleep blue light lenses are made to filter the range of blue light that impacts melatonin secretion. After wearing the glasses for a little over two weeks, I felt like I slept a little better. I also seemed to get fewer headaches after long work nights writing at my computerso for that alone, they were definitely worth it for me. One thing to keep in mind is that the glasses are on the fragile side. If you live in a home with young children or you plan to commute with the glasses, its definitely something youll want to keep in mind.” Simone Scully, Verywell writer and product tester
What Exactly Is Blue Light
Blue light is a wavelength thats naturally present in light, including light from the sun. Compared to other light types, blue light has a short wavelength. This is important because doctors associate short-wavelength light with greater risk for eye damage.
While many electronics emit blue light, computer screens and televisions typically release more blue light than other electronics. This is because computers and televisions commonly use liquid crystal displays or LCDs. These screens may look super-clear and vibrant, but they also release more blue light than their non-LCD counterparts.
Too much blue light exposure is thought to:
- affect your circadian rhythm, which can make it harder to go to sleep at night
- increase eyestrain
- cause visual fatigue
Blue light isnt all bad, though. Because this wavelength is produced by the sun, it can promote alertness, signaling that its time to get up and start your day.
And a lot of studies on blue light and eye damage have been conducted on animals or in controlled laboratory settings. This makes it hard to know exactly how blue light affects humans in real-life scenarios.
According to the American Academy of Ophthalmology, blue light from electronic devices wont lead to eye disease. They endorse using other approaches to improve your sleep, such as avoiding screens altogether in the hour or two before going to bed.

Light Exposure And Sleep Quality
Light is one of the most important external factors that helps control our sleep-wake cycle.
Before the advent of electricity, humans slept and woke according to the timing of the sunrise and sunset. Sunlight is composed of a wide range of light wavelengths, including the entire visible spectrum from red to violet as well as ultraviolet and infrared wavelengths. However, blue light in the range of 446 to 477 nm has the most significant impact on the sleep-wake cycle.
When it comes to natural light from the sun, blue light is very helpful. Exposure to a healthy amount of blue light in the daytime promotes alertness and helps you sleep better at night. However, too much blue light exposure later in the evening makes it harder to fall asleep and may also contribute to poor sleep quality and morning grogginess.
Popular electronic devices such as smartphones, tablets, gaming devices, and televisions emit blue light. Blue light blocking glasses are intended to act as a barrier between you and these artificial blue light sources to prevent your late night screen time from disturbing your sleep.

Why Our Lenses Are Better
The same way that sunglasses shield your eyes from harmful UV rays, LUMES blue light glasses can help to protect your eyes from screens.
Advanced blue light filter technology
Our top-of-the-range CR-39 lenses block up to 40% of blue light at 430nm and up to 100% at 350-400nm. The blue light blocking technology is also embedded in the lenses, instead of using a coating that deteriorates over time.
Premium Anti-glare protection
The most effective screen glasses combine blue light blocking lenses with an Anti-Reflective coating. This reduces glare from bright lights and monitors to reduce eye fatigue.
Virtually clear lens, no color distortion
Our lenses have no noticeable yellow or orange tint so you can feel comfortable wearing them anywhere. Plus they don’t affect the way you see the colors on your screen.
High-energy visible light blocked by LUMES
Studies show that high-energy light frequencies around 400-430nm are linked to digital eye strain. LUMES lenses block a significant percentage of these frequencies to reduce eye strain, headaches and other negative effects of prolonged screen use. Our lenses fully block the very highest energy light to reduce the chances of long-term conditions such as macular degeneration or cataracts.
How Does Blue Light Affect Our Sleep
There are a lot of factors in our busy lives that can affect our sleep. Obvious things like stress over a presentation or an exam, worrying about money, babies crying or cats throwing up hairballs can cause sleeplessness or interrupt a good nights rest. What we may not realize is that exposure to blue light can be a sneaky cause as well. Blue light suppresses the bodys secretion of melatonin, a hormone that regulates sleep and wakefulness. Though blue light is present in the suns rays during the day, it is less pronounced around dusk, which is why sunsets tend to appear red. The lack of blue light in the evening allows the body to produce melatonin freely, signaling that it is time to prepare for sleep. Exposure to blue light from electronic devices or artificial lighting after the sun has gone down can disrupt our circadian rhythm, making it harder to fall asleep or get a good nights rest.

Can You Test For Blue
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 couldnt find any difference between the pairs we tested and, short of a $5,000 spectrometer, theres 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 .
When youre 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.

What Is Blue Light And Do You Need To Block It
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 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, its not a good idea to banish blue light completely. Its 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 iteven everyday levels, if you spend a lot of time in front of a screenhas proven problematic. Daylight, which contains blue light, helps tell your internal clock when its 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 its 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 .

Can Blue Light Glasses Damage Your Eyes
Probably not, but that doesnt mean you should wear them all the time. The medical community doesnt believe blue-light glasses can damage your eyes but, most adults shouldnt 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 its daylight or nighttime .
Similarly, most children shouldnt 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 .

Should We Be Concerned About Blue Light Exposure
The short answer is yes. Blue light is a bit like salt, our bodies need it but our modern diet of processed food has us eating enough to make it harmful. So while exposure to blue light does have some positive benefits, our modern digital world has overexposed us to it. Blue light glasses help reduce harmful overexposure.

Do Blue Light Glasses Have To Be Yellow
In the early days of blue light glasses, the lenses were a distinct yellow, and the frames were notoriously uncool. However, these days, blue light glasses are super-stylish and designed to only filter out blue light at the higher end of the spectrum. The lenses are not noticeably yellow at all. So, while they are imperceptibly yellow , no one will ever know, unless you tell them.

Does Increased Blue Light Exposure Impact Sleep Quality
Blue light emissions from intense sunlight exposure have been linked to macular degeneration, risk of cataracts and some other eye conditions but electronics aren’t known to emit enough blue light on their own to cause eye strain or serious damage, experts at the AAO have concluded. Where blue light may be more impactful, then, is negatively influencing our circadian rhythms and late-night computer, phone and television users often experience disruption in their natural sleep cycle.
“Sleep is where blue light is likely an issue while there isn’t ophthalmic evidence, blue light likely messes with your circadian rhythm, if you’re using a lot of blue screens at night,” Dr. Eichenbaum says. “It’s good to not sit on your phone at night, or instead read a book with a yellow light or, use your blue light glasses, if you have them. That would be the appropriate time to use them.”
While blue light glasses may indeed be most effective in the evening hours, Dr. Khuruna adds that many of the best electronics today have settings to limit blue light emissions in the evening. Using these settings and new features may have the same counter effect against blue light exposure at this time of night. Blue light glasses and brightness reduction technology are just two options for working to reset your circadian rhythm and other DIY sleep enhancement tips.
