“Bandage” Solutions Won’t Protect Your Eyes!


“Adaptive brightness on cell phones, tablets, and monitors isn’t doing anything to help at all.”


You’ve likely seen a lot of our articles about how digital devices are clearly a source of many annoying issues including digital eye strain, macular degeneration, and melatonin suppression. When you ask the experts at Ophthalmic & Physiological Optics (The Journal of the College of Optometrists) and the National Academy of Sciences, they will agree you need to protect your eyes since blue light is bad for sleep! So, when you’re bathing yourself in the light from digital devices, it’ll be harder to get to sleep, stay asleep, and enjoy your sleep.

And now that there is so much scientific evidence showing how bad digital devices are for our eyes, technology engineers and developers have provided the world with “bandage” fixes: apps that manipulate screens and supposedly relieve users from being affected by artificial blue light. What could possibly be bad about that, right?

protect eyes from digital eye strain

Well, a new study has now come out with damning evidence that adaptive brightness on cell phones, tablets, and monitors isn’t doing anything to help at all. Researchers at the Lighting Research Center at Rensselaer Polytechnic Institute had already determined that blue wavelengths of light suppress the release of melatonin. Now, however, their latest research has shown that subjects who used a digital device with an app designed to manipulate blue light intensity versus those who did not, resulted in no change in melatonin suppression whatsoever. In other words, apps which turn your screen orange under the guise that it’ll protect your eyes might only work for removing blue light, but they won’t do much in helping you sleep better. One interesting note in their study that stood out to us, though, was that the one night where all participants had an influx of fresh, sleepy-time melatonin was when they all wore a pair of blue light blocking glasses. Well, what do ya know!

Time for a Digital Detox?

A few weeks ago, we introduced the concept of health is the new wealth. Well, for many in the health and wellness industry, the idea has been around for a long time but never really in the realm of protecting eyes. Over the past year, however, and through our efforts to help educate with the assistance of professionals in all kinds of related fields, things are changing very quickly.

Your daily goals being achieved, being able to go the distance in all that you do, and then getting a meaningful night’s sleep are incredibly important. Most Americans take steps each day to boost their energy and health whether it’s through exercise, an extra cup of coffee, going for a reinvigorating walk outside, or, believe it or not, by giving their eyes a break. The latest concept beginning to build up steam is for people to give themselves a digital detox. It’s not a bad idea. But for many, it’s also either not an option or a desired alternative to staying connected.

protect eyes from computer screen

Based on cited studies from Pew Research Center, Nielsen, and Oxford University, there is an ever-growing number of people all around the world who are affected by the artificial blue light emanating from their digital devices. Since statistics show more than 83% of Americans report using a digital device for more than two hours a day, 60.5% of those people in turn report experiencing digital eye strain. This was all revealed this year at CES in Las Vegas by our friends at The Vision Council. On top of that, the American Medical Association recently issued a warning to all cities in the U.S. to stop using LED lighting because of how intense the blue light can be and disruptive it is for circadian rhythms. From this, Harvard then studied the issue further showing overly-lit conditions (extensive artificial lighting) can increase the risk for cancer.

With so many new studies coming out about just how bad not protecting your eyes can be, it’s no wonder those in the health and wellness communities are now also jumping on board and encouraging everyone to take more precautions. Why wouldn’t you? It’s simple: when you’re unable to disconnect and walk away from a digital screen, and for all the times you have to keep staring at one, protecting your eyes is the best solution to avoiding harmful, high-intensity blue light. As we shared before, apps and devices that manipulate screen colors in order to lessen blue light are all well and good, but not nearly enough. And in max settings, everything being orange is definitely not ideal. So why bother struggling and avoiding the simplest, most convenient way in which you can get more protection than anything else?

glasses to protect eyes from computer screen

Of course, we’re tooting our own horn here a bit, but with good reason. No one else compares to our tech, and since our lens design is patented, you know you’re getting top-quality. As well, with our new BPF (blue-light protection factor) rating, you can clearly gauge the difference in our lens options as well as in comparison to our competitors. For more information about BPF and why a healthy start to your day begins with your eyes, click here.

If you’re sick of the tired, itchy, burned-out feelings in your eyes and want to return to getting a good, deep, solid night’s rest, head to gunnar.com and join the Movement that’s sweeping across the planet.

Health is the New Wealth

2018 is upon us and so begins a fresh start for countless people. It’s the season of New Year’s Resolutions when millions of individuals will promise themselves to eat more nutritious foods, increase their vitamin intake, hit the gym on a regular basis, and all sorts of other efforts in order to achieve a healthier and happier version of themselves. However, for most, one integral part of their body is neglected: the eyes.

eye health

Everyone’s day begins when the eyes open and ends when they close, so it makes perfect sense to protect them in between. And given the incredible amount of new information being released about the need to protect the eyes, now is the time for a digital eyewear movement like no one has ever seen before (pun intended). Just take a look at WebMD; they recently posted an article that shows wearing amber-tinted glasses is recommended to improve sleep quality. The study is based on a newly published article in the Journal of Psychiatric Research which proved “soundness of sleep” was “significantly higher” when subjects wore amber lenses before going to bed. So, you see, health really is the new wealth!

It’s no mystery that efforts by many to live a healthier life have increased. In fact, since 2013, the health and wellness industry has grown by nearly 11%, and earns around $4 trillion a year with nearly $550 billion going to mind and body fitness. From expensive, healthy customized diets to specialized personal training, millions of people are shelling out thousands of dollars each year to better themselves. Yet, the same eyes they use to spot these deals in order to improve their health is the one part of their body that’s ignored the most. Whether indoors or out, many people just don’t feel the need to put on a pair of glasses or sunglasses in order to avoid damaging waves of light. Outdoors, it’s ultraviolet light which has been proven time and again to damage corneal tissue. Indoors, it’s the dreaded artificial blue light that’s really the beast of eye damage.

protect eyes

If you’re just catching up on what’s been getting a lot of attention lately, blue light is the only wavelength that penetrates deep into the eye and can adversely affect the retina. With sunlight, the natural part of our biological clocks kicks in. Blue light triggers an enzyme in the eye which sends a message to the brain to turn off melatonin (the natural chemical that makes us sleepy) and we wake up. As the sun goes down, the results are reversed and we get tired. Since it’s the 21st Century, though, we’re now inundated by electronic devices at nearly every turn. Cell phones, laptops, tablets, dashboards, even some refrigerator doors! Digital screens are everywhere and they all emit a whole lot more blue light than the sun. Specifically, the peak of blue light from 400 to 450 nanometers is the most damaging. Beyond 450, we get a wavelength of blue light that’s actually healthy, helps your mood improve, and increases focus.

Now, if you’re one of the 83+% of Americans who use a digital device for more than two hours a day and part of the millions who experience eye strain, dry eyes, headaches, blurred vision, and even neck and shoulder pain, then say hello to digital eye strain because that’s what you have. And if you think these numbers are alarming, don’t hold your breath for a reprieve because our world is only getting more wired as you read this. Not only are our eyes exposed to harmful blue light at nearly every turn which can cause macular degeneration, cataracts, and permanent damage to the retina, that same blue light is also causing us to lose quality sleep. So, in a world concerned about health, wellness, and improving livelihood, why are so many disregarding their eyes while dumping thousands of dollars on everything else? It makes no sense.

eye health tips

What we weren’t expecting as we headed into 2017 was for a new era of urgency to be ushered in. We had professional athletic directors and teams reach out, health gurus, exercise experts, and many more come knocking on our door looking for a way to improve their sleep quality while protecting their eyes throughout their digitally-soaked day. Even fashion-conscious celebrities and organizations wanted to work with us because digital eye strain is a very real issue for all people from all walks of life. 2017 turned into a GUNNAR Movement which we’re now riding into 2018. Not only are we working hard on developing new styles and technology to go with them, we have some really ambitious partnerships to announce very soon. This has all led us to wonder how we can make it easier for you to decipher exactly what you’re getting when you invest in GUNNAR products and your health.

healthy eyes

Today, we’d like to announce a new lens protection rating system we’re calling BPF: blue protection factor. BPF is a scientifically applied protection rating designed to help people compare the efficiency of the blue light protection from their screens which they receive from their glasses. Starting now and similar to SPF (sun protection factor), all of our products and comparisons will come with a BPF rating so you can clearly see what level of protection you’re getting. The GUNNAR patented amber lens carries a BPF of 65 in comparison to most other competitors that have a BPF of 18. Wearing a lens with a BPF value of 65 means that the lens blocks a minimum of 65% of incoming blue light from 380nm to 450nm, and 100% of UV light. Since the most damaging and intense blue light is nearer to 450 nanometers, you know GUNNAR protection will be vastly superior.

Protecting your eyes is our #1 goal. Ever since GUNNAR was established over 10 years ago, we’ve remained close to optometry professions to ensure our products are of the highest quality on the market. Whether you’re a hardcore gamer, engineer, accountant, student, or just on a computer a lot, GUNNAR provides the highest protection available – protection that helps you see better, play longer, and improve your health. On top of that and with the introduction of the BPF rating system, we’re able to go one step further in making sure you know you’re getting nothing but the best with GUNNAR Optiks.

Do Apps That Block Blue Light Improve Sleep Quality?

With studies coming in left and right, it’s becoming more and more obvious that exposure to artificial light—especially from digital devices—is negatively affecting a growing number of people. Recently, NPR dove into the arena and reported on whether or not applications for phones, tablets, and computers were helping block blue light and improve sleep quality. Spoiler alert: they’re not.

blue light sleep effects

While both experts NPR interviewed said there is value in using the apps—which we agree, there is some value—you’re still not getting enough protection. On top of that, with a light-shifting program, you’re causing the colors of your screens to be manipulated and they end up looking like they’ve spent too much time in a spray-tan booth. Whether you’re into art, gaming, photography, or just surfing the web for fun videos or products, the last thing you want is for everything to look unnatural. Especially memes. Besides, even in an orangey state, screen brightness still contains blue light.

blocking blue light makes you sleep better

In steps David McLeod, an Optical Business Manager for an eyecare company in Georgia. In his interview with FOX/ABC WGXA.tv, McLeod warns that overexposure can lead to macular degeneration and retina damage. Just when you thought not getting enough sleep was bad, in steps this guy to say you’re going to go blind! Dramatics aside, he is definitely correct. While it may take a while for that kind of damage to occur (though increasingly so thanks to so many things being wired and digital these days), they are issues which can be prevented starting today. As Professor Brian Zoltowski pointed out in the NPR article, we’re surrounded by artificial light—there’s no escaping it. Taking steps to decrease exposure is all well and good, but not everyone can escape the light. So that leaves you with two choices: A) Change your life such that you can get away from artificial sources of light well before bed or; B) Put on a pair of glasses—as recommended by David McLeod—that will protect your eyes all day and night.

how to get more sleep

If you’re tired of feeling the strain, not getting enough sleep, and if you’re worried about the health of your eyes, it’s time to get a pair of GUNNAR. No need for an app—get the protection that will help restore the sleep you’ve been wanting. Check out our latest styles, Axial and Valve.

Doctor Recommended for a Reason

GUNNAR glasses have long been doctor-recommended for one important reason: they protect your eyes. So, it’s no surprise to us when well-respected medical professionals like Dr. Ryan Corte, O.D. agree. In his recent article, Dr. Corte lived up to his promise of being passionate about educating his patients and explained our technology in great detail from his perspective as an optometrist. He’s not just someone who bases his beliefs on data and science, he’s also a GUNNAR user thanks in part to the need he had in protecting his eyes after having LASIK surgery some time ago.

dry eye treatment

It’s a little shocking at this point in time, however, that there are still quite a few people who aren’t familiar with digital eye strain. As a matter of fact, in a study done earlier this year by Novartis and Johns Hopkins University, 64% of the 6,000 surveyed weren’t informed about the medical condition. This same study also revealed a very interesting fact: 81% of surveyed university students had clinical signs of dry eye (one of the symptoms of digital eye strain) but only 41% reported the condition. Chances are, most just think the effects of digital eye strain are related to something else, and not a direct result of increased and repeated exposure to artificial blue light.

computer eye strain symptoms

This is where Dr. Corte’s article comes in and at a very important time in human history. The Digital Age is very much upon us, and the number of people exposed to digital devices for much of the day is increasing at an extremely high rate. The need to protect your eyes has never been more important, especially now that a growing number of studies are coming out and reaffirming what optometrists like Dr. Corte have long known and feared: digital eye strain is a very real and very serious condition that needs to be addressed on a daily basis. From losing quality sleep to the early onset of macular degeneration and on to many other long-term conditions and eye damage, leaving your eyes to fend for themselves when bathed in artificial light that they’re not meant to be exposed to will only yield greater medical issues, pain, and loss of cognitive function.

Give Dr. Corte’s post a read when you have a few moments. If you’re ready to get on board and protect your eyes, the styles he enjoys using are Sheadog, Mod, and Intercept which are all in stock today.

Ladies, Prioritizing Your Eye Health Will Help Your Workplace Productivity!

The health and wellness gurus at Well+Good just posted an interesting article which discusses the need for women to pay better attention to their eye health, and we couldn’t agree more. Noting the 20-20-20 rule for keeping eyes fresh and rested throughout the day, W+G also shed some light on a recent release which stated women are more likely to suffer from chronic dry eye, inflammation, and vision impairment when compared to men. As you already know, these are just a few of the many symptoms of digital eye strain which is exactly what GUNNAR eyewear prevents.

So, if your “#bosslady goals” are to keep excelling and getting the job done well, follow Well+Good’s advice and then take it one step further by protecting your eyes with GUNNAR. You will immediately feel the difference and, therefore, be able to spend more time on increasing your workplace productivity.

Your Digital Screens Could Be Destroying Your Life

Let’s face it, you’re surrounded by digital screens. What was once fantasized in sci-fi films is now a reality. From laptops to tablets to cell phones, our world has gone from analogue to digital in a matter of a handful of years. And while the convenience of having so much available at your fingertips has helped society excel in many areas, it has also caused an alarming amount of people to suffer from digital eye strain. Digital eye strain is a real-life medical condition immediately associated with exposure to artificial blue light, and according to a recent study 90% of the U.S. population is at risk of suffering from it. Symptoms include eye fatigue/tired eyes, eye strain, headaches, irritated eyes, itching/burning eyes, blurry vision, and general fatigue. As well, long-term exposure to blue light has been linked to cataracts, depression, macular degeneration, and other diseases.

To help simplify things a bit, here’s a commercial we recently did that quickly explains the condition:

Bear in mind, we’re not making any of this stuff up – digital eye strain is very real. While we coined the phrase “digital eye strain” nearly 10 years ago and the medical establishment has since accepted it as official terminology, they have done their own research which has yielded some extremely eye-opening facts about artificial blue light, how it can hurt your eyes, lead to diseases, and negatively affect your sleep. Examples of their independent studies can be read here, here, here, here, and here.

Now, the official explanation of what digital eye strain is comes from our friends at the American Optometric Association:

Computer Vision Syndrome, also referred to as Digital Eye Strain, describes a group of eye and vision-related problems that result from prolonged computer, tablet, e-reader and cell phone use. Many individuals experience eye discomfort and vision problems when viewing digital screens for extended periods. The level of discomfort appears to increase with the amount of digital screen use. Symptoms associated with Computer Vision Syndrome (CVS) or Digital Eye Strain are eyestrain, headaches, blurred vision, dry eyes, and neck and shoulder pain.

Viewing a computer or digital screen often makes the eyes work harder. As a result, the unique characteristics and high visual demands of computer and digital screen device viewing make many individuals susceptible to the development of vision-related symptoms. Uncorrected vision problems can increase the severity of Computer Vision Syndrome or Digital Eye Strain symptoms. (RE: AOA.org)

reduce eye strain

Something else to note that is at the very root of digital eye strain is the high frequency of artificial blue light bombarding your eyes. It is a lot more intense than the level you receive from the sun, and it’s also the only color wavelength that penetrates your cornea and directly hits your retina. Bad blue light ranges from 380 to 470 nanometers, but there is also good blue light which ranges from 470 to 500 nanometers. The reason it’s good is because at these frequencies, it triggers enzymes and chemicals in your brain that help promote memory and cognitive function. They also stimulate the photosensitive retinal ganglion cells that, in turn, stimulate pupillary reflexes and control the circadian cycle. This is getting pretty science-y so if you’re truly curious, you can read what the experts at All About Vision have to say about blue light in their independent analysis here. There’s also a website dedicated to explaining how blue light can be bad for you which you can find here.

eye strain pain

What shouldn’t be flippantly disregarded, though, are the issues you could potentially suffer when exposed to blue light. These include melatonin levels being diminished leading to a disrupted sleep pattern (circadian rhythm), retinal damage, macular degeneration, cataracts, depression, and eye disease. Some studies have even shown that blue light can trigger chemical reactions in the brain that can lead to diabetes, weight gain, and even cancer. Given that the gateway for living life begins with your eyes, protecting them has never been more important.

As a result of the advancement of our technologically-inclined society and the saturation of digital devices in our lives, more and more people are feeling the negative effects. The Vision Council, the leading organization for championing better vision for better lives, does an annual study on digital eye strain and this year’s numbers are frightening. According to their research more than 83% of Americans use a digital device for more than two hours a day, and of those individuals, over 60% experience symptoms of digital eye strain.

In an effort to help combat the growing number of issues many digital device users experience, there has been a major push to incorporate digital solutions into technology – specifically, applications or settings which help diminish the level of artificial blue light being emitted. Some of these apps are free to use/install, while other advancements are programmed right into device settings and expensive monitors. The end result, however, is a screen that’s distinctively orangish in hue, as if it had one too many spray-tan sessions.

how to relieve eye strain

Granted, these advancements in tech are a great step forward in helping to combat the growing problems associated with digital eye strain and blue light, but they’re simply not enough. Digital eye strain, as was quoted above, is “a group of eye and vision-related problems”, not just a result of artificial blue light. First, your eyes are a muscle and work their hardest when looking close up at a digital device all day. It’s like running a marathon and then trying to walk home afterwards. Your leg muscles would be too fatigued to carry you let alone stop from shaking. This same principle applies to your eye muscles as well. Second, the harder you gaze at a screen, the less likely you are to blink which, in turn, dries out your eyes. It’s a medical fact that blink-rates drop significantly during intense viewing which increases irritation. Third, glare from digital screens and the fact that they flicker as you try to concentrate on tiny letters or details cause your eyes to quickly become fatigued and irritated which can even lead to headaches.

Where applications and settings let you down is in these areas. Tuning out the blue light being emitted might help a little, but it won’t stop all of the other symptoms associated with digital eye strain. These apps and expensive color-shifting monitors still shower your eyes with high levels of artificial light. Masking the color focus or shifting the light spectrum does not change the fact that devices with a screen are illuminated by spikes of artificial light including blue light. Although these solutions may shift the amount of HEV blue light produced naturally by the devices, they do not reduce it enough. Besides, if you’re looking at a color-rich image or game, you can’t honestly say you’d prefer to see it bathed in orange, right? This now leads to another problem: few people actually take full advantage of a blue-blocking app or setting. Most likely, this is due to the significant manipulation of colors in how they’re seen on screen, and so blue light is still getting through and directly hitting the retina.

what does eye strain feel like

When you weigh all of your options, and despite some of these applications and settings being free, you’re missing out on so much more and still hurting yourself in the long run. Realistically, these solutions only address one of the causes of digital eye strain. The big difference is that GUNNAR addresses all causes of digital eye strain. GUNNAR amber lenses block the most HEV blue light at 65% providing you with a natural viewing situation and the most protection, they add contrast to help sharpen text and images on your screens, added focusing power pre-focuses the light and reduces stress on the eyes muscles caused from close distance viewing, and our patented lens designs help hold in humidity while blocking air currents to prevent dry eyes. So, you can keep using these apps and settings if you so choose, but for full protection, you’ll want to put on a pair of GUNNAR glasses.

Get on the GUNNAR bandwagon and never again worry about having to suffer from digital eye strain. We’ll take care of your eyes so you can be a better you all day, every day.

Nobel Prize Awarded to Circadian Rhythm Doctors on How Artificial Light Affects Your Sleep

Congratulations to doctors Jeffrey Hall, Michael Rosbash, and Michael Young for winning the Nobel Prize in Physiology or Medicine! These three American medical professionals studied fruit flies for decades in order to isolate one specific gene that dictates the body’s circadian rhythm. What’s crucial about their life’s work is how it’s led the way for a much more robust understanding of how artificial light can affect our well-being and sleep. Another important thing to note is their work was chosen to be awarded over ground-breaking discoveries in gene-editing as well as immuno-oncology which is the process of fighting cancer by jump-starting the immune system.

The TL;DR version of their work is this: we all have a constellation of proteins in our DNA which work together in order to keep us functioning on a 24-hour cycle. This process includes when and how well we sleep. In this cluster is one particular protein which allows light to have an influence on our body’s clock. Letting in more artificial light will disrupt the cycle and thus cause our brains to not want to sleep (melatonin disruption). What happens when you don’t get enough sleep? As we previously posted, you risk impairing your memory, increasing your chances for injury and disease, perpetuating the issue through neurotoxin buildup which further disrupts sleep, and becoming more prone to depression.

In the end, their incredible efforts have led to major advancements in sleep science. This really is an amazing achievement and worth the 5 minutes to read the whole story on Wired.com which you can find by clicking here.

With GUNNAR Optiks and our technologically enhanced eyewear, you can help preserve your body clock and get the proper sleep you deserve.

The Mission: Protecting Your Eyes

When it comes to summarizing why GUNNAR Optiks exists, leave it to the brainy and eloquent literary geniuses at The Mission to hit a home run. In their latest article, they feature a treasure-trove of really meaningful information about digital eye strain and how GUNNAR can help prevent the symptoms. The Mission’s easy-to-read story weaves readers through the facts, information about blue light, what is digital eye strain, and then it closes out with some very helpful solutions. Why so serious? Because it is very important to protect your eyes as they are an integral part of the body that regulate sleep patterns, hormone production, and the body’s timeclock. And, bonus, there’s a very savvy video near the end that covers it all. You can read the article here, and we’d love it if you would help spread the word.

Our mission with the help of The Mission is to protect your eyes. No time like the present to join the Movement of believers who want to end the pain of digital eye strain.

Steps You Can Take to Combat Computer Vision Syndrome

We’ve long been touting the necessity of protecting your eyes because it’s why our company exists in the first place. Well, now the prestigious and well-respected Reader’s Digest has joined the fight. They recently jumped on board and shared some ways in which you can keep your eye balls safe. As Reader’s Digest noted, “When you stare at computers (or devices like smartphones and tablets) for too long, the muscles in your eyes have to work overtime. And ‘like any muscle, if you’re constantly using it, it can break down,’” says James Stringham, PhD, research professor at the University of Georgia. Given the amount of time we’re all spending staring at a digital device, it makes sense that one of the biggest publications of all time would want to help spread the recommendation.

computer vision syndrome symptoms

Steps you can take include eating leafy greens, corn, and orange peppers, practicing the 20-20-20 rule (every 20 minutes, look at something 20+ feet away for 20 seconds), taking supplements if leafy greens aren’t your thing, limiting your exposure to artificial blue light, and, surprisingly enough, wearing reading and blue-blocking glasses. Wouldn’t you know it, we have those!

Revolutionary Eyewear for All

Sheila Gaspers from TangoDiva.com recently picked up a pair of the GUNNAR Haus to help combat the digital eye strain she was feeling on a daily basis. And after a few weeks of testing, she found that she not only felt much better, but she also turned a few heads at the office thanks to the Haus’ “haute” styling. Her review, which was recently posted, isn’t too long but it’s certainly positive, and we genuinely appreciate her taking the time to highlight our eyewear on their website.

We receive quite a few reviews throughout the year, but what makes this one especially unique and important is that it appeals to a mostly female audience. GUNNAR Optiks wasn’t founded to just benefit gamers and males, but to help all computer users protect their eyes from computer vision syndrome. We feel features like this are worth highlighting because we’re passionate about everyone understanding the benefits of our computer glasses. Thank you, Sheila and Tango Diva!

Haus comes in three colors, Onyx, Onyx Fade, and Tortoise, in both amber and crystalline, and they’re all currently in stock.

Are your computers destroying your body?

By Frank Gimbel, ABOC-AC

Screens are just about everywhere we look today. Whether they are in the form of flat-screen TVs, PCs, laptops, cell phones, media players, smart watches, or some other technology, all of these devices can emit harmful blue light that can create digital eyestrain. With all this technology surrounding us, questions are stirred about the harm they can cause to the eye and overall health in general.

The dawn of the personal computer age has opened the door to what is known as CVS (Computer Vision Syndrome), or commonly known as digital eyestrain. This condition plagues all ages, spans all occupations, and can harm anyone who uses a computer or display device for prolonged periods of time. Let’s face it, our eyes were not designed to focus upon a specific finite distance for countless hours without experiencing fatigue, eyestrain, dry eyes, and blurred vision. Other disturbing factors can be noted with neck and back pain, double vision, vertigo, and polyopia (the struggle of refocusing the eyes). Additional aggravators can include poor lighting, improper ventilation, and screen glare. With extended computer use and other display devices, we are forcing our eyes to stay fixed on a specific distance for a prolonged period of time. Theoretically, this is highly unnatural for our eyes, and CVS affects about 90% of the people who invest three or more hours per day on a computer according to the National Institute of Occupational Safety and Health.

1e_webWe are now living in a wired world, dependent on digital devices, and susceptible to CVS more than ever. This widespread condition affects 70% of Americans and is growing daily. While CVS is most prevalent due to the action of eye movements and focusing, a New York Times study of pre-university students acknowledged that a large number of affected users do not have proper ergonomic computer set-ups in their work environment. The position of the user—seating, lighting, distances, screen size, foot placement, wrist and hand movements—all play a critical role in how one should set up a workstation in order to maximize comfort, efficiency, and ward off Computer Vision Syndrome.

When it comes to the conversation about digital devices, the discussion inevitably turns to blue light. There are two different types of blue light to consider. The first type is the healthy kind that helps to regulate our circadian sleep rhythm. It boosts alertness, heightens reaction times, elevates moods, and increases the feeling of well-being. This is the healthy type, and it’s what we all need to help lead a balanced and healthy life.

1dBlue light is a natural trigger and our bodies respond to its presence by suppressing melatonin production in the brain. In fact, all light tends to suppress melatonin production, but blue light “does so more powerfully” according to a May, 2012, Harvard Health Publications report. Melatonin is a hormone produced by the pineal gland that influences our circadian rhythms: our body’s natural 24-hour cycle controlling the physical, mental, and behavioral changes that we experience on a daily basis. These circadian rhythms tell us when to be awake and alert, and when to rest. We’re just beginning to understand the powerful effects that inappropriate or untimely lighting may have on our well-being, but already the facts are starting to pile up and high-energy (blue) light is the subject of much of this focus.

 

1cSleep disruption is a significant issue for millions of Americans, both adults and children. More than 40 million suffer chronic sleep disorders, and 20 million more report occasional problems sleeping according to the Anxiety and Depression Association of America. Poor sleep habits promote irritability, and can significantly affect all areas of our physical health including reduced work performance, mood disorders, high blood pressure, risk of stroke, and diabetes. Studies show that exposure to blue light a couple of hours before bedtime can delay deep REM sleep significantly. The prevalence of blue light in our sleeping environments has many physicians worried.

The second type is harmful, and has been suggested to be a leading cause of macular degeneration and other hazardous ocular disorders. In terms of the visible light spectrum (ROY-G-BIV), blue light occurs between 380 nm to 500 nm. A nanometer (nm) is measured as one billionth of a meter (0.000 000 001 m), and is commonly used to measure a wavelength of light. What we are talking about when we discuss blue light is particularly High Energy Visible (HEV) light, the violet/blue band of the color spectrum which exists everywhere around us, whether we are indoors or outside. Blue light is actually everywhere. When outside, light from the sun travels through the atmosphere. Inside, blue light can be found in fluorescent lights, LED bulbs, and through the emission of electronic devices such as cell phones, tablets, and laptop computers.

Prior to 2010, the conversation about blue light was most often connected to outdoor exposure and discussions about UV protection. This was the case until April 2010 when the release of the first iPad spawned what was to become “The Tablet Revolution”. Before long, these new-age devices were mass-produced by many competitors in the market, and more tablets flooded shelves in stores and were openly embraced. Tablets soon became the go-to media platform replacing many magazines, newspapers, and paperback books. While these new high-tech devices reduced paper waste, they quickly outsold traditional computers, and created new types of visual problems to combat. When using standard computers on desks and tables, the screen is positioned at a safe mid-distance range. Tablets, on the other hand, are held at 12-to-24 inches from the eyes, and their portable nature increases average hourly usage. Interconnectivity with smartphones and apps became prevalent, and now over 35% of Americans own at least one tablet.

The downside to using tablets, smartphones, and other devices is the backlit display. Displays typically work through LED (light emitting diode) technology, and vary between white LED and RGB backlit designs. The white version is most often used inside mobile LCD (liquid crystal display), desktop, and notebook screens. White LEDs are normally made from a blue LED with a wide spectrum of yellow phosphor to create the emission of white light. The second type of backlit display most often found is made from an RGB LED design where red, green, and blue LEDs are controlled to produce different color temperatures of white light. Concern about blue light exposure relates to its placement on the color spectrum. Compared to longer wavelength colors within the spectrum, blue light and HEV wavelengths are shorter and glimmer easiest on backlit displays. This flicker effect causes glare, and can lower visual contrast inherently decreasing clarity and sharpness on backlit devices.

1aThe naked eye alone does not have enough protection to filter out the harmful types of blue light. Extended exposure to it can lead to retina damage and loss of vision, and it can contribute to age related macular degeneration. With 93% of teens owning or having access to a computer, it has become imperative to begin educating them about the risks of blue light, the different types, and why it’s important to protect their eyes now while using these devices.

Typical viewing distances for digital devices vary. Desktop computer screens are usually set for an approximate 22-inch focal length from the eye. This standard focal distance of about 22 inches was common with most computer use, and generally speaking, worked well for many PC users. Then, as technology changed, this standard became about 18 inches with the adaptation of more laptops. Now, with even more tablet use, we find focal lengths to have moved even closer since these devices are positioned 12-to-24 inches away. Smaller gadgets such as smart phones are even closer when used for text messaging, for example, placing even more strain on our eyes causing headaches and visual fatigue. As the day winds down, device users tend to move their backlit devices closer for visual comfort. The reason behind this is that the focusing system of their eyes begins to “lock up”, and they then move objects closer to keep the muscles of the eyes in focus. By doing so, the end result is that they only induce more stress on the eye creating greater strain and discomfort. All of this exposure to technology creates an immediate need for products that help defend our eyes from digital devices and enhance proper vision.

According to The Vision Council DigitEYEzED Report, approximately 70% of American adults experience some form of digital eyestrain due to lengthy use of electronic devices. The most common report for computer usage per day varied from 6 to 9 hours, and the number of adults now spending more than 10 hours per day rose another 4%. When it comes to computer or tablet use, the eye is simply not designed to focus on pixels and hard targets. The most likely time adults experience digital eyestrain is between 6:00pm and 9:00pm, and 63% of adults did not know that their electronics emitted high-energy visible or blue light. This was one of many staggering headlines to discover, and the figures are only expected to grow with more digital dependency and use.

Ways to prevent digital eyestrain can be tied to proper ergonomics. When it comes to using a computer, it is ideal to have overhead lighting but not brighter than the monitor. This should be the brightest light in the room, and the top of the monitor should be at eye level or just below. Proper viewing distance is key and should vary between 20 and 40 inches—one arm length from the screen. Keyboards should be placed in an area where the wrist is comfortable, and the upper arms should hang vertically with the torso. Supportive chairs that allow the user to firmly position their feet flat on the floor are needed as well. Lastly are eyeglasses that block high-energy visible blue light.

Extended computer viewing has many drawbacks to note. One is reduced blink rate. Studies have shown that a computer user’s blink rate over an extended period of time can reduce to as much as one-half to two-thirds of the normal rate at which one would blink if not working on a computer. This translates to drier and more tired eyes.

1f_webTo help combat this and enhance vision, GUNNAR Optiks offers a wide array of specialized blue light prevention gear to help protect your eyes from this entire screen-based technology. The lenses trick the eyes to think they are focusing far away, allowing the eyes to relax and feel like they are focusing at distance. Available in over-the-counter and prescription options, their lenses are designed to reduce eyestrain, headaches, blurred vision, and even dry eye syndrome. One key point to note is that all over-the-counter GUNNAR lenses have a slight focusing power in their design. The power is a +0.20D add that aids with close visual needs providing extra clarity and promoting less strain.

GUNNAR’s computer glasses use proprietary wrapped lens and frame shapes to help prevent dry eye syndrome, and keep the eyes lubricated and refreshed. Their frame designs limit air currents from drying the eye, keep in healthy humidity, and allow for more visual comfort. GUNNAR views the number one alleviated symptom of computer vision syndrome is dry eye syndrome. This leads to a greater reduction of corneal abrasions, corneal scaring, and encourages protective tear film layers to remain replenished while working away at the screen.

Let’s not forget about another booming segment to consider: gamers. According to Polygon.com, more than 155 million Americans routinely play video games. Over 42% play for at least three hours per week, and at least 4-out-of-5 American homes contain some type of gaming console used to play video games. These numbers are staggering, and prove to highlight the popularity of what Americans like to do for hobbies and leisure time. Thinking in terms of lenses, all gamers can benefit from some type of blue light protective and screen-enhancing eyewear. For a more in-depth rationale on the topic, gaming is much more than just a hobby—it’s a culture. Even considering statistics from 2014, U.S. gaming consumers spent $22.41 billion on games alone. The average player is 35 years old, and the generic stereotype ends there. Gaming reaches all ages: 56% are male (and yes, the remaining 44% are female), 26% of players are under 18 years of age, and 27% of video gamers are over the age of 50.

Over time, much like the TV and cable industries, games have become digital. They are purchased frequently online rather than in a physical store, and are played on more computer devices than ever before. Committed players acknowledge that they spend at least 6 and a half hours per week playing online games with others over the internet, and another 5 hours per week playing with other players in person. Of these frequent players, 15% spend even more time playing with their partner or spouse at home. As eyecare professionals, we have a lot to consider about our patients who enjoy spending this much time intently watching screens.

1g_webIn addition, this digital shift appears to only be increasing, and console games and systems are quickly being left behind for more PC and tablet based gaming options. In 2010, the digital video game market only took a 29% share of the total gaming market. Four years later, digital sales almost doubled accounting for 52%, while physically purchased games were finally trumped and only made up 48% of the video game market.

The muscles of the eye function like the shutter and zoom of a camera. They bend and flex to allow for the items viewed to be seen as clearly as possible. Think of the muscles as if they were rubber bands. Throughout long periods of uninterrupted near-distance flexion of these eye muscles, the eye can lose elasticity and experience blurred vision, difficulty focusing, double vision, and eyestrain. GUNNAR has devoted itself to working on this extensively. Its lens design pre-focuses the light coming off of a screen to encourage the muscles of the eye to relax. In addition, the lenses enhance colors and allow details to appear sharper while looking at the screen. When setting out to find a lens material that was as tough as polycarbonate yet provides the optical clarity of glass, GUNNAR could not find one to meet its needs and created its own proprietary material. The end result is a plano mid-index of 1.51, with a low-density, high-ABBE value, and high-light transmission lens that provides minimal haze and delivers ultra-sharp optics. The lens appears to be crystal clear, and GUNNAR prides itself on its high degree of color control. Its goal is to create lenses that are enhanced to work with engineered tints and band-pass filters properly, all without any edge defects. GUNNAR claims its lens materials offer an optically-pure viewing experience with ultra-light, ergonomic properties for all screen users.

These lens ingredients make GUNNAR an ideal candidate for dedicated computer users, tablet aficionados, smartphone fanatics, and gaming enthusiasts. The lens purposely blocks out 65% of artificial HEV blue light. This percentage mimics the equivalent amount of natural blue light needed to help aid in overall health for the body and brain. The nanometer band focuses the coverage across the 400-to-450nm spectrum values which is also the most damaging to the eye. While GUNNAR primarily focuses its lens specialty on computer use, its wide range of tint enhancements allows for tailor made usage environments matched to recommended lens tints. Traditionally, the lens tint is the amber hue designed precisely for the type of light emitted from a computer screen. This tint allows the wearer to see in optimized optics, and feel the sensation of viewing the image in an eye-preferred natural light environment. The amber lens tint filters more fluorescent light and reduces high-intensity blue light, also filtering out 65% of HEV blue light at the 450nm light spectrum. While this lens tint can be worn by all, GUNNAR also produces its crystalline lens tint which is designed for graphic artists, photographers, video editors, and those who need to see in true color. This tint provides all the same benefits as the amber lenses, except it will not filter, contrast, or shift the color spectrum while worn, and it will filter out 15% of blue light at the 450nm light spectrum. The third option from GUNNAR is the non-polarized outdoor tint. It has been designed to provide a relaxed and dramatic visual experience for those who enjoy using their digital devices outdoors.

1bScreens emit glare and reflections, and any high quality optical device must have a cutting edge anti-reflective coating to reduce glare, and allow for more light to transmit through the lens to reach the eye. GUNNAR lens coatings all uphold high levels of scratch resistance while maintaining hydrophobic and oleophobic properties to reduce grease, moisture, and haze from their lenses. Prescription options are also available. Each single vision lens, regardless of power, comes with all of the coating and tint options specified above. In prescription form, GUNNAR’s material of choice is polycarbonate. However, upon special request, a 1.67 high index can also be obtained. All prescription lenses have the option to be ordered with either a crystalline or amber tinted lenses, and come with a blue flash anti-reflective coating on both sides.

Blocking Blue Light May Help Treat Bipolar Disorder

According to a new article published by Newsweek, a recent small study of 23 bipolar disorder patients by Dr. Tone Henriksen from the University of Bergen and Valen Hospital in Norway yielded some major results. During a one-week period, 12 individuals were given eyewear designed to block blue light while the other 11 were not. No other changes were made to their lifestyles or medication. The Young Mania Rating Scale, which is designed to measure manic behavior, was then applied to the patients and those who wore the amber-tinted eyewear scored an average of 14 points lower than the others.

To better explain the significance of this study, those 14 points were more than double what doctors consider to be a “clinically significant difference”. As one researcher and psychiatrist put it, these were “knock-your-socks off results!” The important thing to point out is research into the effects of light—specifically blue light—has increased and continues to show how important it is to protect yourself. We take great strides to help protect you from the effects of digital eye strain, and we’re extremely honored by the thought that our eyewear could potentially benefit people who suffer from bipolar disorder.

Protecting Your Eyes in More Than One Way

Not long ago, we shared some pretty interesting statistics and information about Computer Vision Syndrome (digital eye strain), and how it’s a global condition. Since then, there have been some people who have asked us to better explain what we do. While the information has been readily available on our website, perhaps it’s time to simplify it a bit.

First, let’s make sure you fully understand Computer Vision Syndrome. Lifehacker recently posted a report directly related to a new infographic published by WhatisDryEye.com which revealed upwards of 25 million Americans suffer from symptoms of dry eye. We bring this up because CVS isn’t just about blue light and damaged retinas, but more on this a bit later. Let’s get back to the basics.

What you see above are two graphs showing visible light spectrums. On the left, you have the wavelengths you receive from the sun. On the right, you have the wavelengths you receive from an artificial source, and that massive spike of blue light at 450 nanometers is the one that has medical experts and researchers very, very concerned. Why? Because blue light is the only wavelength that penetrates your cornea and directly hits your retina. As we’ve pointed out before (such as here, here, and here), this can lead to a lot of negative effects and can damage your eyes—in extreme cases, permanently.

You’re heard us throw around the whole “patented lens technology” thing before, and the graphs you see above are why we say that. Notice something similar about the red line in the left graph when compared to the natural light graph further up? Yup, that’s right! It follows the same line as the natural light spectrum almost exactly. In the graph on the right, we tried to overlay both of the top graphs together so you can see what we mean. Now, we could easily block more blue light, but we purposefully block 65% of artificial blue light because that’s about the same level of blue light you receive from natural light which is good for your body and brain. Not only that, but we provide this coverage across the 400-450 nanometer spectrum because that’s the most damaging. Pretty cool, right?

These final two graphs tell the moral of the story (which is something else we repeatedly say): GUNNAR is the only patented computer eyewear recommended by doctors to protect and enhance your vision. And now you know—actually, now you can see why.

Computer Vision Syndrome: A Global Condition

It’s no mystery that digital eyestrain—also known as computer vision syndrome (CVS)—is a real condition that many of us experience. In the past year alone, dozens of new reports and studies have shown that prolonged exposure to blue light, and increased use of digital devices, have led to a proliferating amount of individuals seeking medical help for complications. Age and occupation are completely meaningless, too; we are a wired generation and as we spend more time staring at multiple screens throughout the day, we are all susceptible to the symptoms.

CVS Global body

The growing amount of concern is so great, even the New York Times has jumped onto the CVS bandwagon. Citing recent studies done in both Africa and Iran, the NYT shared some pretty startling figures. First, upwards of 70 million workers around the world are at risk for CVS. Second, and if a study of pre-university students is any indication, most of us do not have a proper set up for using a computer that would be considered ergonomically correct.

There is quite a lot more information in the Times post so be sure to click the link above and check it out. The bottom line? It all starts with your eyes. You can’t be on a digital device for hours on end without them. And with a pair of GUNNARS in between you and the many sources of artificial blue light bombarding your retinas, you’re taking the best, doctor-recommended first step towards relief from CVS. Protect your eyes! End the pain of eyestrain by grabbing a pair of GUNNARS today.

Digital Eyestrain on the Rise

A growing number of optometrists and other medical experts have begun to get very serious about digital eyestrain. Helping give the subject recent headway in the eye care spectrum was a new study released by Vision Service Plan (VSP being the moniker most are familiar with). In it, research shows that by the time an average American teenager hits 17 years of age, he or she has spent 1/3 of his or her life staring at a digital device. That’s almost 6 years, according to VSP, or more dramatically put, 50,000 hours. And because of this amount, eye care specialists are witnessing a growing number of patients suffering from digital eyestrain.

This same study also shows that parents of teenagers are still mostly unaware of the adverse effects of artificial blue light—the biggest reason symptoms of digital eyestrain are on the rise. All of these startling figures lead to a 50% increase in exposure for Americans in general, and a 38% increase in the negative effects of blue light in kids.

Click the image above to see the full infographic from VSP.

Though public awareness is slowly on the rise, there are still issues that need to be addressed. Namely, most folks are confused or completely in the dark (pun mostly unintended) about how bad artificial blue light is for their eyes. Simply put: it’s the only wavelength of the color spectrum that penetrates directly through the eye onto the retina and can lead to a myriad of medical ailments. The other issue is the large number of individuals who suffer from digital eyestrain and don’t even know it. They rub their eyes and feel tired staring at their screens, but they just attribute it to general fatigue or a bad night’s sleep. We see a remarkable number of people who eventually find themselves in a pair of GUNNARS and realize just how bad it’s been for so long.

The bottom line? There needs to be a greater effort made in spreading the news. This goes for GUNNAR Optiks as well, hence this and previously posted blogs. The more people understand artificial blue light and digital eyestrain, the greater the chances these rising figures VSP has shared will begin to decline. Don’t forget, GUNNAR Optiks was founded nearly 10 years ago with eye protection as our main goal for existence. Even well before the medical establishment started recognizing the issues, we were right there knowing something was wrong, and that we wanted to help.

#CES2016: New Digital Eye Strain Report

The International Consumer Electronics Show is the largest technology exposition in the world. All of the latest and greatest advancements in the digital world are revealed at the event which takes place in Las Vegas. Despite there being some thrilling new inventions and breakthroughs this year, one subject took center stage: digital eye strain. During CES this week, The Vision Council released their 2016 Digital Eye Strain Report which was quickly picked up and reported on by numerous media outlets. From their survey of 10,000 adults, The Vision Council found that 70% of Americans suffer from some form of digital eye strain, while nine out of 10 of those people use electronic devices for two or more hours a day. They also reported that 27% of Americans do not know computer eyewear can protect against digital eye strain.

In an interview with CBS News, one technology sales expert who spends a lot of time in front of his laptop confessed that he experienced many symptoms of digital eye strain. These symptoms include headaches, eye strain, blurred vision, dry eyes, and more. It wasn’t until he purchased prescription glasses designed to help alleviate the negative effects of blue light and digital eye strain that he was finally able to experience relief.

Yes, there are prescription options out there to help you avoid digital eye strain, but they don’t include GUNNAR Optiks’ patented lens technology. With our eyewear, you not only find relief from digital eye strain, but you’re also protected against the negative effects of blue light while the shape of our glasses help keep your eyes from drying out. The bottom line: we’re here to help protect your eyes so you can better focus on what needs to get done whether you wear prescription glasses or not.

Here are just a few of the many media articles that were posted this week based on The Vision Council’s 2016 report released at CES:

Digital Eye Strain Debate Heats Up

The amount of research into the negative effects of high energy visible light (HEV) and blue light on our eyes has significantly increased in recent months. While vision experts agree that the sun emits blue light just like every electronic device with a screen, there is still much debate as to whether or not exposure from any specific source can be blamed more than others for causing digital eye strain. Stuff.co.nz recently asked the question, “Are screens ruining our eyes?” In their article, it’s reported that the number of hours most humans spend in front of an electronic device averages between 7.4 to 9 hours a day. And every single device is a source of artificial blue light. Even more concerning, according to Stuff, is the average number of adults who experience computer vision syndrome: 63%!

While medical experts continue to investigate HEV, blue light, and digital eye strain and their connection to macular degeneration, it’s important to remember the basics. Your eyes are a muscle and extremely intricate in design. Whether you’re working with heavy equipment, swimming, going for a hike, or on your computer pouring over your taxes, you need to keep those eyes protected. Knowing that blue light emitted by any source will affect your circadian rhythm and can be damaging to your retina, there’s never been a more important time than now to protect your eyes.

Google Reduces Blue Light

Google recently released a new patch for its iOS and Android Play Books app which added a new feature called Night Light. Featured on Engadget.com, it was reported that research done by the tech giant showed most users of the popular e-reader typically spent their time reading between the hours of 8 p.m. and 10 p.m. With the latest update, they now have the option to turn Night Light on which will slowly adjust the display to become warmer. It doesn’t completely remove blue light, but it’s a great step in the right direction.

Google-Reduces-Blue-Light-image

Since all electronic devices emit blue light which has been shown to disrupt your circadian rhythm, cause eye strain, and potentially lead to other health-related complications, GUNNAR Optiks is excited about Google’s new option. We have long supported anyone’s efforts to help save your eyes and while nothing is 100% fool-proof, coupled with a pair of GUNNAR glasses, you’re sure to truly feel the difference. Plus, you’ll be able to work harder, game longer, and sleep better!

 

Digital Device Use on the Rise

A recent publication by The Vision Council has found that the number of digital device users has increased from 45% of American adults in 2012, to nearly 70% in 2015. The appeal of having nearly everything at your fingertips has helped advance the digital age at an almost alarming rate. We say almost because for the most part, folks who use digital devices are either getting work done, being entertained, or any other benign reason you can think of. Adversely, it is potentially alarming because this means more folks are potentially experiencing digital eye strain.
