Where Can I Buy Blue Light Blocking Glasses


Recently, minimizing your blue light exposure has been the subject of many health discussions, but what even is Blue Light in the first place? Blue Light is classified on the light spectrum as HEV, or High Energy Visible light.




where can i buy blue light blocking glasses



Screen time has gone up during the pandemic. Many of us, of course, are working from home. Kids are schooling at home, clicking on computers rather than raising their hands in classrooms. And this has resulted in what's known as digital eye strain, tired and dry eyes from so much screen time. So some have turned to blue light-blocking glasses. Sales have more than doubled during the pandemic, but are they worth the cost? Dr. Mark Rosenfield is a professor at the College of Optometry at State University of New York. He conducted two studies on the effectiveness of blue light-blocking glasses on digital eye strain, and he joins us now. Welcome to the program.


ROSENFIELD: Both of the studies actually found that the blue-blocking filters have no effect, no significant effect on digital eye strain. This didn't really come as a major surprise to us because there really is no mechanism whereby the blue light should be causing digital eye strain.


ROSENFIELD: Well, we did two studies. The first study, we used the filter that blocked almost 100% of the blue light. And we had the subjects read from a tablet computer for about 30 minutes. And we found no significant difference in symptoms, whether they were using the blue-blocking filter or they were just using a tinted lens, in effect. Now, because that filter blocked almost 100% of the blue light, and very few commercially available lenses actually do that, we redid the study. But this time, we used commercially available spectacle lenses that typically only block around 20 to 25% of the blue.


And the second study was done on a double-blind basis, which meant that the subjects didn't know whether they were looking through the blue-blocking filters or just a clear lens. And the experimenter also didn't know which lens that the subjects were looking through. And again, we found exactly the same effect - that the blue-blocking filters produced no significant change in symptoms of digital eye strain.


ROSENFIELD: The only thing they may be good for is that studies have shown the blue light can interfere with our bodies' light cycle. So we all have natural rhythm so that we know when we get tired, when it's time to go to bed. If you want to look at your screen late at night, which probably isn't a good idea - but unfortunately many of us still do, then the blue-blocking filters might be useful in that regard.


All of that screen time seems to come with various ill effects on our bodies and minds, such as eye strain, headaches and insomnia. To combat those problems, you can pick up a pair of computer glasses -- also called blue-light blocking glasses -- which promise everything from eliminating eye strain to helping you sleep better.


By staring at screens all day, we're also exposed to blue light waves, which are said to cause a myriad of issues. There is conflicting evidence about how blue light exposure affects your eyes, but doctors and researches are in agreement that it does affect your circadian rhythm. More on that below.


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.


Talking to CNET, Dr. Raj Maturi, a clinical spokesperson for the American Academy of Ophthalmology, explained, "During the day, you get 10 times as much blue light from the sun as you do from your computer screen. Our bodies have evolved to deal with this light."


However, research compiled by the AOA indicates that prolonged exposure to blue light (such as sitting in front of a computer all day) might cause damage to your retina -- the innermost layer of your eye that sends signals to your brain to process what you are seeing.


Blue-light blocking glasses have filters in their lenses that block or absorb blue light, and in some cases UV light, from getting through. That means if you use these glasses when looking at a screen, especially after dark, they can help reduce exposure to blue light waves that can keep you awake.


As for me, I'm writing this article wearing a pair of blue-light blocking glasses that I've used off and on for the last few months. While I'm not 100 percent certain that they are helping my eyes, I do notice my eyes feel less tired at the end of the day.


Blue light blocking glasses have specially crafted lenses that are said to block or filter out the blue light given off from digital screens. The lenses are often marketed with lofty claims that they protect your eyes from eye strain and can help reduce potential damage to your retina from prolonged exposure to blue light.


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.


The FL-41 tint, which ranges from a pinkish color to an amber-like color, filters out wavelengths of blue and green. Those colors are bothersome to patients with light sensitivity. A study cited photophobia, the medical term for light sensitivity, as the most bothersome symptom for those with migraines.


So should you invest in a pair of blue light glasses? When it comes to preventing eyestrain, your best bet is to save your money and practice good screen habits throughout the day instead. However, if you use screens late at night and have trouble falling asleep, they may be a good option.


Swannies [blue light glasses] scored consistently well in all aspects that we tested. They have managed to combine effectiveness at filtering sleep-disturbing blue light while also allowing in non-sleep disrupting light, striking the right balance of sleep benefits.


TV screens, desktop computers, laptops, tablets, e-readers, smartphones, video games, LEDs, and fluorescent lights all emit artificial blue light. The amount is minimal in comparison to the output found in sunlight. Despite that, the exposure is still significant. That's due to the widespread use of these electronics, the excessive amount of time spent using them, and their proximity to your eyes during use.


Externally, the short wavelengths of HEV blue light scatter easily, which causes more flickering and creates glare. Those issues reduce visual contrast, clarity, and sharpness on your screens, which makes it harder to focus and contributes to digital eye strain. Excessive eye strain can result in headaches, watery eyes, light sensitivity, double vision, fuzzy sight, and the sensation of burning or itching eyes.


Reducing the use of devices and lighting that emit harmful blue light rays is the most effective approach. However, many people rely on their electronic tools for work, resulting in many hours of exposure every day. Plus, it's hard to avoid indoor LED and fluorescent lighting that contributes to blue light emissions.


Blue light filters are tools that reduce or limit the amount of blue light that reaches your eyes. Though they don't block 100% of the blue light you are exposed to, a reduction in blue light exposure helps support your natural sleep cycle and protects against eye strain.


Tinted screen covers, glass overlays, and plastic sheets filter blue light for individual devices. Filtering software and display button settings can minimize some blue light emissions for various electronics. Yet, these options are limited, and none address LED and fluorescent lighting.


These glasses have a tinted protective coating that limits the amount of blue light that reaches your eyes. They work in most settings with any blue-light emitting device. They're also called computer glasses, blue light blocking glasses, and blue light glasses.


Blue light glasses help protect your eyes, visual acuity, and health by screening a percentage of the blue light you come in contact with. They let you and your family enjoy your digital devices and use artificial LED and fluorescent lighting without worry of excessive harmful blue light exposure. They're a portable and affordable option that offers versatility and flexibility, unlike blue light filters, which are tailored to specific devices.


Blue light glasses help lessen your exposure to harmful blue light. With this protection, you can perform professional, educational, and recreational activities on your electronic devices without fear of excessive damage from blue light emissions. Digital protection glasses let you engage in essential and leisure pursuits worry-free, as they shield your eyes from harmful blue light.


Exposure to artificial blue light emitted from electronics and indoor lighting can confuse your internal clock and lower melatonin levels, both of which make you feel more awake, and this can be harmful at night when you're supposed to be winding down for sleep.


If you use digital devices at night, blue light filter glasses can block misleading signals to your body, helping you fall asleep when you're ready. JINS SCREEN Night Use can block 60% of artificial blue light that would otherwise signal your body to decrease melatonin levels. Instead, normal production of this restful, natural sleep hormone continues, supporting your internal clock for a good night's sleep.


Yes. Just add blue light filtering to your progressive lens order. When placing your order with JINS, select the dropdown menu under "Lens Option" and choose between JINS SCREEN DAILY USE, JINS SCREEN HEAVY USE, and JINS SCREEN NIGHT USE for your personalized needs.


Photochromic lenses respond to external lighting conditions, changing shade as required, whereas tinted lenses maintain their permanent tint in all settings. Therefore, you may choose either feature with your blue light glasses but not both. 041b061a72
