WHAT EXACTLY IS A BLUE RAY GLASS?
Due to its very short wavelength and great intensity, blue light produces a flickering movement and glare. Blue light is a part of the visible light spectrum. The eyes’ sharpness, brightness, and visual contrast are diminished when they are subjected to such hazardous glares over an extended length of time.
Blue light can be created artificially or naturally. The eye’s filters do not provide much protection from exposure to artificial blue light, but they do provide some protection from natural blue light. Because of this, using digital equipment, electronics, fluorescent LED lighting, and other lighting that emits such blue light can be bad for your eyes.
WHY DO WE NEED BLUE RAY GLASS
- Blue light is present everywhere; however, our main source is the sun, and we are most exposed to it when we are outside during daylight hours. Man-made sources of blue light include fluorescent and LED lighting, flat-screen televisions, and the display screens of computers, electronic notebooks, smartphones, and other digital devices. The biggest harm is done here, and our kids are particularly vulnerable because they are more likely to spend a lot of time outdoors, whether at school or on the playing field.
- Heightened susceptibility following cataract surgery – Always enquire about the type of intraocular lens (IOL) that will be used to replace your hazy natural lens, as well as how much protection from damaging blue light it offers, from your surgeon. Additionally, you might benefit from wearing eyeglasses with lenses that feature a particular blue light filter, which helps lessen eye fatigue caused by extended screen staring.
- Increased vulnerability post cataract surgery – Always ask your surgeon what type of Intraocular lens (IOL) will be used to replace your cloudy natural lens, and how much harmful blue light protection that lens provides. You may also benefit from eyeglasses that have lenses with a special blue light filter, which contributes to reducing eye strain from staring at screens for too long.
- It causes digital eye strain, which is something we are all susceptible to even though it is less harmful than the impacts of the sun’s blue light. Although it just takes two hours to create digital eye strain, the majority of individuals spend at least 12 hours a day in front of a screen. The effects of gazing at screens for too long include dry eyes, eye strain, headaches, and fatigued eyes. With the use of special computer glasses, blue light exposure from computers and other digital devices can be minimized.
- Blue-ray glasses are specialised glasses that selectively filter such light before it gets to your eyes. In this way, when you use devices while wearing blue light filtering glasses, they reduce the glare and keep your eyes protected.
- Such glasses are technologically advanced and make for the right eyewear choice in today’s digitally driven world. More people are increasingly choosing blue ray glasses to minimise the harmful effects of digital glare and to keep their eyes and vision healthy.
IT’S NOT ALL BAD NEWS
There are quite a few drawbacks to blue light, but it’s also crucial to keep in mind its benefits. For instance, a certain amount of blue light exposure is essential for our general health. Blue light has been shown in studies to control circadian rhythm (the body’s cycle of awake and sleep), support memory and cognitive performance, increase alertness, and enhance mood.
FOR THE OUTDOORS
In the end, however, we must return to the fact that the blue light produced by the sun is by far the strongest and more likely to hurt us, thus simply shielding our eyes from artificial sources is insufficient.
Lens coatings must be used to safeguard eyes by blocking out dangerous blue light while letting in beneficial light. Without impairing your eyesight in any way, this will guarantee ongoing eye protection.
Clear protective lens coatings like Crizal, are perfect for indoor and outdoor use, making it a convenient solution to the harmful blue light.
FOR BOTH INDOOR AND OUTDOORS
Using photochromic lenses, which are clear in low light but turn darken as the light level rises, is another successful technique. Transition lenses provide the best defense against both the sun’s UV rays and the blue light emitted by electronic devices and indoor lighting.
All ages can use these glasses, which is a clear advantage, especially for young children under the age of 12, who are more susceptible to UV damage because their natural protective barriers in their eyes are still developing.
HOW DO BLUE LIGHT GLASSES HELPS THE EYES
- Prevents dry eyes
Dry eyes may sound like a minor affliction but when you are trying to concentrate or about to drive after a few hours working, gaming, or networking online, it is not what you need. Also, increased rubbing of your eyes due to dryness can make them sore and mean you are touching your eyes considerably more than you should. Limit the transfer of bacteria to your eyes and make your screen time more comfortable by blocking out the blue light causing the dryness.
- Relief from headaches
Now again, headaches are not to be taken lightly and you should seek medical advice before self-treating. If you are found to be experiencing headaches due to your blue light exposure through screen time, then Lensology’s Blue Light Blocking Glasses and lenses are a simple and effective way to alleviate headaches.
A welcome addition is an improvement in posture – often impacted by headaches and eye strain and as a result, can be a debilitating side effect of blue light disrupting your daily life.Long term eye protection
Conserving the condition of your eyesight is something we too often do not do. We now know to wear sunglasses in bright sunlight almost habitually. With the digital world around us forever increasing in frequency and format, protecting eyes from the impact it can have seems like a simple step in future-proofing our eyesight for the long term.
- Prevents eye strain
Eye strain can be caused by a variety of issues and so we would always recommend you seek medical/optical advice should you experience it. If it is found to be from digital use then Lensology’s blue-light-blocking glasses and lenses can make a sizable impact on the strain to your eyes, improving concentration and vision throughout the day.
- Improves sleep
By blocking the blue light, the glasses and lenses can therefore halt the disruption to your circadian rhythm as mentioned earlier. It may not be blue light alone disrupting your sleep, but research has found it to have a detrimental impact. By limiting the blue light and ideally not using a screen in bed before you go to sleep (we are all guilty!), you can give your body the restful sleep it needs to function properly, and frankly, it deserves it.
- Blue light lenses can fit in any frames
You do not need to change your frames should you decide to add blue light blocking to your eyecare. If you have the frames you want, Lensology can reglaze your glasses with many different filters and protective glazed lenses including the blue light blocking function. If you are non-prescription, then their new range for children and adults caters for those patients looking for blue light blocking only, with the added features including;
- Blue light blocking
- Anti-glare coating
- Anti UVA and UVB
- Anti- smudge, and fingerprint
- Water repellent
- Dust Repellent
- Reduced colour and image distortion
The impacts of blue light exposure on our health and wellbeing may be managed with a few easy actions, and blue light blocking eye care is an easy and efficient way to achieve this. Blue light exposure isn’t going away; on the opposite.
HOW TO AVOID EYESTRAIN
The AAO recommends the following tips for avoiding eyestrain:
- Keep your distance from screens at about an arm’s length, or 25 inches.
- Look at the screen with a slight downward tilt.
- Give your eyes a vacation by following the 20-20-20 rule, which recommends gazing away from your screen for 20 seconds every 20 minutes and toward an item that is at least 20 feet away.
- If your eyes feel dry, use artificial tears to increase moisture.
- To make a screen comfortable to look at, adjust the contrast levels and the room’s lighting.
- If necessary, use a matte screen filter.
- If you have been issued glasses by an ophthalmologist or an optometrist, wear them when using a screen.
