We’ve all heard of this elusive ‘blue light’, but how important is it? With our work and everyday lives involving more and more electrical devices, the presence of blue light is becoming a regular occurrence. This also means the risks to our eyes, energy levels, and overall health are increasing. So, it’s an important issue to discuss!
But, with blue light-blocking lenses, we can protect our eyes no matter where we are or what we’re doing. And with multiple options such as blue light prescription lenses, blue light tinted lenses and even blue light blocking for your designer frames, there’s no excuse not to be wearing blue light glasses.
What is blue light, and where does it come from?
Blue light has actually been around for billions of years, as it’s a natural light ray from the sun. These days, the most common and persistent exposure to blue light comes from electrical devices such as smartphones, TVs, laptops, and gaming computers — the things we use and stare at daily!
Blue light has a short wavelength and an incredibly high energy, which can be just as harmful as UV light. So, we should either reduce our screen time (which is always recommended) or protect our eyes from blue light while using devices.
How do blue light-blocking glasses work?
Blue light-blocking lenses block out the blue light emitted to your eyes. At Lensology, our blue light lenses block UVA and UVB rays, bouncing the harmful rays away and preventing them from reaching your eyes.
The new range of Blue Light Blocking Glasses from Lensology is non-prescription, meaning they’re suitable for any screen user, including adults and children. If you require a prescription lens, don’t worry — our blue light-blocking protection can be added to prescription lenses, too.
How do blue light-blocking glasses help my eyes?
One easy way to protect your eyes from daily exposure to blue light is by wearing blue light-blocking glasses. Not only will they support your eye health, but they also have lots of additional benefits. Here are nine reasons why you should be wearing blue light glasses:
1. You’re investing in long-term eye protection
Some studies have shown that blue light exposure can weaken eyes and damage retina cells. This not only impacts the quality of sight but can also cause problems as we age. By wearing blue light lenses, we can help shield our eyes and extend our visual health.
2. Prevent eye strain
If your eyes start to feel tired and heavy from staring at a screen for too long, you’re experiencing eye strain. This can lower energy levels and harm your eyes — blue light can contribute to eye strain, so you’ll soon notice your eye comfort increasing by opting for blue light lenses or digital lenses with blue light protection built in.
3. Improves sleep
Blue light can disrupt your circadian rhythm — your body’s internal clock that helps you function during the day and sleep at night. Late-night screen scrolling can make your circadian rhythm think the day is still going on, so your mind keeps running, and you can’t fully switch off for a good night’s rest. If you have to view screens late at night, blue light glasses can help reduce some of that impact.
4. Reduce the chance of dry eyes
Dry eyes can be incredibly uncomfortable and a problem when concentrating or trying to give someone your full attention. They can also be dangerous when driving, as you find yourself constantly rubbing your eyes, irritating them further. Blue light-blocking lenses make activities more enjoyable and reduce the need for eye drops to hydrate your eyes!
5. Relief from headaches
Are you noticing more and more headaches the longer you’re working with or looking at a screen? One cause of headaches can be due to extended periods of blue light exposure. Whether you require prescription lenses or not, blue light-blocking glasses are an easy and effective way to relieve headaches. You should also take regular breaks away from your screen, benefiting your eyes and head.
6. Enjoy blue light prescription lenses
Blue light protection can easily be applied to far and shortsighted prescription lenses. If you require prescription glasses for close-up work or wear computer glasses, then adding a blue light coating to your lens is a quick and easy enhancement to keep your eyes protected. But if you require glasses for longer distances or driving, blue light protection can be equally beneficial as it also protects against artificial and natural blue light.
7. Enhance Your Sunglasses
Do blue light lenses work in sunglasses? Absolutely! How often do we stare at our phones to get the perfect holiday snap? Or perhaps you have the luxury of working on your computer outside in the sunshine. Either way, adding blue light-blocking lenses to your sunglasses is a brilliant solution to protecting your eyes from UV, UB and blue light.
8. They can fit into ANY style of glasses frame
One of the biggest advantages of blue light-blocking lenses is that they can fit into ANY shape, size or style of glasses frames. This means you don’t have to spend money purchasing a new pair of frames; you can simply reglaze your lenses with Lensology, and we’ll fit your new and improved blue light lenses into your specs.
From Dior, SunGod, and Ray-Ban glasses to polarised, Transitions®, and bifocal lenses, Lensology offers a simple solution for enhancing glasses and sunglasses and protecting your eyes from blue light.
9. Wear them anytime
Blue light lenses don’t impact your line of sight, meaning they can be applied to any type of frame (including designer brands), different prescription needs, and even sunglasses. No matter where or how you use digital devices, you can enjoy worry-free viewing, knowing your eyes are always protected with blue light-blocking glasses.
Can I wear blue light glasses whilst driving at night?
Yes! Blue light-blocking lenses can help improve your vision while driving during the day or night. Blue light can be emitted from natural sources (sunlight) and artificial sources (dashboards, satnavs, etc.). So, by wearing blue light lenses or prescription blue light lenses, you can keep your eyes protected while helping reduce eye fatigue and headaches.
What can you do about blue light exposure?
There is a lot of high-quality research about screen time exposure, with recommendations for children and adults. It’s recommended that children under five don’t exceed an hour of screen time and a maximum of two hours for older children (Source: World Health Organisation). Whilst there are no set adult screen time recommendations, the advice is to spend no more than two hours before detrimental impact occurs.
What we do know is that this is most certainly not possible with work commitments and the challenges brought to the world in 2020 by COVID-19. Adults spend over 40% of their time a day on a screen device of some kind. That’s a whopping 6.25 hours a day and 45 hours a week! (Source: OFCOM).
You can take active measures to keep an eye on screen time and usage, but blue light-blocking glasses are a fantastic tactic for alleviating the impact on your health.
