Understanding Blue Light: Sources and Potential Effects

What Exactly is Blue-Light?

Believe it or not, blue light isn’t a new phenomenon. According to the American Academy of Ophthalmology, while commonly associated with digital screens, blue light is also emitted by fluorescent and LED lights, and even sunlight. It’s part of the visible light spectrum that our eyes can perceive. During the day, blue light can actually be beneficial, helping to boost alertness and regulate our sleep-wake cycles. However, it’s this very stimulating effect that can become problematic, especially at night.

Is Blue Light Harmful to Your Eyes? The Science Explained

The scientific community has varying perspectives on the exact long-term effects of blue light on our eyes. The American Academy of Ophthalmology notes that there isn’t extensive long-term research definitively proving the harm of typical blue light exposure from screens.

However, organizations like the American Macular Degeneration Foundation suggest that blue light may contribute to retinal damage and potentially increase the risk of age-related macular degeneration (AMD), a leading cause of vision loss in older adults. Some studies on animal models, like fruit flies, have shown damage to retinal cells and reduced lifespan with significant blue light exposure.  

While the precise impact on human eyes from everyday screen use is still being studied, there’s a clearer understanding of blue light’s effect on our sleep. Excessive exposure to blue light in the evening can interfere with our circadian rhythm, the body’s natural sleep-wake cycle.

Blue-Light Glasses for Kids

Truth is, kids today are using phones, tablets and computers more than ever before, and at increasingly younger ages, too.

While there are undoubtedly many benefits of introducing your kids to tech, there’s is one serious downside- their little, still-developing eyes are getting too much exposure to blue-light. During the early years of your child’s eye development, their pupils are larger and the lenses are clearer. This allows for greater amounts of blue light to enter their eyes.

A growing body of research shows that, at the very least, overexposure to blue light can cause digital eye strain, headaches, and a lack of deep sleep in children. At the worst, exposure to blue light over time can lead to damaged retinal cells and the early onset of macular degeneration, which can lead to vision loss.

There are many ways to help reduce the symptoms of digital eye strain in your children; in addition to setting clear limits for screen time, you can also protect their little eyes by buying a pair of kid’s blue light blocking glasses. Most companies that sell these glasses for adults also carry children’s sizes, so they shouldn’t be hard to find.

When you’re looking for blue light glasses for kids or young adults, make sure that the pair you choose comes with a carrying case, so they don’t get crushed or damaged when they’re not being worn. Also, be sure that your kid’s blue light glasses are lightweight and comfortable.

Make sure that when your kids reach for their iPhone or tablet, that they also grab their blue light glasses. Help your kids create healthy habits while they’re young, so they can benefit from great vision well into adulthood.

Blue-Light-Blocking Glasses for Gamers

According to the Entertainment Software Association, 60% of Americans play video games, daily- that’s roughly 200 million people active in the world of gaming.

Whether you’re an expert or a casual gamer, video games have become a favorite pastime for people all over the world. And there’s good news for gamers; there are many studies linking gaming to increased perceptual and cognitive performance.

Nevertheless, some research shows that playing video games for an extended period of time can also have repercussions, specifically for your vision. For anyone who has ever played a game for longer than 20 minutes, you’re probably well aware of the strain that this can put on your eyes.

Luckily, there is an easy, inexpensive solution: blue-light blocking glasses made specifically for gamers.

Blue light blocking glasses will help alleviate the annoying symptoms that accompany staring at your computer screen, so you can spend more time beating your matches instead of rubbing your eyes.

Next time you throw on your headset don’t forget to grab your pair of blue light blocking glasses- and prepare to level-up your gaming experience.

Blue-Light Glasses for People with 20/20 Vision

Maybe you’ve gotten LASIK, and you no longer need to wear your prescription glasses. First of all, congratulations! How does it feel being able to see clearly without needing glasses? Pretty good, huh?

But, maybe you also miss accessorizing with your favorite pair of frames. If you haven’t noticed, statement frames are IN- and they’re not going anywhere anytime soon.

If you still like the idea of wearing a cute pair of glasses to the office, blue-light blocking glasses may be just what you’re looking for (and you’re not ~really~ just wearing them for fashion either).

By protecting your eyes from hours of exposure to blue light while you’re working, you’ll both preserve your 20/20 vision AND keep up with the all-the-cool-kids-are-wearing-glasses trend.

Additional Benefits of Wearing Blue Light Blocking Glasses

• Alleviate Discomfort: By wearing blue light blocking glasses while you’re on the computer for prolonged periods, you’ll avoid the exposure to the blue light that causes them to feel tired and strained at the end of the day.
•  Get Better Sleep: It’s advised to avoid using blue-light devices for 2 hours before bedtime, as the high-energy frequency can make it harder to fall asleep. However, wearing blue-light glasses while scrolling on Instagram allows you still enjoy a restful night’s sleep afterwards.
•  Reduce the Risk of Cancer: Recent studies suggest a link between exposure to light at night to certain types of cancer. Research shows that exposure to blue wavelengths can slow down the production of melatonin in our bodies, increasing the risk of cancer. Since blue light glasses block blue rays, it’s believed that by wearing them you can restore normal melatonin production and decrease your chances of getting cancer.
•  Prevent Age-Related Macular Degeneration (AMD): AMD is one of the leading causes of blindness in the U.S. and currently affects almost 11 million people. This occurs when the small, central portion of the retina (the macula) deteriorates. Blue-light glasses can help prevent AMD by protecting the eyes from being damaged by blue light rays.

How to Choose the Best Blue-Light Glasses

So, what makes one pair of blue light blocking glasses better than another? There are over 7000 pairs of blue blocking glasses available on Amazon alone, and the pricing ranges from $7 to $700.

While aesthetics will play into which pair (or two?) you end up with, the key is to find out how much light they block out. The best glasses for reducing blue-light exposure will have high-powered lenses that block up to 90% of blue light.

When you’re looking for the best blue-light blocking glasses, you’ll find that they are typically made with either clear or colored lenses. Clear lenses block around 5% – 40% of the blue spectrum, while yellow lense block between 40%-75% of the blue spectrum, making tinted lenses the more effective method of blocking blue light.

However (while there’s nothing wrong with rocking a pair of Fear-and-Loathing style glasses) most people opt for the clear lenses because of their less obvious lenses.

Orange lenses block 100% of the blue spectrum- which should never be done during the day. Blocking all blue light during the day will completely mess up your circadian rhythm and could, if worn consistently over time, start to alter how your brain functions.

So, which blue-light blocking glasses are the best?

Here’s the bottom line: Whether you’re an avid gamer, or an office worker, you’ll want a pair of glasses that are comfortable and functional- not just trendy.

If you’re buying blue light glasses online, make sure to do your homework:

• Check the return policy
•  Make sure that there are good reviews from happy customers
• Keep an eye out for a certificate which will specify the exact wavelength range that’s being filtered.
• Look for glasses that filter up to 455 nanometers

Additional Ways to Combat Blue Light Exposure & Digital Eye Strain

Today’s society is powered by digital devices- and while it’s not a bad thing, it’s definitely something to be aware. Here are a few easy and applicable ways to help decrease digital eye strain from blue light exposure:

• When you’re staring at a screen, try to blink frequently. This helps moisturize your eyes and prevents dryness and irritation.
•  Take short breaks from staring at your electronic devices. About every 20-30 minutes, get up, stretch, and walk around to give your eyes a chance to rest.
• Clean your screen often. Having a smudge-free, dust-free screen can help reduce the glare.
• Change the background colors on your devices from bright white to warmer colors. Many phones have “night-time” features, and you can set specific times of the day to turn on this feature.
• Use the extension Flux at night to slowly decrease your computer’s blue glow as the sun sets.
• Avoid looking at bright screens for two hours before going to bed.
• Use dim, red lights at night. Red light is the least likely to shift your circadian rhythm and suppress melatonin.
• Make sure your diet is full of healthy foods to promote healthy vision
• Blue light blocking glasses have been proven to protect your eyes from digital eye strain that so many Americans are suffering from. With a little bit of research, you can find the perfect pair of blue light glasses to fit your personality and lifestyle.

Hopefully, this article has provided some answers to the common questions people have when looking to buy a pair of blue light glasses.
