Benefits of Blue Light Glasses
Technology is the bread and butter of today’s society. We work, we connect, and we even shop virtually. But, although digital devices are an amazing advancement in our modern age, our eyes might be taking the brunt of it.
Electronics emit what is known as “blue light,” which can be harmful to our eyes. Believe it or not, it only takes about two hours of staring at a screen to cause eye strain, irritation, and headaches. Not to mention, blue light can even disrupt your sleeping patterns and cause you to toss and turn throughout the night. The good news is that blue light glasses are an extremely beneficial option to offset the negative impacts of electronic light.
To give you a better idea of how blue light glasses can help you whether you’re working your nine-to-five from your laptop or playing video games until two in the morning, we’ll discuss all the benefits and how they can add some protection to your beloved peepers.
Let’s jump in!
What Are Blue Light Glasses?
Blue light glasses are equipped with lenses that are specifically designed to protect our eyes from any blue light rays that they encounter. The lenses are a mixture of filtering materials that help block a portion—if not all—of blue light from coming into contact with the bare eye. Many blue light lenses also have glare protection, which can help maintain clear vision.
Although it isn’t proven that blue light directly causes problems for our eyes, it may be a significant contributor to some common issues. That said, blue light glasses can help protect your eyes from the negative symptoms of long exposure.
Benefits of Blue Light Glasses
Amongst the chronic blue light that we experience every day from technology, LED lights, and even long sun exposure, counteracting with blue light glasses may have considerable impacts, not only on our eyes but also on our day-to-day lives. Here are just a few of their potential benefits:
1. They can Reduce the Risk of Eye Damage
Regularly exposing our eyes to blue light can lead to eye damage and even vision problems later in life. Blue light can easily penetrate through our cornea and ultimately hit the retina, where it can cause damage to light-sensitive cells and lead to macular degeneration.
Various light sources emit blue light, including computer screens, mobile devices, certain lightbulbs, and even the sun. Between 400 and 500 nanometers, blue light is a short-wave blue light on the electromagnetic spectrum that puts off a high amount of energy. Researchers have found that peak damage to the retina occurs around 440 nanometers.
Blue light glasses can help add a barrier between the susceptible light-sensitive cells and any blue light waves potentially causing damage.
2. They’ll Help Combat Eye Strain
Chronic screen exposure can lead to digital eye strain, which is eye discomfort that results from long-term exposure to artificial light and other up-close activities. As we stare at our screens, we tend to blink less than we do on average; thus, our eyes are more likely to become strained. Eye strain can show up in different ways, including dry eyes, teary eyes, blurry vision, and even headaches.
Wearing eyeglasses, in general, can help decrease dryness and irritation. But, as blue light can make it more difficult to stare at a screen and concentrate, blue light glasses can also add a layer of protection between your eyes and the screen. They can help add some contrast and make it easier for your eyes to focus, thus, reducing eye strain.
3. They Might Improve Your Sleep
Staring at blue light late into the evening can imply to our minds that we need to stay awake—similar to how the sun tells us that it’s daytime. This suggestion ultimately causes difficulty falling asleep and staying asleep. While our brains begin to release melatonin as we get closer to bedtime, short wavelengths like blue light can delay its release and cause us to lack the sleep hormone necessary to get a good night’s rest.
That said, using an electronic device too close to bedtime can cause issues with our sleeping patterns. But, if it is necessary, wearing blue light glasses at least three to four hours before bed can be a beneficial avenue toward blocking blue light and enabling our minds to induce sleep.
Although it can be tough to remember, taking care of our eyes is essential. And while we’ve transitioned into the digital age, our exposure to blue light may be affecting our daily routines. Fortunately, blue light glasses can help. While our electronic devices aren’t going anywhere anytime soon, welcoming blue light glasses can be a beneficial path toward lessening the negative impact of harmful light waves.
