Blue Light Glasses: What Do They Do?

By now you are probably familiar with the term, blue light glasses.

Ever since 2020 forced us to transform our lives and spend extra hours at home, we’ve all been spending more time using digital devices than we’d like to admit.

For this reason, many individuals began turning to blue light glasses.

But what do blue light glasses actually do?

In this post, we’ll be revealing what blue light glasses do and why you should consider getting yourself a pair (if you haven’t already)!

Blue Light Glasses: What Do They Do?

Before diving into what blue light glasses are and what they do, let’s take a look at a typical routine in today’s digital world:

7:00 AM Your alarm rings on your phone.

7:10 AM After hitting snooze a few times, you’re finally awake and looking at all of the notifications on your phone.

7:15 AM You might respond to some urgent messages or emails, and after that, you probably open up Facebook or Instagram to check even more notifications. Maybe you even glance at the latest news updates.

9:00 AM You open up your laptop at work and stare at the computer until lunch.

12:00 PM During lunch, you check some more notifications while texting your friends.

12:30 PM You’re back at your desk looking at your computer again until it’s time to head home.

6:00 PM You stop at the gym to work out on your way home and track your workout on your Apple Watch.

7:00 PM You get home and relax by turning on your favorite show for the rest of the evening.

10:00 PM You get into bed and check up on social media or watch a few videos before going to sleep.

Does this look familiar to you?

While your day may not look exactly like the one outlined above, you get the idea: You’re spending a lot of time looking at digital screens.

You might be wondering why all of this excess screen time is even a cause for concern. Allow us to explain.

Why Should I Care About Blue Light

Blue light is a color in the visible light spectrum that sits at the very edge of the spectrum, close to invisible light. Its short wavelengths mean that it hits your eyes at a higher frequency than other colors in the spectrum.

Blue light isn’t all bad.

Some exposure to natural blue light (like the sun) is necessary for your body to maintain a healthy circadian rhythm. A functioning circadian rhythm tells your body when to go to sleep, and when to wake up in the morning.

However, when you expose your body to excessive amounts of blue light (like spending too much time in front of digital screens), you are overexposing your eyes to something that is both unnatural and harmful.

Studies have shown that extended blue light exposure can lead to headaches, sore or watery eyes, and even lead to insomnia. Luckily, these harmful side effects can be prevented by simply wearing blue light glasses.

What are blue light glasses?

Blue light glasses, or sometimes referred to as blue light blocking glasses, are glasses that contain specially manufactured lenses designed to reduce the amount of blue light that reaches your eyes.

What do blue light glasses do?

These special lenses filter out or absorb blue light rays that are emitted from digital devices before they reach your eyes. In addition to protecting your eyes from blue light, they protect your body from all of the symptoms that go along with it.

When should I wear blue light glasses?

Contrary to popular belief, blue light glasses can actually be worn at all times of the day – even when you’re not looking at a digital screen. Check out this blog post for some frequently asked questions about blue light glasses, and the answers to them!
