Are Blue Light Blocking Glasses Worth It?

What are blue light blocking glasses? Do they work? Are they worth it? We'll answer all these questions in our article this week from our Calgary eye clinic.

You most likely know that staring at a digital screen is bad for your eyes and doing so can damage them. But do you know why that is? If not, let us be the first to tell you that it's because of the blue light these screens emit. 

So what is blue light? Blue light is a short wavelength, high energy form of light that is visible. The sun emits it, but so too do our cellphones, tablets, laptops, and computers. While our eyes do a pretty good job of blocking out the ultraviolet and infrared rays the sun gives off, and we have things like sunscreen and sunglasses to further protect our eyes from the sun, the one form of light our eyes aren't good at blocking out is, you guessed it, blue light. 

But do blue light blocking glasses work and are they worth the cost? The short answer is yes, so long as you buy them from your optometrist. There are currently tons of online stores selling so-called blue light blocking lenses that don't perform as advertised. As always, it's buyer beware. 

Let's look at some of the main reasons why legitimate blue light blocking glasses are definitely worth the investment and how they can help protect your eyes and vision.

Blue Light Blocking Glasses Are Definitely Worth It

When we head indoors, some of us falsely believe that our eyes are safe from any damaging rays. In reality, especially given how often we're on our digital devices and staring at screens, our eyes are at risk of suffering damage from the blue light we outlined above. But there is a solution: blue light blocking glasses. 

Think of blue light blocking glasses like sunglasses for when you're inside. When you wear them when you're watching TV or scrolling through your phone, the amount of blue light your eyes are exposed to decreases. By doing this, you can expect to see the following short-term and long-term benefits:

Short-term benefits

  • The ability to focus longer
  • A reduction in digital eye strain and its accompanying symptoms
  • A reduction in headaches

Long-term benefits

  • Lowering your potential risk of developing retinal diseases like macular degeneration
  • Better sleep (blue light can disrupt our circadian rhythm)

Not All Blue Light Blocking Glasses Are Made Equal

If you've made the decision to better protect your eyes from the damaging effects of blue light while at home or work, then a quick online search will reveal thousands of glasses to choose from. But be warned that not all blue light blocking glasses are made equal.

The ones you find online can differ greatly in their efficacy from the ones your optometrist has at their clinic. Like with most things, you really get what you pay for. While some blue light blocking glasses can be bought online for only $10, you should be suspicious of glasses that cost so little. And if you've already bought a pair of blue light blocking glasses, be sure to bring them to your optometrist for them to inspect. They can tell you whether or not the glasses will actually protect your eyes from blue light, or if you've unfortunately fallen for a slick marketing campaign.

By purchasing legitimate blue light blocking glasses, you can help protect your eyes from the damaging effects of this short wavelength, high energy form of light and improve your sleep in the process.

Q: Can you wear blue light glasses all day?

Yes, there are no negative side effects associated with wearing blue light blocking glasses all day. In fact, you will protect your eyes even more from the harmful effects of blue light, especially those that are emitted by the sun.

Q: Can you wear blue light glasses while driving?

Certainly. Clear blue light blocking lenses are actually your best bet to cut down on the damaging effects of blue light while driving, and when they're paired with anti-reflective and anti-glare coatings, your eyes will also be protected from the glare emitted by headlights.

Q: How do you know if you need blue light glasses?

The most obvious sign that you need blue light glasses would be if you suffer from frequent headaches after using your digital devices. If you find you have trouble sleeping because of your digital device usage before bed, then blue light glasses can also help with that.
