How to Test Blue Light Glasses: A Comprehensive Guide

How to Test Blue Light Glasses: A Comprehensive Guide

Have you ever wondered why some of your friends rock glasses with a slight tint, even indoors? They’re not just a fashion statement. They’re blue light glasses, a must-have for many of us glued to screens all day. You see, these nifty little specs are designed to filter blue light, that pesky wavelength our devices emit that can mess with our eyes and sleep patterns.

Now, if you’re like me and love a late-night Netflix binge or Insta-scroll, you might’ve felt that all-too-familiar digital eye strain or found counting sheep harder than your econ final. That’s where blue light glasses come in. They’re like a barrier between your eyes and your screen, potentially easing the strain and helping your body wind down when it’s time to hit the hay.

Identifying Different Types of Blue Light Glasses

So there’s a whole spectrum of blue light glasses out there, and picking the right pair is tricky.

Comparing Clear, Yellow, Orange, and Red Lenses

Let’s break it down. We’ve got clear lenses, which are perfect for you fashionistas. They’re almost invisible and block a modest amount of blue light, so they’re great for your day job.

Yellow lenses are a step up, cutting out more high-energy blue light, and they give you that cool, intellectual vibe. Red and orange lenses, though, are the heavyweights. These are for the serious screen addicts and can help big time with sleep hormones because they block much more of that blue light that keeps our brains buzzing.

But remember, the darker the tint, the less you’re meant to wear them in natural lighting, similar to how wearing sunglasses at night is not good for your eyes or your fashion sense.

At-Home Testing Methods for Blue Light Glasses

If you’ve ever wondered how legit your blue light glasses are, you’re not alone. For those of us who don’t have a lab tucked away in our back pocket, there are some pretty neat tests at home that can give us the lowdown on our lenses.

The Transmittance Spectrum Report: Understanding Manufacturers’ Blue Light Blocking Claims

First things first: Let’s talk about spectrum reports. These documents are packed with info on what wavelengths your glasses can block and to what extent.

Most reputable brands will provide these reports, but if yours didn’t, just shoot them a quick email asking for the deets. Once you get it, look for high percentages of energy blue light blocking – ideally in the 400 to 450-nanometer range, where the blue light from screens hangs out.

DIY Test: The Blue Sky Method for Clear Lens Glasses

For clear lens glasses, try the blue sky test. It’s straightforward: Put on your glasses and look up at a clear blue sky. If the sky loses some of its blueness and turns a bit grayish or greenish, your glasses are working. If not, they might not be effective.

The RGB Color Wheel Test for Sleep Glasses

Now, for the bedtime blue light blockers: the RGB color wheel test. You’ll need to pull up an RGB color wheel on your screen; there are loads online. Look at the blue section through your glasses. If they’re doing their job, that blue should look dim or downright appear black. The more it changes, the better you’re blocking that sleep-disruptive blue light.

The Black and Blue Circle Test: A Visual Confirmation

Another one for the books is the black and blue circle test. Grab a piece of paper, draw two circles – one black, one blue – and stare through your lenses. If the blue circle looks black, or at least darker, you’re golden. No change? Might be time to reassess those specs.

Reflection and Pigments Tests: Exploring Additional Methods

Some extra tests to double down on your detective work:

Reflection Test for Daytime Glasses

The reflection test is a go-to for daytime glasses checkers. Hold your glasses up to a screen and look for a reflected color, often blue or purple. That’s the anti-blue-light coating showing off. If it’s clear, your glasses might not be doing as much as you think.

Pigments Test for Nighttime Glasses

For nighttime glasses, the pigments test is your BFF. Use a blue light (like from an LED) and shine it on a white surface through the glasses. If the light turns a different color, like red light or orange light, your lenses are absorbing the blue. If it’s still looking blue, it’s a no-go.

Understanding Professional Testing Standards

Now let’s pull back the curtain on how the real pros test those blue light glasses. It’s not just about looking cool or feeling a difference. There’s some serious tech involved to ensure your glasses are up to scratch.

The Role of Spectrophotometers in Accurate Blue Light Testing

A spectrophotometer is an instrument professionals use to measure light transmission. It shoots light through the lenses and reads how much of that no-good blue light is being filtered out. It’s precise and detailed and is the gold standard because it gives us the cold hard facts on what those lenses can really deflect.

Why Some Popular Tests Aren’t Reliable

As savvy as we might be in using at-home tests, it’s important to remember they’re not infallible. Here’s why some of these popular methods can be misleading.

Lack of Standardization

First off, there’s the a lack of standardization. There are no set rules for how brands should test their blue light glasses, which means the results can be varied. One brand’s “blocked” could be another’s “barely budging.”

Narrow Wavelength Range

Then there’s the issue of the narrow wavelength range. Some tests only check a small part of the blue light spectrum. We need to account for the full range if we’re serious about protecting those peepers.

Intensity of Light

Intensity of light is another hurdle. Some tests might throw a high-powered beam at the glasses, which doesn’t exactly mimic the glow of your smartphone. It’s like comparing a sunbathing session to a stroll in the moonlight.

Binary Result

The binary, yes-or-no result of some tests oversimplifies things. We’re not just looking for a thumbs up or down; we want to know how much blue light is being blocked.


Finally, there’s subjectivity. What looks blue to you might look more turquoise to me, and that can skew how we judge the effectiveness of our blue light glasses.

So, while at-home tests are definitely helpful, keep in mind that they only give you part of the bigger blue light-blocking picture.

Further Considerations and Next Steps

If you’ve tried out those at-home tests and your glasses have flunked, don’t sweat. It’s not the end of the eyewear world.

The first step is to reach out to the manufacturer. They might have a warranty or exchange policy. If not, it’s okay to go back to the drawing board. Protecting your eyes is super important, and settling for less-than-stellar specs isn’t the way to go.

Remember: Quality blue light glasses are the best and don’t have to cost an arm and a leg, but they should be effective, comfy, and maybe even complement your killer style. And hey, while we’re chatting about eye health, let’s not forget those regular eye exams. They ensure everything’s okay with your eyes and your vision’s sharp as a tack.

If your glasses didn’t ace the tests, consider finding a better pair. There are many options out there, and finding the right one for you is a journey worth taking. Keep your eyes happy, your sleep sweet, and your digital life as vibrant as ever.
