Are Your Glasses Blue Light Blocking? Here’s How to Tell

In today’s digital age, screens are everywhere—laptops, smartphones, TVs, tablets, even e-readers. With all this screen time comes one big question: do you need blue light glasses, and how can you tell if yours are the real deal?

Blue light blocking glasses are designed to protect your eyes from the high-energy blue-violet light emitted by screens, which can contribute to digital eye strain, fatigue, and even long-term vision issues. But with so many products on the market, it’s important to know whether your glasses are actually blue light filtering glasses—or just regular lenses in disguise.

Let’s dive into how to check if glasses block blue light, what features to look for, and how to make sure you’re investing in a quality pair.

How to Tell If Glasses Are Blue Light Filtering

When shopping online, it’s easy to be unsure about whether the blue light blocking glasses you ordered are legitimate. Many budget-friendly retailers—especially on big platforms like Amazon—sell “computer glasses” that look stylish but don’t always live up to their promises.

Sometimes these sellers include a blue light test card or a small UV flashlight as a “proof” of blue light filtering. While this might look convincing, these quick tests don’t always reflect real-world performance, and the credibility of the seller can be questionable.

The most reliable way to know if glasses are truly blue light filtering is to purchase from a trusted, professional optical brand. Established eyewear companies, such as EFE Glasses, design their blue light blocking lenses with expert-developed coatings that undergo real optical testing. Buying from a reputable brand ensures you’re actually getting the eye protection you’re paying for.

Do Blue Light Filtering Glasses Have a Tint?

One of the most common questions shoppers ask is: “Do blue light glasses have a yellow tint?” The answer depends on the type of glasses and the level of blue light protection.

• Computer glasses for heavy screen use often come with a noticeable yellow or amber tint. These block a very high percentage (65%–99%) of blue light, making them especially popular among gamers and people who spend hours in front of multiple monitors.

• Everyday blue light blocking glasses used for work, study, or casual screen time usually feature a subtle—or even invisible—coating. Thanks to advancements in lens technology, modern blue light lenses now look almost identical to regular eyeglass lenses, without the distracting yellow hue.

At EFE Glasses, our blue light glasses for work and gaming are designed to give you all the protective benefits without altering your vision or your style. They’re available in prescription blue light lenses and non-prescription blue light glasses, so everyone can enjoy healthier, more comfortable screen time.
