Blue light glasses have become increasingly popular due to their ability to protect eyes from the harmful effects of blue light emitted by digital screens. If you’re looking to understand how to identify whether your glasses block blue light, this guide will help you navigate the different ways to check, what to look for, and the importance of blue light protection. In this article, we will cover how to tell if your glasses are blue light glasses, what features they have, and how to make sure they provide the protection your eyes need.
1. How Can You Tell If Your Glasses Are Blue Light Glasses?
Blue light glasses are designed to filter or block blue light, which is known for causing eye strain and sleep disruption. So, how can you tell if your glasses are blue light blocking? The most reliable way to check is by looking at the lens coating or checking for specific features in the frames and lenses. But here’s the kicker: it’s not always as easy as it seems. You might be wondering how to differentiate between blue light glasses and regular prescription or sunglasses. Here’s a breakdown of how to tell if your glasses are truly designed to block blue light.
There are several signs to look for when checking your glasses. One of the simplest methods is the phone screen reflection test.

There are several DIY tests you can do at home to check for blue light blocking properties. What’s the real story here? Let’s explore some easy methods to confirm the effectiveness of your glasses.
The first simple test is the phone screen reflection test. When you look at your phone screen through the lenses, you should see a slight yellowish tint reflected in the lens. This is because blue light blocking glasses often use a yellowish filter to absorb or reflect blue light. If you notice this tint, your glasses might be blue light blocking.
Another test is the flashlight or UV light test. You can use a UV flashlight or blue light source to check how much light passes through the lens. If the light is significantly blocked or filtered, you can be confident that your glasses are blue light protection glasses. But here’s the kicker: while this test works, it’s not always a perfect indicator, so don’t rely on it solely.
Some manufacturers also provide a blue light filter certification, which can be found on the packaging or even on the glasses themselves. These certifications ensure that the glasses have undergone proper testing and meet the required standards for blue light protection.
