Different Methods to Test Your Blue Light Glasses

Considering the impact of blue light from digital screens on our eyes and the necessity of digital devices in our everyday lives, blue light glasses are selling like hotcakes. However, that also raises the concern of testing the efficacy of these blue light glasses. You can find many cheap options in the market that rarely offer the right protection required against harmful blue light. In this blog, we’ll talk about different ways to test the efficacy of blue light glasses.

Blue Light Glasses- Do They Really Work?

The only problem that most research and studies mention about blue light glasses is the lack of a proper standard. There is a difference between blue light glasses offered by every brand. The biggest problem is that most brands don’t even mention which wavelength of blue light their glasses can block.

Let’s take a hypothetical situation in which your eyeglasses can block 100% blue light, in that case, you will still suffer from irregularity in your sleep cycle as your eyes won’t get the necessary blue light that they need during the day. That’s why it is crucial that your glasses only block a certain percentage and particular wavelengths of blue light.

For example, our X-Blue lenses are designed to filter blue light, particularly in the 400 to 455 nanometer range where most artificial short-wavelength blue light vibrates. Now let’s look at different methods to test blue light glasses.

Methods to Test Blue Light Glasses

1. Blue Light Blocking Glasses

Spectrometer test: The most accurate and only professional way to test the efficacy of your blue light glasses is using a device called a spectrometer. This test is done inside the lab where the device splits visible light into its original coloured wavelengths. In the next step when you put the lenses in the device, it detects the specific wavelengths that are passing through the glasses and getting blocked. It gives an accurate reading of the percentage and wavelengths of blue light or any particular light that is being blocked.

Some alternative methods you can try at home:

Pigment test: In this method, you need to keep your glasses in front of a digital screen like your laptop. Open a white background and if the screen appears slightly yellowish through the lens that means it filters out blue light. However, you won’t be able to figure out the specific wavelength it blocks with this method.

Reflection test: Another popular method is holding your glasses in front of a light source and looking at the reflection on the lens surface. If you see blue reflection on the lens surface, it means that your glasses can block blue light. However, we can not confirm the authenticity of this method and it doesn’t give you any specific detail for sure.

Wrapping It Up

To be honest, there are not many effective methods to measure the efficacy of blue light glasses at home. The reliable methods include lab tests using tools like spectrometers. However, our blue light lenses feature an innovative design where the blue light filtering material is built into the material of the lens itself. It also comes with anti-reflective coating as standard which further enhances your experience while using digital screens.
