    The most accurate instrument to test blue light blocking is a lab-grade spectrometer. It can detect the degree of anti-blue light of the lens. You can take the glasses to your eye doctor or a professional optical shop to test the blue light glasses. If you think it is troublesome, here are some tips to help you test and recognize blue light glasses at home.

    1. The lenses of blue light glasses are always yellow-tinted to absorb blue light. Therefore, when you place the glasses on a white background, you can see the lens is yellow-tinted compared to the white background. If the color of the lens is close to the white background, it means the glasses are not blue light blocking, or it only can filter about 5% to 20% blue light.

    3. The above methods are for the clear lens blue light glasses. If you get a pair of amber or orange-tinted blue light glasses, you can test the lens in the following way. There are two squares in the picture. One is black, and the other is dark blue. If the glasses are blue-light-blocking, both squares should be black. But if the dark blue square is still blue, the glasses cannot filter enough blue light.
