In addition, the sophisticated store will also measure the nose height, nose width, the distance between the eyes and ears, and the forward angle of the frame, which are also indicators of whether the glasses are comfortable to wear. It is recommended to try them on after they are fitted, and the time to try on them should be longer, so as to determine whether the glasses are suitable.

When wearing, you can look at the electronic screen far away, and check if there is a sense of irritation to the eyes. The biggest difference between the regular lens and the anti-blue lens is the coating layer. If you look carefully, you can see that the anti-blue lens layer is very clear. Put the anti-blue light glasses on the fully open phone screen and observe if the covered area is blue. If it is, the prevention effect is good. This is because the blue light emitted by the phone is reflected on the phone screen by the lens.
How to test a blue-light lens?

Of course, with the development of technology, now some brands have produced 1.71 refractive indexes blue-light-blocking lenses, suitable for people with high myopia to wear. The true lens package should at least have the product name, refractive index, dispersion coefficient, transmittance, color, SPH, CYL, and other indicators. These indicators are perfect, can be treated as the reference basis of the formal product. In addition, you can go to a professional optical shop or testing institutions for testing.
