Do radiation glasses work? How to choose radiation glasses?

Whether it is life or work, we can't do without the computer, but it facilitates our life, but the powerful electromagnetic radiation erodes our body over the years. Especially the eyes, it is very fragile, so many people want to buy radiation glasses to protect their eyes. However, we should be careful and wary of inferior products, which not only cannot protect the eyes, but will cause dry eyes, fatigue, vision loss and other problems. Do radiation glasses work? How to choose radiation glasses? 1. Are radiation glasses useful? Do radiation glasses work? Everyone has such a question, radiation protection glasses are in the process of processing the lens of glasses, adding some compound substances, and pasting the relevant radiation protection coating on the lens. Because the radiation of computers and the like is caused by electromagnetic waves, generally speaking, electromagnetic waves have a certain amplitude and wavelength. The compound medium and radiation protection film of radiation protection glasses use this principle to eliminate electromagnetic radiation by causing different wavelengths of electromagnetic waves generated on the front and back surfaces of the lens to interfere with each other. Looking at the radiation protection glasses market, especially today, when online shopping is so developed, everyone is buying radiation protection glasses online, but everyone must have more eyes. As the saying goes, you get what you pay for, and now the price of good radiation protection glasses that are sold online is basically above 50, and when the merchant sells it significantly lower than the market price, everyone has to choose carefully, if you buy a fake, it is not only useless, but also very serious and irreparable! In order to avoid everyone buying inferior radiation protection glasses, we recommend the radiation protection glasses brand with a very good reputation in the market for your reference, radiation protection glasses: /fangfusheyanjing/ Second, how to choose radiation protection glasses correctly? The ranking of radiation protection glasses brands on the market is dizzying, and how to choose a suitable pair of radiation protection glasses has become a headache for many consumers. There are two types of radiation protection glasses, one is coated and the other is synthetic. The surface coating lens is to coat a reflective film on the surface of the lens, which can reflect and cancel the radiation; Synthetic lenses are vacuum synthesis of multiple layers of lens layers that derive electromagnetic and reflective lenses. When you wear radiation glasses on the spot and look at the computer, you will feel a little different. For example, if you look at a computer without wearing any radiation glasses, you feel that the monitor is particularly dazzling and jumps slightly; If you wear radiation glasses, you will obviously feel clear and natural vision. Tips for buying radiation protection glasses 3. How to detect the authenticity of radiation protection glasses? The quality of radiation protection glasses is uneven, and there are many ordinary glasses with the gimmick of radiation protection. How to distinguish whether glasses can really protect against radiation requires the help of professional testing instruments, but the price is expensive. Industry insiders introduced a few simple ways to distinguish whether the lens is radiation-proof, you only need to look at the light color in the spectacle lens to know, there are three common ones, one is white light, then it does not have the function of radiation protection; the second is blue light, which has the function of radiation protection; There is also a green light, most of the time the store will introduce this is a double antibody (anti-radiation, anti-ultraviolet), but you have to first determine whether the lens is aspherical (the lens is spherical and aspherical) If it is aspherical, then the function of radiation protection will be stronger.。
