1, radiation protection glasses adopt international high-tech vacuum ion plating, which can block electromagnetic waves and have no side effects on vision; The lens contains anti-radiation substances, which can absorb low-frequency microwave radiation and eliminate potential adverse symptoms such as fever, headache, fatigue and dryness caused by electromagnetic wave radiation; Radiation-proof glasses can also effectively prevent harmful light from hurting eyes and protect vision health.

My experience is that it's good to use radiation-proof glasses as eyepiece, and it only works with full face radiation protection, because radiation is not just eyes.

2. At present, there are two kinds of radiation-proof glasses on the market, one is coated lens and the other is synthetic lens.

The advantages of surface coated lenses are simple process and low cost, but the radiation protection performance is poor and not durable, and the surface coated layer is easy to erase. The retail price of this kind of radiation-proof glasses is generally 100-200 yuan, even lower than that of some online shopping websites in 30 yuan.

The advantages of synthetic lenses are durability, good light transmission, strong impact resistance and strong radiation resistance, but the cost is high, and the retail price in the market is generally above 300 yuan, even thousands of dollars.

Whether to buy or not, what to buy, be careful when buying.
