Radiation protection glasses are used to protect eyes from excessive ultraviolet and other radiation. The lens is made of special glass, which can reflect or absorb radiation but can transmit some visible light. The lens is plated with bright chromium, nickel, mercury or silver metal film, which can reflect radiation; Blue lenses absorb infrared rays, yellow-green lenses absorb ultraviolet rays and infrared rays, and colorless lead-containing lenses absorb X rays and gamma rays. For example, the common electric welding glasses have relatively low requirements for the transparency of the lenses, so the color of the lenses is mainly ink; Laser protective glasses, as the name implies, can prevent the laser from radiating to the glasses, so the requirements for lenses are very high, such as the choice of light source, attenuation rate, light reaction time, optical density, light transmission effect and so on. Different nano-lasers need to use lenses with different bands.

How can anti-radiation glasses distinguish between true and false?

1. Because the surface of the radiation protection lens is coated with a blue radiation protection film, when you pick up the glasses and shake them left and right, some blue light will shine on the lens surface. Compared with ordinary glasses, ordinary glasses don't emit any shining light.

2. Put it on the spot, watch the computer and see what's different. For example, when I watch the computer without wearing any radiation protection glasses, I feel that the monitor is particularly dazzling and slightly jumping. If you wear "God of Protection" radiation protection glasses, you will obviously feel clear and natural.

Professor Gao Jiansheng, doctoral supervisor of Ophthalmology Branch of Chinese Medical Association, introduced that radiation-proof glasses, that is, in the process of lens processing of glasses, adding composite media into the production materials and then sticking radiation-proof films on the lenses, can play a certain filtering role to a certain extent. This is because radiation such as computers comes from electromagnetic waves, and these waves have a certain wavelength and amplitude. Composite media and anti-radiation film make use of this principle, so that electromagnetic waves with different wavelengths generated on the front and back surfaces of the lens interfere with each other, thus canceling some radiation.

Maintenance method of radiation-proof glasses

1, glasses

Please hold the temple with both hands and take it off in the parallel direction on both sides of your cheeks. If you take it off with one hand, it will destroy the left and right balance of the mirror frame and cause deformation.

2. The folding frame should start from the left.

Most frames are designed by folding from the left temple, so if the right temple is folded first, it is easy to deform the frame.

3. Rotation method

If the glasses are temporarily placed, please put the convex surface of the glasses up. If you put the convex side of your glasses down, you will wear the lenses.

4, the way to wipe the lens

Use a clean special test cloth, be sure to hold the edge line of the frame by hand and gently wipe the lens. Avoid damaging the frame or lens due to excessive force.

5. When the lens is dirty by dust or dirt.

Dry-rubbed lenses are easy to wear, so it is recommended to use paper towels to absorb water, then rinse with clear water and dry them with special glasses cloth. The lens is dirty, so it is recommended to clean it with low-concentration neutral lotion, and then rinse it with clear water to dry.

6. Please use the glasses case.

When you don't wear glasses, please wrap them in glasses cloth and put them in the glasses case. Please avoid contact with insect repellent, toilet cleaning products, cosmetics, hair gel, medicines and other corrosive substances. When stored, otherwise it will cause deterioration, deterioration and discoloration of lenses and frames.

7. When the glasses are deformed

The deformation of the mirror frame will burden the nose or ears, and the lens is easy to loosen. It is recommended to go to a specialty store for plastic surgery regularly. The key to radiation protection glasses is the lens.

Kemi and EOMA are both good shots.

Bao Dao's glasses are not bad, but they are expensive. YOOFACE fashion optical shop Jinji computer eye protection glasses are all good.
