Knowledge of radiation protection glasses

What are radiation protection glasses? Radiation protection glasses are in the process of processing the lens of glasses, adding some compound substances, and pasting a relevant radiation protection coating on the lens. Please see a brief introduction to the principles and functions of radiation protection glasses. With the improvement of the level of science and technology, the wide application of high technology, although it has facilitated our life, but there is great radiation, endangering our health. Our eyes are fragile, and wearing radiation glasses is an effective measure to protect our eyes. What are radiation glasses? Radiation protection glasses are in the process of processing the lens of glasses, adding some compound substances, and pasting a 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 film of radiation protection glasses use this principle to eliminate some of the radiation by causing the electromagnetic waves of different wavelengths generated on the front and back surfaces of the lens to interfere with each other. Introduction to the principle and function of radiation protection glasses The principle of radiation protection glasses Radiation protection glasses are used to protect against the harm of excessive ultraviolet and other radiation to the eyes. Lenses are made of special glass that reflects or absorbs radiation, but transmits a certain amount of visible light. The lenses are coated with a bright metallic film of chromium, nickel, mercury or silver to reflect radiation; Blue lenses absorb infrared rays, yellow-green lenses absorb both ultraviolet and infrared rays, and colorless lead-containing lenses absorb X-rays and γ rays. For example, common welding glasses have relatively low requirements for the light transmittance of the lens, so the lens color is mainly ink; Laser protective glasses, as the name suggests, can prevent laser radiation to glasses, so the requirements for lenses are very high, such as the selection of light source, attenuation rate, light reaction time, optical density, light transmission effect, etc., different nanometer (nm) lasers need to use lenses of different wavelengths. Features of radiation protection glasses: 1. The lens is flat and has no side effects on vision. It is refined by the world's high-tech vacuum ion coating, which can block electromagnetic wave rays 100%. 2. The lens contains anti-radiation substances, which can absorb low-frequency radiation microwaves and eliminate potential fever, headache, tiredness, dryness and other adverse symptoms of the eyes caused by electromagnetic radiation. 3. It has different penetration and absorption functions for different rays, which can resist reflection and strong light, and the user obviously feels clear and natural after wearing. 4. It is especially suitable for computer workers, people who watch TV, play video games, etc., and can effectively prevent harmful light from damaging your eyes and keep your vision healthy forever. Identification of radiation protection glasses 1. Because the surface of the radiation protection lens is coated with a colored radiation protection film, the film layer is blue, green, gold, etc. The blue-green coating layer belongs to the ordinary anti-radiation coating layer, and the radiation resistance effect can reach about 50% according to the national test, and the high-resistance gold coating layer uses special silver oxide elements, which can reach 90% according to the national test. 2. Put it on the spot and look at the computer to see if there are those different feelings. For example, if you look at a computer without any radiation glasses, you feel that the monitor is particularly dazzling and jumps slightly. If you wear radiation glasses, you will feel that your vision is clear and natural. The famous doctor of ophthalmology said that radiation protection glasses are to add compound medium to the production material in the process of processing the lens of glasses, and then paste the radiation protection film on the lens, which can play a certain filtering role to a certain extent. This is because the radiation from computers and the like comes from electromagnetic waves, which have a certain wavelength and amplitude, and the compound medium and the radiation protection film make use of this principle to make the electromagnetic waves of different wavelengths generated on the front and back surfaces of the lens interfere with each other, thereby canceling out part of the radiation. Maintenance method of radiation protection glasses 1. Take off and wear glasses Please hold the temples with both hands and take them off in parallel directions on both sides of the cheeks. If you take it off with one hand, it will break the balance between the left and right sides of the frame and cause deformation. 2. The folding frame should start from the left Most of the frames are designed to be folded from the left temple, so if the right temple is folded first, it is easy to cause the deformation of the frame. 3. Rotation method If the glasses are placed temporarily, please place the convex side of the glasses facing up. If you place your glasses convex side down, the lenses will be sharpened. 4. How to wipe the lens Use a clean special testing cloth, pay attention to be sure to use your hand to support the edge of the frame on the side of the wipe lens, and gently wipe the lens. Avoid damage to the frame or lenses due to excessive force. 5. When the lenses are stained with dust or dirty, dry wipe is easy to wear the lenses, it is recommended to rinse with water and then use a paper towel to absorb the water and then dry it with a special glasses cloth. When the lenses are dirty, it is recommended to wash them with a low-concentration neutral detergent and then rinse them with clean water and wipe them dry. 6. Please use the glasses case When you are not wearing glasses, please wrap them in glasses cloth and put them in the glasses case. When storing, please avoid contact with corrosive materials such as insect repellents, toilet cleaning products, cosmetics, hairspray, medicines, etc., otherwise it will cause deterioration, deterioration, and discoloration of lenses and frames. 7. When the glasses are deformed, the deformation of the frame will cause a burden on the nose or ears, and the lenses are easy to loosen. It is recommended to go to the professional store regularly for plastic adjustmentArticle title: related knowledge of radiation protection glassesArticle editor: glasses.com:。
