Most office workers spend a long time dealing with computers. This will undoubtedly cause eye fatigue. In order to protect our eye health, a new type of anti-radiation anti-radiation eyewear was launched. For the general public to better buy satisfactory anti-fatigue glasses, Chongqing optometry experts with glasses to discuss some of the buying skills. First, the choice of lens type. There are two kinds of lenses for radiation protection glasses, one is a coated lens and the other is a synthetic lens. The advantage of the coated lens is that the process is simple and the cost is low. The disadvantage is that the radiation resistance is relatively low, and only 30-50% can be prevented. It is not durable, and the surface coating layer is easy to wipe off. Synthetic lenses are multi-layered electromagnetic, reflective lens layers vacuum synthesis. The advantages are durability, good light transmission, strong impact resistance, and high anti-radiation rate of 99.9%. The disadvantages are complicated process and high cost. Second, the choice of lens quality. This takes into account the transmittance of the lens, the thickness of the lens, the weight of the lens, and the stiffness of the lens. In general, optical lenses with multilayer antireflective films, colorless optical lenses, and aspherical ultra-thin optical glasses The transmittance of the sheet is better, and the glass lens is heavier than the resin lens. Glass lenses have higher hardness and wear resistance than resin lenses. The resin lens is stronger than the glass lens, and the impact resistance is not easy to be broken. The specific choice of the lens can be decided according to each person's needs. Finally, choose from the feeling after wearing. Since radiation-resistant and fatigue-resistant lenses have radiation protection layers, when we wear them, especially when we look at computers for the first time, we obviously feel that the vision is very clear and natural. The usual kind of dazzling and slightly beating of the monitor will disappear completely. The better the lens quality, the more obvious this effect will be.
