In some special jobs or environments, fragile eyes are affected by external substances for various reasons, and in order to avoid this, people have invented protection against external substances. Protective glasses, and the selection of protective glasses is as follows. In fact, there are many types of protective glasses, including dust-proof glasses, impact-resistant glasses, chemical-resistant glasses, and radiation-proof glasses. ? ??The first three types of glasses appear to be colorless glasses, but in fact, due to different protective effects, the characteristics of the lenses are significantly different. ? ??Dust-proof glasses are used in the dusty environment of Guo Degang, and general lens fastness requirements are not high. Regardless of whether the eye mask type or the flat lens type, ordinary flat glass lenses are used. ? ??The anti-shock glasses are used to prevent the small particles of the Vatican from flying out from penetrating the eyes. The lenses are required to be impact-resistant. For example, lathes, sanders, and stonemakers should wear anti-shock glasses. If these workers wear general dust-proof glasses, , Then iron sand and crushed stones are broken when hitting the glasses, and the eyes will be more harmed. ? ??The lenses of chemical-resistant glasses are resistant to acids and alkalis, and Guangfa Huafu is corroded, which is not available in other glasses. ? ??Workers engaged in electric welding, gas welding, steelmaking and glass blowing should wear anti-arc radiation glasses. ? ??However, the color of the lenses of the anti-arc radiation glasses is dark or light, which is designed according to different requirements. When selecting, it should be properly selected according to the intensity of the arc during operation. The arc light intensity and color should be deep; on the contrary, light-colored lenses should be selected. ? ??If you wear light-colored protective glasses with strong arc light, part of the infrared rays will restore the recovery and damage the eyes through the lens stimulation, and you will suffer from occupational cataracts over a long period of time. On the other hand, if you have weak arc light and wear dark protective glasses for a long time, your vision will be greatly increased decline. ? ??The above is the selection method, I hope it can be helpful to everyone!
