In many special workplaces, substances that are harmful to the eyes can be generated. In order to protect the eyes, protective glasses for certain substances are needed, such as welding protective glasses required by welding personnel, medical protective glasses required by doctors in hospitals, There are also the most common sunglasses. 1. 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 arc-proof radiation glasses is dark or light, which is designed according to different requirements. The selection should be appropriately selected according to the intensity of the arc light during the operation. The intensity of the arc light and the 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 stimulate and damage your eyes through the lenses, and you will suffer from occupational cataracts in the long term; on the other hand, if you have weak arc light and wear dark safety protective glasses for a long time, your vision will be greatly reduced. ? ??2. There are many types of safety protective glasses, including dust-proof glasses, impact-resistant glasses, chemical-proof eyes, and light-proof radiation 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. ? ??3. Anti-impact glasses are used to prevent small particles from flying out from penetrating the eyes. The lenses are required to be impact-resistant. For example, lathes, sanders, and stonemakers should wear anti-impact glasses. If these workers wear general dust-proof glasses, Then iron sand and crushed stones are broken when they hit the glasses, and the eyes will be more damaged. ? ??4. Some workers engaged in industrial production need to wear glasses for operation. Such glasses are not used for decoration and fashion, but to protect the eyes from harmful factors. ? ??5. Dust-proof glasses are used in a dusty environment, and the general lens fastness requirements are not high. Regardless of the eye mask type or flat lens type, ordinary flat glass lenses are used. ? ??6. The lenses of chemical-resistant glasses are resistant to acid and alkali, and corrosion, which is not available in other glasses. ? ??Therefore, every worker who needs to wear protective glasses should understand the harmful factors of his working environment, wear appropriate safety protective glasses, and don't wear them all.
