In the manufacturing and processing industry, substances harmful to the human body may be generated due to processing. Taking the eye as an example, in order to reduce the harm, it is necessary to wear corresponding protective glasses. There are four types of protective glasses commonly used in the industry: impact protection, dust protection, radiation protection, and chemical resistance.
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.
??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.
??Dust-proof glasses are used in dusty environments, 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.
??The 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 stone are broken when they hit the glasses, and the eyes will be more damaged.
??The lenses of chemical-resistant glasses are resistant to acids and alkalis, which is not available in other glasses.
