When choosing protective glasses, users should pay attention to choosing eye and face protection products that meet the relevant national management regulations, have complete marks, and have passed the inspection. .
Choose protective glasses according to the type, roughly divided into dust-proof, impact-proof, chemical-proof glasses and anti-radiation glasses, etc. The protective glasses selected should be qualified by the product inspection agency, and the width and size of the glasses should be suitable for the user’s face.
Workers engaged in industrial production, some need to wear protective glasses to operate, wearing these protective glasses is not for decoration, fashion, but to protect the eyes from harmful factors. Therefore, this type of glasses is called safety glasses.
Workers engaged in electric welding, gas welding, steel making, and glass blowing should wear protective glasses against arc radiation. However, the color of the lenses of the arc-proof radiation glasses is dark and light, which is designed according to different requirements, and the selection should be based on the strength of the arc during operation.
The intensity of the arc light and the color should be dark; otherwise, light-colored lenses should be selected. If the arc light is strongly worn with light-colored goggles, part of the infrared rays will stimulate and damage the eyes through the lens, and occupational cataracts will occur in the long term; otherwise, the arc light is weak and long-term wear of dark safety glasses will greatly reduce vision.
Therefore, every worker who needs to wear protective glasses should understand the harmful factors of his working environment, wear suitable protective glasses, and don’t wear a pass.
Protective glasses are mainly used to prevent chemical damage to eyes caused by irritating or corrosive solutions. Ordinary flat lenses can be used, and the frame should be covered to prevent splashing of the solution. Usually used in laboratories, hospitals and other places, it is generally more appropriate to choose goggles than protective glasses.
Dustproof glasses are used in environments with a lot of dust. Generally, the fastness of the lens is not high. Whether it is an eye mask or a flat mirror, it is made of general flat glass lenses. The anti-impact glasses are used to prevent the small particles from flying out from piercing the eyes. The lenses need to be impact-resistant. For example, the mechanics, sanders, and stone workers should wear anti-impact glasses.
If workers wear general dust-proof glasses, then the iron sand and crushed stones will be broken when flying the glasses, and the eyes will be more damaged. The lenses of chemical-resistant glasses are resistant to acids and alkalis and corrode, which is not available in other glasses.
