There are many kinds of industrial protective glasses, including dust-proof glasses, impact proof glasses, chemical proof glasses and light radiation proof glasses. The first three kinds of glasses look like colorless glass, but in fact, due to different protective effects, the characteristics of the lenses are obviously different.
Some workers engaged in industrial production need to wear glasses. Wearing such glasses is not for decoration and fashion, but to protect their eyes from harmful factors. Therefore, such glasses are called safety glasses.
Workers engaged in electric welding, gas welding, steel making and glass blowing shall wear anti arc radiation glasses. However, the lens color of anti arc radiation glasses is dark and light, which is designed according to different requirements. The selection should be properly selected according to the intensity of arc during operation. Strong arc light and dark color; Light color lenses should be selected, otherwise. If the arc light is strong, wearing light protective glasses, some infrared rays will stimulate and damage the eyes through the lens, and will suffer from occupational cataract in the long run; On the contrary, if you wear dark safety glasses for a long time due to weak arc light, your vision will be greatly reduced.
Dust proof glasses are used in dusty environment, and the requirements for the fastness of general lenses are not high. Whether the eye mask type or flat lens type, they are made of general flat glass lenses. The anti impact glasses are used to prevent small particles from flying from hitting the eyes. Their lenses are required to be impact resistant. For example, lathe workers, sanders and stonemasons should wear anti impact glasses. If these workers wear general dust-proof glasses, the iron sand and gravel flying glasses will be broken, and the eyes will be more damaged.
The lenses of chemical resistant glasses are acid-base and corrosion-resistant, which other glasses do not have.
