Now more and more jobs are beginning to cause damage to our eyes. We need special protective glasses to protect our eyes, such as surgical glasses used in hospitals, welding glasses used during electric welding, UV protective glasses, etc. different protective glasses are required for different occasions, also known as labor protection glasses. So many kinds of protective glasses, how should we choose
1. There are many kinds of safety glasses, including dust-proof glasses, impact proof glasses, chemical proof glasses and light radiation proof glasses. The first three glasses look like colorless glass, but in fact, due to different protective effects, the characteristics of the lenses are obviously different.
2. 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.
3. 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.
4. 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.
5. 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 stonecutters should wear anti impact glasses. If these workers wear general dust-proof glasses, iron sand and gravel will be broken when flying glasses, and their eyes will be more damaged.
6. The lenses of chemical resistant glasses are resistant to acid and alkali and corrosion, which other glasses do not have. Therefore, every worker who needs to wear protective glasses should understand the harmful factors of his working environment, wear appropriate safety protective glasses and do not wear them indiscriminately.
