Safety protective glasses are a kind of glasses that play a special role, and different occasions require different glasses. Such as surgical glasses for hospitals, welding glasses for welding, laser protective glasses for laser engraving, and so on.
Glasses are also known as labor protection glasses in industrial production. They are divided into two categories: safety protective glasses and protective masks, which are mainly used to protect the eyes and face from the radiation of electromagnetic waves such as ultraviolet, infrared and microwave, and dust and smoke.
, Metal and sand debris, and chemical solution sputter damage.
There are many types of safety protective glasses, including dust-proof glasses, impact-resistant glasses, chemical-resistant glasses, and radiation-proof glasses. The first three types of glasses appear to be colorless glasses, but in fact, due to different protective effects, the lens's
There are significant differences in characteristics.
Some workers engaged in industrial production need to wear glasses for operation. They are not worn for decoration and fashion, but to protect the eyes from harmful factors. Therefore, these glasses are called safety glasses.
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 anti-arc radiation glasses is dark or light, which is designed according to different requirements. The selection should be based on the arc when working.
The strength and weakness and appropriate choice. The intensity of the arc light and the color should be deep; on the contrary, light-colored lenses should be selected. If arc light is worn with light-colored protective glasses, part of the infrared rays will stimulate and damage the eyes through the lenses, and will cause occupational cataracts in the long term;
Conversely, if the arc light is weak and wearing dark safety protective glasses for a long time, the 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. Generally, the fastness requirements of the lenses are not high. Regardless of the eye mask type or flat lens type, ordinary flat glass lenses are used. The anti-shock glasses are used to prevent small particles from flying out.
For eye use, its 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, iron sand and crushed stones will be broken when they hit the glasses, and the eyes will suffer Greater loss
harm. The lenses of chemical-resistant glasses are resistant to acids and alkalis, and are corrosive, which is not available in other
