Welding protective glasses is a sharp weapon to protect the health and safety of workers. Compared to ordinary non-protective glasses, welding protective glasses must have something different from it, but do you know the difference? Let's take a look at how to tell whether a pair of glasses is protective. First talk about the material: ? ??1. Compared with other glasses making materials, it has more strength, considerable flexibility, and moderate rigidity, so that it can better meet the needs of welders. ? ??2. Do not use flammable materials, because sparks are often caused in the welding industry. If flammable materials are used, problems are easy to occur. ? ??3. The material of the headgear should be very soft because it needs to be worn for a long time during operation. If you choose hard materials, it will be harmful to the human body. ? Then the structure: ? ??1. The surface of the welding glasses is very smooth, and there are no burrs and acute angles, and there are no other defects that may cause facial discomfort; the same is true of other glasses. ? ??2. The parts of welding glasses are relatively easy to replace, and the adjustable parts are also very flexible; some anti-chemical glasses or anti-impact glasses structures are generally not adjustable. ? ??3. Welding glasses should have good breathability; many sports protective glasses have the same effect. ? ??4. Welding glasses are mostly dark, because dark-colored lenses can better block harmful substances to the eyes, thereby protecting the eyes. Other glasses have different colors due to their different effects.
