Why workers wear protective glasses when welding

We often see workers on the construction site wearing protective glasses on the face when welding. Why?
When welding, the arc emits high heat and brightness, causing direct burns to the eyes. When this kind of arc light shines on the eyes, the cells on the surface of the eyeball will be damaged, and the epidermis will fall off. As a result, a layer of protective film on the surface will disappear. The eyes will feel pain like a knife cut, tears flow, open eyes, fear of light, especially at night, more pain and interest. Medically known as electrooptic ophthalmia. This situation is rare for true welders because they are all trained and know how to protect them. Most of them are assistants who help the job. Onlookers, especially children, are most prone to this kind of injury when they are watching.
After the occurrence of electro-optic ophthalmia, due to the patient's very painful, it will go to the hospital for emergency treatment. In fact, people with this knowledge can quickly find a breast-feeding lesbian if they find out that this happens, and squeeze out some people’s milk into their eyes. The symptoms will soon disappear, and human milk can also be protected. The role of the membrane helps the epidermal cells in the eye grow faster and longer.
Sometimes, when the patient goes to the hospital for emergency treatment, the doctor often gives some anesthetic to stop the pain. This is only an expedient measure. After the anesthetic is spotted, the external stimulus to the eyes loses its sense and there is no protection. This is very dangerous. Every doctor must explain to the patient, wear protective glasses and prevent sand and foreign matter from entering the eyes. Inside, causing new injuries.
When the welder is working, in the absence of protection, do not try to watch the bustle and cause eye damage. This is not worth it.
