Welding operations due to cutting welding and other operations, may lead to broken slag into the eye caused by eye laceration, foreign body or endophthalmitis, welding glare irradiation of the eyes, may cause photophthalmitis, macular damage and other hazards. Welding operations due to the steel, stainless steel and other cutting or welding operations, in the case of not paying attention to the protection or protective equipment is too poor quality, the rapid ejection of debris is likely to cause eye trauma, such as corneoscleral laceration, intracorneal foreign body, etc., debris is too dirty, but also triggered by intraocular inflammation, eye pain, vision loss and other clinical symptoms. Most of the welding or cutting is accompanied by bright light, long-term direct light, in the absence of proper protection, can cause electro-optical ophthalmia, corneal epithelial detachment, eye pain, vision loss, bright light damage to the macula can also lead to severe vision loss. Therefore, cutting and welding operations should pay special attention to the protection of the eyes, and seek medical treatment as soon as possible when discomfort occurs.
