When welding flashes to the eyes, the condition is called electrophthalmia, which is caused by the ultraviolet component of the welding light damaging the epithelium of the cornea and forming superficial keratitis, with symptoms manifesting as obvious eye irritation, such as pain, photophobia, tearing and vision loss in the eyes. The best treatment for this condition: First, you should stay away from the environment of welding. Second, you can use antibiotic eye ointment inside the eye, which can isolate the eyelid from the cornea, thus reducing the obvious foreign body sensation. Third, you can choose to use drugs that promote corneal repair, such as recombinant bovine basic fibroblast growth factor eye drops. The recovery is generally very fast, with the majority of cases returning to normal in about 24-48 hours, and the prognosis for this condition is very good, leaving no sequelae.
