Eye pain caused by not paying attention to eye protection while welding is clinically known as electrophthalmic uveitis. The quickest way to deal with it should be: promptly visit the nearest hospital and take medication according to the specific lesion. The main symptoms of eye discomfort caused by electrodes are pain, photophobia, tearing, and foreign body sensation. The reason for this is that the strong light from welding contains a lot of high-frequency light that is ultraviolet in nature. The light hits the corneal epithelial cells and has a killing effect on the cells, which is why ultraviolet light can be used for surface disinfection. The damage to the corneal epithelium leads to massive shedding, which causes severe pain. When welding causes eye pain, if you are close to the hospital, you should go to the hospital promptly and remember not to rub your eyes or rinse them with water by yourself. This will only cause further shedding of epithelial cells due to mechanical rubbing and rinsing; it will also increase the chance of infection. The treatment of electrophthalmia is based on medication, which can cure the majority of patients; only a very small number of cases eventually require surgery. Medication: eye drops or ointments that promote healing of the corneal epithelium are used primarily, along with a small amount of antibiotic drops to prevent infection. Although the patients’ symptoms are all heavy, the regenerative ability of the corneal epithelium is very strong, and it usually takes only 24 hours to heal and 3-4 days of medication to provide complete relief. The misconception of medication is that the child is continually placed on the surface of the eye with anesthetics in order to relieve the pain. This can relieve the symptoms in a few minutes, but the anesthetic itself has the effect of breaking the epithelial cells of the cornea, and further aggravate the condition. After the anesthetic effect (about 1 hour) has passed, the symptoms will be more severe. Therefore, on the first day after the disease, patients must insist on enduring and waiting for the corneal epithelium to heal, and must not abuse anesthetics. And surgical treatment is mainly for those with more serious degree of injury, such as large epithelial detachment of cornea, and those with unsatisfactory effect of medication can choose the coverage of amniotic membrane, and if it causes corneal laceration can choose surgical suturing. In summary, welding eye pain needs to be disposed of as soon as possible at the nearest ophthalmology clinic to avoid delaying the condition or even aggravating it. Once again, it is important not to rub the eye or rinse it; surface anesthetics should not be used during treatment; and most patients will be cured quickly without any sequelae if they insist on enduring the pain for 24 hours.
