Disease analysis: The strong light generated during electric welding will burn the corneal surface, causing congestion, pain, photophobia, tears and so on. Because there are abundant nerve endings on the corneal surface, the irritation symptoms will be obvious after injury. It is best to use drugs that promote corneal healing, such as Befushu eye drops or Suyan ointment, and use tobias eye drops or ofloxacin eye drops to prevent infection. When going out, you'd better wear sunglasses to reduce light stimulation, and pay attention to light diet and eye rest.
