When the eyes are exposed to ultraviolet light, it is called electrophthalmia. In fact, many scenarios can occur, such as not wearing protective goggles when watching welding, or not wearing anti-UV glasses in snow or sea level, causing burns and necrosis of the corneal epithelium, which can lead to pain and foreign body sensation. You can also use drugs that promote corneal epithelial repair, such as Bevosol or recombinant human epidermal growth factor gel, and you can use some eye ointment to reduce friction and foreign body sensation inside the eye. In addition, for pain, local cold compresses can be applied, which have a certain pain-relieving effect on the pain, and if the symptoms are heavy, systemic painkillers can be taken orally, such as Fenbuterol for milder symptoms, and codeine for heavier symptoms, which will gradually reduce the symptoms after 24-48 hours and even heal on their own.
