If the eye has been tearing after being poked and the irritation symptoms are more obvious, the black eye (cornea) may have been injured. The nerves of the corneal epithelium are particularly rich, so after injuring the cornea, the irritation symptoms will be more obvious, including eye pain, eye redness, tearing, photophobia, grinding and other sensations, and you should go to the hospital immediately. If it is a partial peeling of the corneal epithelium, you need to apply antibiotic eye ointment, such as erythromycin eye ointment to bandage the affected eye and follow up the next day, which can heal in 24-48 hours in general and will not affect your vision. If the corneal stroma is injured, regular outpatient review is required, and the recovery process is longer and will leave a scar after healing. If the scar is located in the center of the pupil, it may have a slight effect on vision.
