A corneal abrasion is a scrape or scratch on the cornea. The cornea is the clear, protective covering at the front of the eye, and it is the first part of the eye to refract light. The cornea contains several nerve endings just beneath its surface. When these nerve endings are disrupted or damaged, severe pain can result. Symptoms vary from person to person, depending on the severity and location of the abrasion. Corneal abrasion symptoms include: Pain, typically severe, Photophobia (sensitivity to light), Feeling like a foreign object is in your eye, Watery eye, Impaired, blurry, or hazy vision, Redness in the sclera (the white part of eye), Crusty or fluid-like discharge from affected eye, Excessive squinting, Swollen eyelids, or Enlarged pupils.
