Minor cornea scratches typically heal on their own within a few days, while more severe scratches take longer to heal. Antibiotic eye drops or ointment may help prevent an infection in the event of a scratched cornea. A scratched cornea is also referred to as a corneal abrasion.
Tips to help with a corneal abrasion while the eye heals include not wearing contacts until the eye is completely healed, wearing sunglasses to help mitigate pain from glare and avoiding rubbing the eye. Most people experience a full recovery from a scratched cornea without permanent eye damage. Symptoms of a scratched cornea may include feeling like there is sand in the eye, eye pain, tearing and redness, sensitivity to light or blurred vision.
