Keratitis is inflammation of the clear, dome-shaped tissue that covers the eye (cornea). It's caused by infection, injury, wearing contact lenses too long, or some diseases.


Eye redness, pain, irritation, and blurred or decreased vision are symptoms.


Prompt medical attention is needed to avoid loss of vision. Treatment may include medications, including antibiotics or antifungal drugs.
