2. Redness.
Another common sign of both infectious and noninfectious keratitis is the redness of the eye. In the beginning, the redness will be mild; almost pink in color. As the condition progresses, however, the redness will become more pronounced; it may look as if your eye is bloodshot.
Reddening of the eye can be a sign of several other ailments, including pink eye, or a simple irritation; but, if you have noticed that one or both of your eyes is/are red in color, and you are experiencing any of the other symptoms listed here, then you should make an appointment with your health care provider as soon as possible.
Infectious and noninfectious keratitis can lead to severe and long-lasting eye and vision problems if the condition is not treated properly. Home remedies, such as eye drops, may help to relieve the redness; however, they will not treat the underlying cause.
