4. Symptoms of keratitis include: Red eye Sensation of something, like sand, in the eye Pain Sensitivity to light Watery eye Blurred vision Difficulty keeping the eyelids open When caused by an injury or infection, such as herpes simplex virus, keratitis usually affects only one eye, but both eyes may be affected when keratitis is due to other causes.

5. Viral keratitis

6. Prevention The best way to prevent keratitis is to avoid eye injury by wearing sunglasses and appropriate eye gear as needed. If you have a cold sore, do not put your fingers to your eyes, because that could spread the infection. If there is any suspicion that you have herpes simplex virus, steroid eye drops may be dangerous because they can make this infection worse. Routine contact lens hygiene, a balanced diet and moisturizing eye drops may help prevent other causes of keratitis.
