Keratitis is an inflammation of the cornea, the clear front part of the eye. This condition can be caused by infections, injuries, or exposure to harmful substances. Symptoms often include redness, pain, blurred vision, and sensitivity to light. If left untreated, keratitis can lead to serious complications, including vision loss. Treatment for keratitis typically involves antibiotic or antiviral eye drops, depending on the cause. It's essential to see an eye care professional if you experience symptoms, as early diagnosis and treatment can help prevent further damage to the eye. Maintaining good hygiene and protecting your eyes can also reduce the risk of keratitis.
