Keratitis is an inflammation of the cornea, the clear front part of the eye. It 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. There are different types of keratitis, such as bacterial, viral, and fungal keratitis, each requiring specific treatments. Maintaining good eye hygiene and protecting your eyes from injury can help prevent this condition. If you experience symptoms, it's important to see an eye care professional for proper diagnosis and treatment.
