Corneal scarring, a condition marked by scar tissue on the cornea, can stem from infections, injuries, or even severe dry eye. This scarring may cause blurred vision, light sensitivity, and halos around lights. Diagnosing corneal scarring involves visual acuity tests, slit-lamp exams, and corneal topography. Prevention is key, including proper eye protection and prompt treatment of infections. Find expert resources to help you maintain clear and healthy vision by addressing corneal health proactively.
