I have 20/20 vision with squinting and glasses,but my doctor says i have scarring in my cornea. should i worry?

Corneal scarring: Scarring can be located in the central or the side. Since our central vision is most critical then the location of the scar is also important. But why do you have the scar(s) Is it from corneal trauma or contact len's infections that is permanent or from a corneal problem that may be progressive in 1 or both. Have your ophthalmologist answer that question ASAP Keep us posted. Thoughts? Dr.Sibley
