corneal disease, a minor problem that can cause you to lose your vision.
The cornea is the front part of the eye that provides clear vision.
The main function of the cornea is to refract light into the eye so that the vision is clear. The cornea also helps protect the eye from dust and germs.
Corneal diseases are abnormalities or inflammation of the cornea, the clear layer at the front of the eye. Corneal diseases can severely affect vision if not treated properly. Some of the more common corneal diseases include:
Corneal abrasion
