What can cause a corneal abrasion?
A corneal abrasion can occur when something gets into your eye, such as sand, dust, dirt, and wood or metal shavings. The cornea can also be scratched by a fingernail, a tree branch or a contact lens that is dry or dirty. Rubbing your eyes very hard is another way that an abrasion can occur. In some people, the outer layers of the cornea are weak. These people may get a corneal abrasion for no apparent reason.
