How long for scratched sclera to heal?

Conjunctival injury: When the white of the eye is injured, there is often a superifcial abrasion of the conjunctiva as well as some localized bleeding. This often heals in a few days, although any blood that is present can take a week or two to go away completely.

Few days: The sclera is the white part of the eye, which is covered by a translucent membrane called the conjunctiva. Any scratch to the white part of the eye would scratch the conjunctiva, not the sclera, unless it was very deep - which is much more serious. You should be seen by your ophthalmologist to be sure. Most conjunctival abrasions or corneal abrasions heal within a few days with antibiotic drops.
