What is a subconjunctival hemorrhage?

A subconjunctival hemorrhage is similar to an ordinary bruise on the skin — it’s like a bruise of the eye. It usually appears as a single, concentrated spot of red, or many scattered red splotches, on the white of the eye. The redness is blood under the conjunctiva, a clear membrane that covers the white of the eye (called the sclera) and the inner eyelids.
The conjunctiva contains numerous blood vessels and capillaries, the tiniest blood vessels in the body. These vessels can break, causing blood to leak between the conjunctiva and the sclera. This minor bleeding under the eye’s outer membrane is what causes the bright red spot to appear on the white of the eye.
