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.

Seeing a subconjunctival hemorrhage on your eye can be alarming. Yet it is actually a common minor occurrence. It is almost always harmless and will heal on its own. It does not affect vision and generally does not cause pain. There are usually no sensations or symptoms, other than the appearance of the red spot. In fact, you may not even be aware that you have a subconjunctival hemorrhage until someone points it out or you look in the mirror.

Treatment of a subconjunctival hemorrhage is not necessary. Over time, the blood spot will slowly disappear, clearing up on its own. This may take days or weeks, depending on the size of the blood spot. Occasionally artificial tears can make your eye feel more comfortable.
