A black eye often results from injury to the face or the head, and is caused when blood and other fluids collect in the space around the eye. Swelling and dark discoloration result in a "black eye" – sometimes called a "shiner." Most black eyes are relatively minor injuries. Many heal on their own in a few days, but they may signify a more serious injury. Despite the name, "black eye," the eye itself is not usually injured. The tissues around the eye may be significantly discolored and swollen without any injury to the eye itself, like a bruise (ecchymosis) around the eye.
The skin around the eye is very loose, with mostly fat underneath it and fluid accumulates easily in this area. The skin around the eye is one of the first places to swell when the facial area is injured. Depending on the location and type of injury, one or both eyes may be affected. Injuries to the eye brow and forehead area often result in black eyes because gravity pulls the blood and inflammatory fluid into the soft tissues under and around the eyes.
As a black eye heals, the swelling around the eye decreases, and the bruise gradually fades away. The bruising will usually start out a very dark purple, and as it fades, it may change to light purple, then greenish, then yellow before disappearing.
The most common cause of a black eye is a blow to the eye, nose, or forehead. Depending on where the blow lands, one or both eyes may be affected. A blow to the nose often causes both eyes to swell because the swelling from the nasal injury causes fluid to collect in the loose tissues of the eyelids.

Edema (swelling) and pain are the most common signs and symptoms of a black eye. Initially, the swelling and discoloration may be mild. The eye often starts off slightly reddened, and then progresses to a darker shade and swelling increases. Some blurry vision or difficulty opening the eye may occur, but more serious visual problems are less common. Over the course of a few days, the area becomes lighter and the swelling decreases. Signs of a more serious injury are double vision , loss of sight, or inability to move the eye. Loss of consciousness, blood or clear fluid coming out of the nose or the ears, blood on the surface of the eye itself, or persistent headache can also indicate a severe injury.
