Shiner

A shiner is a colloquial term often used to describe a bruise, particularly one around the eye. When the skin around the eye is injured, blood vessels can break, causing blood to pool in the surrounding tissues. This pooling of blood leads to discoloration, which typically appears as a dark purple, blue, or black mark. As the bruise heals, the color gradually changes, often progressing through shades of green and yellow before fading completely. The term "shiner" is widely understood in informal contexts to refer to this type of injury, regardless of the severity of the underlying trauma. It is a common, though informal, descriptor for periorbital ecchymosis.
