If you have black eyes is your nose broken?

Not necessarily. Black eyes are caused by bruising around the eyes, which can be caused by a variety of factors including being punched in the eye, getting hit by a ball, or having an allergic reaction. A broken nose is a separate injury that occurs when the nasal bone or cartilage is fractured. While it is possible to have both a black eye and a broken nose at the same time, they are not necessarily related.
