Symptoms of Black Eye
After an injury to the eye, it is important to distinguish between symptoms of black eye and those that might indicate a more serious head injury.

Black eye symptoms may include:
pain around the eye
swelling around the eye, which can be mild at first, then increasing later. Swelling may make it difficult to open the eye
discoloration (like a bruise) around the eye. The skin around the eye may be red at first, then grows darker, progressing to purple, yellow, green or black
blurred vision

Signs of a more serious head injury require medical attention, and may include the following:
double vision
vision loss
blood on the eyeball surface
inability to move the eye
severe or ongoing headache
fainting/loss of consciousness
blood or fluid coming from the ears or nose
