A black eye is a type of bruise. Simple bruises are treated with ice and by elevating the head. The bruise should be gone in 2 to 3 weeks.
Apply ice or cold packs for 15 minutes 3 or 4 times a day during the first 48 hours to help reduce swelling. Place a cloth between the ice and the skin. The sooner you apply a cold pack, the less swelling will occur.
Do not use chemical cooling packs. If the pack leaks, the chemicals could cause more eye damage. Do not use a raw piece of meat on a black eye.
Keep the head raised to help reduce swelling.
Be sure to look at the eyeball for possible injury.
