Injuries involving the eyelids can be serious because the eyelids protect the eyes and keep them moist, acting like windshield wipers to wash away foreign matter. An injured eyelid can lose its ability to cover the eye adequately, resulting in drying of the eye, infection, or clouding of the normally clear cornea. After trauma, the eyelids may swell dramatically. A black eye results from blood collecting beneath the loose skin of the eyelids. The tear ducts, which lead from the eyes to the nose, may also be damaged by trauma to the eyelid. Injury to the tear duct interrupts the normal drainage of tears. Proper surgical repair is necessary to maintain normal eyelid function and tear drainage.

What To Do if There's something wrong

For harmfull chemicals in your eyes:
Flush the eye(s) with water immediately! Hold the injured eye open with your thumb and forefinger. At the faucet or with a pitcher or other clean container, flush the eye with a lot of water. Start at the inside corner and pour downward to the outside corner. This lets the water drain away from the body and keeps it from getting in the other eye. Keep pouring the water for 10 to 30 or more minutes. Flush the eye with water until you get medical help. If both eyes are injured, pour water over both eyes at the same time. Or, flush one eye with water at a time. Switch back and forth quickly to treat both eyes. Or, place the face in a sink or container filled with water. Tell the person to move his or her eyelids up and down and remove the face from the water to take breaths. Use this method if chemicals get in your eyes and you are alone. Loosely bandage the eye with sterile cloth and tape. Don't touch the eye. Get Medical Care Right Away!
