Eye swelling and puffy, swollen eyelids can result from being struck in the eye such as from a baseball moving at a high speed. The best immediate treatment for this type of eye injury is an ice pack.
Remember, you may have a simple black eye (bruising around the eye), but you should see an eye doctor to make sure there is no internal damage. Remember that seeing well out of the eye is an important sign that chances are no immediate serious injury has occurred. However, very often blunt injury to the eye can set in motion a cascade of events that cause serious damage to the eye in the days or weeks that follow. A flashlight or torch assisted examination at the doctor’s office, or the emergency room is not adequate to determine if the injury has or has not occurred. Insist on a full and detailed examination.
