The most probable thing is that your eyelid will turn blackish/blueish/grayish or a purple-y reddish color. Maybe under your eye too. You might get some blood on your eye, and your eyelid might be swollen. Black eyes are usually just minor injuries, and heal by themselves in about a week or so. If you still have a black eye after a week has passed you must visit a doctor. If you have any of the following symptoms, you may have a more serious injury: -Blurry Vision -Double Vision -Signs of blood clotting -Loss of sight -Persistent headache -Inability to move the eye or large swelling around the eye -Blood or clear fluid coming from the ears or nose -Blood on the surface of the eye or cuts on the eye itself

The reflection is red because of all the blood vessels inside the eye." -http://photocritic.org/red-eye-removal-reduction/
