An eyeshield is a piece of football equipment. It is a visor that attaches to the helmet of a player to protect the eyes. It leaves the mouth exposed and covers the eyes and nose. Only clear eyeshields are allowed in high school football as the eyes are needed to be seen while checking for concussions. On the college level, a tinted eyeshield may be used if the player has eye problems. The NFL allows dark visors, (smoke or black) and reflective mirror visors, but does not allow colored or iridium visors.
