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. On the college level, a tinted eyeshield may be used if the player has eye problems. The NFL requires a waiver by the trainer and a doctor to wear tinted or reflective visors.
