What is one of the primary functions of face guards in football helmets?

One of the primary functions of face guards in football helmets is to prevent face injuries. The design of face guards is specifically aimed at providing a barrier that protects the facial area from impact and contact during play. Given the physical nature of football, players are at a significant risk of injuries to the face, including fractures, lacerations, and concussions. By utilizing face guards, the helmets help minimize these risks, making them an essential component of player safety equipment.

While improving visibility, attaching to the chin strap, or allowing for customized designs may contribute to the overall functionality or aesthetics of the helmet, these features are not the primary purpose of face guards. The focus on preventing face injuries underscores the importance of safety in sports equipment development and reflects the protective goals of athletic training and player protection protocols.
