If a player wishes to wear additional eye protection with an approved helmet, what must be true?

The correct answer emphasizes the importance of safety standards in sports equipment. For a player to wear additional eye protection with an approved helmet, the eye protection must be NOCSAE (National Operating Committee on Standards for Athletic Equipment) approved and specifically designed to be used with that helmet. This requirement ensures that the eye protection meets established safety guidelines and is compatible with the helmet, which is crucial for the player's safety during play.

Using equipment that is not NOCSAE approved could lead to inadequate protection and increase the risk of injury. Additionally, eye protection that is not designed for a specific helmet might not fit properly or could interfere with the helmet's functionality, further compromising player safety.

While the other options may seem plausible, they do not align with the established safety protocols that protect athletes. Ensuring that any additional equipment meets these standards reinforces the commitment to safety in sports.
