What is the purpose of face shields or goggles with three-quarter helmets?

The purpose of face shields or goggles when used with three-quarter helmets is to provide additional face and eye protection. While three-quarter helmets offer coverage for the top and back of the head, they leave the face exposed. Face shields and goggles serve as a barrier against debris, wind, and insects, which can significantly improve rider safety and comfort. They help to prevent injuries to the eyes and face, which are more vulnerable if unprotected.

In high-speed scenarios or adverse weather, having proper eye protection is crucial, as it helps maintain visibility and shields the eyes from elements that could obstruct a rider’s ability to see clearly. The other options may relate to riding comfort or experience but do not directly address the primary function of face shields and goggles in enhancing safety through protective coverage.
