A face shield is a protective piece of equipment that covers the face and provides a barrier from potential hazards. It is commonly used in medical and industrial settings. Synonyms for face shield include visor, facial mask, protective shield, safety helmet, full-face shield, and eye shield. These terms are often used interchangeably, but each can refer to a specific type or style of protective gear. For instance, a full-face shield may refer to a mask that covers the entire face, while a visor may only cover the eyes and nose. Protective shields and safety helmets may also refer to similar gear used in construction or other hazardous environments.
