What do goggles and face shields protect?

Goggles and face shields are designed specifically to protect the mucous membranes of the mouth, eyes, and nose from potential exposure to infectious materials. These areas of the body are particularly vulnerable to contamination, as they can facilitate the entry of pathogens.

Using goggles helps shield the eyes from sprays, splashes, or droplets that may contain harmful microorganisms, while face shields provide a barrier for the entire face, offering additional protection to the nose and mouth. This is especially important in healthcare settings, where exposure to potentially infectious fluids is a risk.

While other options outline areas of the body that may need protection in certain contexts, they do not directly pertain to the specific protective functions of goggles and face shields. Items like gloves or gowns are more appropriate for hand and body protection, while respiratory protection is typically managed through masks or respirators for lung safety.
