A face shield is a piece of rigid, clear plastic hinged to a headband. The plastic piece is placed on the face, extending to the base of the chin. You might have seen face shields on some health care givers, even before the COVID-19 started to cause havoc.

 Dentists and dental hygienists would wear them when working close to patients’ mouths. Doctors, nurses and technologists might utilize face shields, as well as with face masks, when doing procedures that could put in blood or other substances into the air.
