Face shields are used to protect your eyes, nose, mouth and face from flying objects and liquids. They are not a good substitute for face masks because they do not offer the same protection against COVID-19.

A face shield, an item of personal protective equipment (PPE), aims to protect the wearer's entire face (or part of it) from hazards such as flying objects and road debris, chemical splashes (in laboratories or in industry), or potentially infectious materials (in medical and laboratory environments).
