A face shield is an item intended for both medical and industrial purposes. Positioned at the crown of the head, it is fitted with plastic to cover the wearer’s entire face and protect it from potential hazards. They offer more coverage than a face mask alone.
Face shields that are intended for medical use are regulated by the FDA under 21 CFR 878.4040 (surgical apparel). They can protect from flying debris and chemical splashes, as well as the spread of infectious materials through bodily fluids.
There are benefits to using face shields in the attempt to contain coronaviruses such as COVID-19. They can be produced and distributed rapidly and affordably. They are reusable and may be cleaned easily with soap and water or disinfectant. Finally they restrict individuals from impulsively touching their own face – an easy way to spread the virus that causes COVID-19.
