Face shields are very effective at protecting the eyes, nose, and mouth from viruses in the air/droplets from people sneezing, coughing around them; as also any direct spills/blood / mucous in the hospitals. They are comfortable to wear and form a barrier that keeps people from easily touching their own faces. They significantly reduce the amount of inhalation exposure.
