A study cited in the Journal of the American Medical Association (JAMA) found that face shields were shown to reduce immediate viral exposure by 96% when worn by a simulated health care worker within 18 inches of a cough (June 9, 2020, Volume 323, Number 22). Shields work by providing coverage around the face. The better the coverage around the face the more protection the shield provides which is why the Humanity Shield stands out.
