The short answer is no. According to the CDC, a face shield should be used in addition to a face mask, and not in place of one. The reason: a face shield is primarily used for eye protection, hence the use of face shields in manufacturing and construction facilities. When worn on its own, a face shield doesn’t form enough of a seal around your nose and mouth to truly block out harmful particles. While plastic shields are a great barrier for splashes and sprays, wearing one alone does not provide adequate protection of your airway. – September 25, 2020 RS
