Wearing a Face Shield Medical can protect people from contracting Covid-19. Shields are a vital and preventative safety measure. Many people are using these protective barriers to improve their safety when out in public. Shields are comfortable to wear and can keep people from touching their face, mouth or eyes. Plus, they can be disinfected after every use. Shields should be worn by infected people to prevent spreading of the virus. However, healthy individuals can also benefit from wearing shields. Medical shields can stop viral droplets from being dispersed into the atmosphere when an infected person talks, coughs or sneezes. Face masks only cover the mouth and nose. Shields cover the entire face as well as the eyes. They offer a better defense because droplets cannot penetrate the plastic. A face shield is very effective and can also be worn with face masks for increased protection.
