Face shield protect the entire face, including the eyes, which along with the nose and mouth can be gateway for the coronavirus and other germs that enter the body. The plastic panel that hangs from the top of the forehead and extends below the chin prevents large respiratory droplets that are thought to carry the virus from reaching these areas of potential infection. When an infected person sneezes, coughs or speaks without wearing a face mask, the viral droplets are spewed all around.
The virus is passed on to other people if these infectious drippings enter the nasal cavity, mouth, or eyes. Where face mask only cover the nose and mouth area, a face shield provides greater protection by covering the eyes as well. With the full-face coverage, from over the top and sides to below the chin, even the smallest infectious droplets are unable to penetrate the plastic shield. It helps protect the wearer’s entire face against the splashes and sprays of fluid-borne pathogens. Therefore, a face shield is quite effective in stopping the viral droplets and saliva from entering the body through the eyes, nose, and mouth keeping the person safe and well protected. Moreover, wearing a face shield in combination with disposable face masks respirators, and other protective equipment can significantly lower the risk of contracting the virus.
