Face Shield PVC

Face shields have a number of advantages over masks, they added. First of all, they are endlessly reusable, simply requiring cleaning with soap and water or common disinfectants. Shields are usually more comfortable to wear than masks, and they form a barrier that keeps individuals from easily touching their own faces.
 
Also when speaking, people sometimes pull down a mask to make things easier but that isn't necessary with a face shield.
 
Also the use of a face shield is also a reminder to maintain social distancing, but allows visibility of facial expressions and lip movements for speech perception.
 
In a simulation study, 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.
 
When the study was repeated at the currently recommended physical distancing distance of 6 feet, face shields reduced inhaled virus by 92%.
