A plastic shield that covers your face will not protect you from COVID-19 in certain cases.
Recent research concluded that if an infected person sneezes three feet away, the subsequent “vortex rings” will carry infectious particles to the face shield and stick to the edge of the plastic in approximately half a second. And if it just so happens that the person wearing the shield breathes in simultaneously, the wearer has a decent chance of becoming infected.
