Full Frontal Protection
Wearing a face shield in addition to a mask may provide additional protection as you may be in closer proximity to others indoors while traveling, at work or school.
"Face shields address two key means of preventing coronavirus transmission: They provide a barrier to respiratory droplets (which, according to the CDC, can occur when a person coughs, sneezes, or talks) and help wearers avoid touching their face. In addition, unlike masks and N95 respirators, they cover the eyes as well as the mouth and nose, allow for easier communication, and are more easily cleaned (with just soap and water or household disinfectants) for reuse. They provide a better barrier to respiratory droplets than cloth face masks, but should be used with a mask for protection from airborne virus."
