Not only are face shields effective at preventing the transmission but they also are easier to disinfect and reuse.
Dr. Kohli said a face shield should be used as an alternative for some people.
Face shields have been shown to reduce viral exposure by 96% when worn within 18 inches of a cough, and by 92% at the currently recommended 6 feet of social distancing, according to a recent editorial in the Journal of the American Medical Association. Dr. Payal Kohli points to a study, face shields are good at preventing exposure because it covers your mouth, nose, and eyes. “So, they’re actually pretty good at protecting the wearer, but the opposite we don’t know yet. Are they good at preventing droplets from getting out? And one of the reasons is because they’re not as tightly fitting to our face,” said Dr. Kohli.
“If you’re somebody who has extreme claustrophobia, you really just can’t tolerate wearing the face mask, that’s probably an acceptable alternative, but if you’re going to do that, remember to maintain that social distancing really keep that six feet of distance from others,” said Dr. Kohli.
