Which face shields are recommended to prevent the spread of COVID-19?

As cases of Covid-19 breakthrough surges, the Centers for Disease Control and Prevention recently updated its recommendations for vaccinated people to continue wearing face shields and masks with exhalation valves.


While you likely have a face mask or ten on hand, there's a good chance you're missing another piece of important personal protective equipment: face shields. Are they more effective than masks? Which face shields are more useful? If you’re looking for more protection or a less restrictive face covering, we’ve consulted medical experts to break down how face shields work and how to best shop for one.


COVID-19 spreads mainly from person to person through respiratory droplets, which travel into the air when you cough, sneeze, talk, shout, or sing. These droplets can then land in the mouths or noses of people who are near you or they may breathe these droplets in.


Masks are a simple barrier to help prevent your respiratory droplets from reaching others. Vitro testing suggests that face shields may provide a better option. Face shields appear to significantly reduce the amount of inhalation exposure to influenza virus, another droplet-spread respiratory virus. 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.


For optimal protection, “Because they extend down from the forehead, shields protect the eyes as well as the nose and mouth,” says pediatric infectious disease specialist Frank Esper, MD. The coverage that face shields offer is ideal since the new coronavirus can enter the body through those points.


But now the market like amazon and other large online retailers is full of face shields with Inferior quality, which are chemical hazard that might become foggy, causing glare, visual distortion or visual strain.


It's near-impossible to spot counterfeit masks, especially when shopping online, but you can choose to buy from reputable retailers, such as MARIFUL, which have vetting processes for products.
