Why Face Shields? By now we know we should be wearing face masks to protect others from potentially deadly infection when we leave the house. But face masks can be hot, and they can irritate the skin, fog glasses, make it difficult for some to breathe and create a world without smiles. It also can be difficult for people who have hearing loss to communicate when mouths are covered, muffling voices and hiding facial expressions.
Are clear plastic face shields, most frequently used in health care settings, a better option?
The Centers for Disease Control and Prevention continues to recommend wearing “cloth face coverings in public settings where other social distancing measures are difficult to maintain.” But some health experts say shields appear to be very effective at preventing infection — maybe even more effective than masks — for someone going about regular daily activities and not in a high-risk health care setting.
Amesh Adalja, M.D., a pandemic preparedness expert at the Johns Hopkins Center for Health Security, says, “There’s a lot of at least biological possibility to suspect that [shields] are definitely better than homemade face masks, and maybe even better than other types of masks as well, because they not only prevent you from spreading it … [and] because it also covers your eyes, it provides more protection to the mucus membranes of your face where you might be getting infected.”
