Frequently Asked Questions
What is a face shield?
Face shields are personal protective equipment devices that are used by many workers (e.g., medical, dental, veterinary) for protection of the facial area and associated mucous membranes (eyes, nose, mouth) from splashes, sprays, and spatter of body fluids. These shields are generally not used alone, but in conjunction with other protective equipment and are therefore classified as adjunctive personal protective equipment. Although there are millions of potential users of face shields, guidelines for their use vary between governmental agencies and professional societies and little research is available regarding their efficacy.
Can I use a face shield instead of a face mask?
According to experts, face shields are not a viable alternative to masks on their own, but they can provide extra protection to other parts of the face when used with a traditional mask.
“Eye protection is good, which you don’t get with a face mask,” said Dr. Daniel Morgan, M.D., a professor of epidemiology and public health and infectious disease at the University of Maryland School of Medicine. “A mask should be worn to cover the mouth and nose.” According to Morgan, there is little data to support the use of face shields without a mask, so they should not be used as a replacement for more traditional face coverings. The Centers for Disease Control and Prevention (CDC) also does not recommend face shields as an alternative to face masks , though does note that “some people may choose to use a this type of shield when sustained close contact with other people is expected.” The CDC says face shields should wrap around the wearer’s face and extend past the chin.
While a face shield can help protect the wearer from large splashes or droplets to the eyes, they usually do not completely cover the sides of the face or under the chin, which leaves room for airborne particles to find their way underneath the shield.
“[Their design] makes them more comfortable, but allows respiratory droplets and small aerosols, possibly containing virus, to escape into the surroundings,” said Dr. Scott Segal, chair of anesthesiology at Wake Forest School of Medicine. “A covering with some ability to trap particles or filter them out is what’s really needed.”
How to select a face shield?
Face shields are meant to be used as barrier protection for the facial area and associated mucous membranes from airborne body fluids (blood, saliva, bronchial secretions, vomit, urine, etc.) expelled as a result of various physiological processes (vomiting, coughing, sneezing, etc.). The selection of the most appropriate face shield model(s) will depend on the circumstances of exposure, other PPE used concurrently, and personal vison needs. Shields with single Velcro or elastic straps tend to be easiest to don and doff; doffing can be accomplished with a single hand. In order to be efficacious, these shields must fit snugly to afford a good seal to the forehead area and also to prevent slippage of the device. Visors manufactured from acetate, propionate, and polycarbonate offer improved visual clarity and optical quality with the potential for less eye strain. Face shields should be selected that have visors treated for anti-glare, anti-static, and anti-fogging properties. For improved protection from infectious agents, these shields should be, at a minimum, full face length with outer edges of the shield reaching at least to the point of the ear, include chin and forehead protectors, and cover the forehead. Cost-effective considerations include disposable shields vs. reusable models and those that offer replaceable parts.
Face shields are not meant to function as primary respiratory protection and should not be used alone because aerosols can flow behind the visor, so a protective facemask (medical/surgical mask, N95 FFR, etc.) should be worn concurrently.
Should you get a face shield?
“A face shield is good against the really big stuff [particles] that you can kind of see,” he said. “But as the stuff gets smaller and smaller, it’s just easy for that to go around the shield and be inhaled.” Shields can also be bulkier than masks, said McKnight, making it more uncomfortable for the wearer (and consequently more likely for them to take it off). Keep in mind that shields also don’t meet the criteria for a face covering in all states, so you’ll need to check your local requirements before wearing one in public without a mask.
