Face Shields Are An Achievable Way To Provide Protections That COVID-19 Demands

The COVID-19 pandemic presents enormous challenges. A newly emerged virus to which the world’s inhabitants has no immunity, coupled with the fast movement of individuals throughout the globe, has set the stage for an outbreak of proparts not seen in the last century.

For an infection with this virus to occur, it must come into contact with the eyes, nostril, or mouth. This happens when droplets produced by an infected person (by way of talking, coughing or sneezing), land on the face of one other person. These infectious droplets can travel as much as 6 feet, which is the reason to promote social distancing. Touching a surface that's contaminated with infectious droplets and then touching one’s own eyes, nostril or mouth, is one other way for infection to occur. Therefore, the key to avoiding an infection is to have these areas of the face covered.


In hospitals, face masks and goggles are typically used to forestall exposure to infectious droplets. However, face mask shortages are occurring because of interruptions within the provide chain, which is deeply rooted in China and disrupted by the pandemic. Some health care workers have been pressured to resort to scarves and bandannas in a final-ditch try to protect themselves while providing care. Even when plentiful, face masks usually are not without problems. Once they change into wet from the humidity in exhaled air, they lose effectiveness. In addition, some people contact their face more often to adjust the mask, which will increase the risk of an infection if the arms are contaminated.

Fabric masks, though better than nothing, have been shown to be less protective than medical-grade face masks.

We imagine that face shields provide a better solution. There are lots of types, but all use clear plastic material connected to a headpiece to cover the eyes, nostril and mouth, thereby preventing infectious droplets from contacting these areas where the virus can enter the body. They cover more of the face than masks and prevent the wearer from touching their face. Importantly, face shields are durable, might be cleaned after use, reused repeatedly, and for many individuals are more comfortable than face masks. Because these shields are reusable and are diversified throughout the provision chains of a number of industries, the present supply is less limited than for face masks. They will even be made at house with gadgets from office provide and craft stores.

Each health care worker wants a face shield for protection at work. While face masks are still needed in some situations, implementation of face shields will greatly reduce the necessity for face masks and lengthen the limited nationwide supply of masks. Engineers have produced designs for face shields which might be within the public domain, and fabrication at scale is relatively simple. To ensure that each health care worker has a face shield, production might want to ramp as much as meet the demand by way of present manufacturers and recruitment of additional factories. Because the design is easy, large rapid production would not be difficult.

As soon as the health care workdrive is provided, distribution to the public should begin, with a goal to provide a face shield to every individual within the country. It must be worn anytime an individual leaves their house, while in any public place, and even at work. Although shelter-at-house approaches are wanted to "bend the curve" of this pandemic, the ensuing societal disruption limits the time that political leaders are keen to maintain such measures. Once each individual is shielded, however, reducing restrictions on movement would carry less risk. Universal shielding might reduce reliance on social distancing since infectious droplets cannot attain the face of vulnerable individuals. Handwashing, however, would remain essential to keep individuals from infecting themselves with virus found on the palms after touching contaminated surfaces.
