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

The COVID-19 pandemic presents monumental challenges. A newly emerged virus to which the world’s population has no immunity, coupled with the rapid movement of individuals across the globe, has set the stage for an outbreak of proparts not seen in the final century.

For infection with this virus to occur, it should come into contact with the eyes, nose, or mouth. This happens when droplets produced by an infected individual (via talking, coughing or sneezing), land on the face of another person. These infectious droplets can journey up to 6 toes, which is the reason to promote social distancing. Touching a surface that's contaminated with infectious droplets and then touching one’s own eyes, nose or mouth, is another way for an infection to occur. Due to this fact, the important thing to avoiding an infection is to have these areas of the face covered.


In hospitals, face masks and goggles are typically used to prevent publicity to infectious droplets. Nonetheless, face mask shortages are occurring because of interruptions in the supply chain, which is deeply rooted in China and disrupted by the pandemic. Some health care workers have been forced to resort to scarves and bandannas in a last-ditch try to protect themselves while providing care. Even when plentiful, face masks are usually not without problems. As soon as they turn out to be wet from the humidity in exhaled air, they lose effectiveness. In addition, some individuals touch their face more often to adjust the mask, which increases the risk of infection if the palms are contaminated.

Material masks, though higher 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 numerous types, but all use clear plastic material hooked up to a headpiece to cover the eyes, nostril and mouth, thereby stopping infectious droplets from contacting these areas the place 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, can be cleaned after use, reused repeatedly, and for many people are more comfortable than face masks. Because these shields are reusable and are diversified throughout the availability chains of a number of industries, the present supply is less limited than for face masks. They can even be made at dwelling with items from office supply and craft stores.

Every health care worker needs a face shield for protection at work. While face masks are nonetheless wanted in some situations, implementation of face shields will enormously reduce the need for face masks and lengthen the restricted national supply of masks. Engineers have produced designs for face shields that are within the public domain, and fabrication at scale is comparatively simple. To ensure that every health care worker has a face shield, production will need to ramp up to meet the demand through current producers and recruitment of additional factories. Because the design is simple, massive rapid production would not be difficult.

As soon as the health care workforce is provided, distribution to the public should begin, with a goal to provide a face shield to every person in the country. It needs to be worn anytime an individual leaves their house, while in any public place, and even at work. Although shelter-at-dwelling approaches are wanted to "bend the curve" of this pandemic, the ensuing societal disruption limits the time that political leaders are willing to sustain such measures. As soon as each person 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 prone individuals. Handwashing, however, would stay essential to keep individuals from infecting themselves with virus found on the fingers after touching contaminated surfaces.
