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 rapid movement of individuals throughout the globe, has set the stage for an outbreak of proportions not seen in the last century.

For infection with this virus to occur, it should come into contact with the eyes, nose, or mouth. This occurs when droplets produced by an infected person (via talking, coughing or sneezing), land on the face of one other person. These infectious droplets can travel up to 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, nose or mouth, is another way for an infection to occur. Subsequently, 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 stop publicity to infectious droplets. Nonetheless, face mask shortages are occurring because of interruptions within 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 and protect themselves while providing care. Even when plentiful, face masks are usually not without problems. As soon as they develop into wet from the humidity in exhaled air, they lose effectiveness. In addition, some individuals contact their face more often to adjust the mask, which will increase the risk of an infection if the palms 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 greater solution. There are numerous types, however all use clear plastic material attached to a headpiece to cover the eyes, nose and mouth, thereby stopping 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 supply chains of a number of industries, the present supply is less restricted than for face masks. They'll even be made at dwelling with gadgets from office supply and craft stores.

Every health care worker needs a face shield for protection at work. While face masks are still needed in some situations, implementation of face shields will drastically reduce the need for face masks and lengthen the restricted national supply of masks. Engineers have produced designs for face shields which might be in the public domain, and fabrication at scale is relatively simple. To make sure that every health care worker has a face shield, production will need to ramp as much as meet the demand through current manufacturers and recruitment of additional factories. Because the design is straightforward, huge rapid production wouldn't be difficult.

Once the health care workforce is equipped, distribution to the public ought to begin, with a goal to provide a face shield to each individual in the country. It needs to be worn anytime an individual leaves their residence, while in any public place, and even at work. Though shelter-at-home approaches are needed to "bend the curve" of this pandemic, the ensuing societal disruption limits the time that political leaders are keen to sustain such measures. As soon as each person is shielded, nonetheless, reducing restrictions on movement would carry less risk. Universal shielding might reduce reliance on social distancing since infectious droplets cannot reach the face of inclined individuals. Handwashing, nonetheless, would stay essential to maintain individuals from infecting themselves with virus found on the hands after touching contaminated surfaces.
