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

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

For infection with this virus to happen, it must come into contact with the eyes, nostril, or mouth. This occurs when droplets produced by an infected individual (via talking, coughing or sneezing), land on the face of one other person. These infectious droplets can journey 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 one other way for an 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 publicity to infectious droplets. However, 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 compelled to resort to scarves and bandannas in a last-ditch try and protect themselves while providing care. Even when plentiful, face masks are not with out problems. As soon as they grow to be wet from the humidity in exhaled air, they lose effectiveness. In addition, some individuals contact their face more often to adjust the mask, which increases the risk of infection if the fingers are contaminated.

Cloth 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 various types, but all use clear plastic material connected to a headpiece to cover the eyes, nostril 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 stop the wearer from touching their face. Importantly, face shields are durable, might 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 supply chains of multiple industries, the current supply is less limited than for face masks. They'll even be made at home with gadgets from office supply and craft stores.

Every health care worker wants a face shield for protection at work. While face masks are still wanted in some situations, implementation of face shields will enormously reduce the necessity for face masks and prolong the limited national supply of masks. Engineers have produced designs for face shields which might be in the public domain, and fabrication at scale is comparatively simple. To ensure that every health care worker has a face shield, production might want to ramp up to meet the demand by way of current manufacturers and recruitment of additional factories. Because the design is easy, large fast production would not be difficult.

Once the health care workforce is equipped, distribution to the public should start, with a goal to provide a face shield to each person within the country. It ought to be worn anytime a person leaves their house, while in any public place, and even at work. Though shelter-at-house approaches are wanted to "bend the curve" of this pandemic, the ensuing societal disruption limits the time that political leaders are prepared to maintain such measures. As soon as every particular person is shielded, however, reducing restrictions on movement would carry less risk. Universal shielding could reduce reliance on social distancing since infectious droplets can't attain the face of vulnerable individuals. Handwashing, nonetheless, would stay essential to maintain folks from infecting themselves with virus discovered on the fingers after touching contaminated surfaces.
