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 speedy movement of individuals across the globe, has set the stage for an outbreak of proparts not seen within the final century.

For an infection with this virus to happen, it must come into contact with the eyes, nostril, or mouth. This happens when droplets produced by an contaminated person (via speaking, coughing or sneezing), land on the face of another person. These infectious droplets can journey as much as 6 feet, which is the reason to promote social distancing. Touching a surface that is contaminated with infectious droplets and then touching one’s own eyes, nostril or mouth, is one other way for infection to occur. Due to this fact, the important thing to avoiding 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. Nevertheless, face mask shortages are occurring because of interruptions in the provide 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 not without problems. As soon as they become 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 hands are contaminated.

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

We believe 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, nose 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, will be cleaned after use, reused repeatedly, and for many individuals are more comfortable than face masks. Because these shields are reusable and are diversified across the supply chains of a number of industries, the current supply is less restricted than for face masks. They will even be made at residence with items from office provide 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 drastically reduce the necessity for face masks and extend the restricted national supply of masks. Engineers have produced designs for face shields which are in the public domain, and fabrication at scale is relatively simple. To ensure that each health care worker has a face shield, production will need to ramp as much as meet the demand via present manufacturers and recruitment of additional factories. Because the design is simple, huge fast production wouldn't be difficult.

Once the health care workdrive is supplied, distribution to the public should begin, with a goal to provide a face shield to each particular person in the country. It needs to be worn anytime a person leaves their house, while in any public place, and even at work. Though shelter-at-dwelling 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 every particular person is shielded, however, reducing restrictions on movement would carry less risk. Common shielding may reduce reliance on social distancing since infectious droplets can not reach the face of susceptible individuals. Handwashing, nevertheless, would remain essential to maintain individuals from infecting themselves with virus discovered on the hands after touching contaminated surfaces.
