In recent weeks there has been increased discussion around the potential use of face shields as a tool to help exit lockdown and prevent further spikes in infections of Covid-19.



Face shields are plastic face visors that provide full face protection. This type of face covering can play an important role in tackling the virus. Face shields provide a high level of protection for the wearer. Given they cover the whole face – the mouth, nose and eyes – a high percentage of viral particles are prevented from reaching the wearer. Face shields are arguably best at protecting from coughs and sneezes.

 

 

 

According to a recent study Dr. Rajat Trehan based in Janakpuri, Delhi has shared a clinically accurate view on the usage of Masks and Face shields. According to Mr. Trehan, People release respiratory fluids during exhalation in the form of droplets across a spectrum of sizes.1-9 These droplets carry virus and transmit infection. Covid19 has now mutated and has shown more variants. Using Face shield over masks will help in decreasing the chances of catching the virus.

 

 

 

The US CDC has acknowledged that SARS-CoV-2, the coronavirus that has caused the Covid-19 pandemic, is airborne. Dr. Trehan says “A person can be infected when aerosols or droplets containing the virus are inhaled or come directly into contact with the eyes, nose, or mouth. Use of face shield should be made mandatory like the use of masks is mandatory as Double masking lessen down infection chances and cut severity rates by as much as 85% and with face shields we can reach upto 95%.”

 

 

 

Shields, meanwhile, have been found to successfully block droplets. In addition, face masks are not meant to protect the wearer -- they leave other vulnerable parts of the face exposed, like the eyes. They are meant to keep an asymptomatic or pre-symptomatic person from spreading it to others.

 

 

 

As opposed to face masks, face shields actually completely cover the face from the head extending all the way below the chin. As a result, it prevents you from touching your own face which isn’t exactly possible with just face masks.

 

 

 

In the study, it was found that face shield reduced the inhalational exposure of the worker by 96 per cent within 18 inches of a cough. They can also prove to be far more comfortable and convenient to be worn by people when compared to face masks which may be restrictive and uncomfortable when used for very long hours.

 

 

 

Corona is aggressively spreading around the world. People are using masks, PPE, kits, etc. to avoid the coronavirus infection. Knowing the correct way to use face masks and shields is very important.

 

 

Another key advantage of wearing a face shield is that a face shield can be sterilized and cleaned. It can be used until it breaks or cracks. Face Shield can also be cleared by cleaning it with alcohol-based sanitizers or by washing it with soap to make it infection-free.
