What is a Face Visor?

A face visor, also known as a face shield, is an item of personal protection equipment (PPE) that aims to shield the wearer from hazardous flying objects. During the Covid-19 pandemic, people wear face visors as a method to prevent airborn respiration droplets from touching their face. Specifically, droplets that could occur from sneezing or coughing can be blocked by wearing a face visor.

What is a Face Shield?

Face visors, also called "face shields", consist of a band with a plastic shield which is placed on a person's head to cover their face. Its purpose is to prevent floating particles that may contain covid-19 or other diseases from landing on your face.

They are considered as possibly the next step in fighting covid-19. Some advantages are they are easy to wear and are good at blocking droplets which can contain viruses. These droplets come from respiration, where someone who may be infected breathes out small water vapour into the air. Face shields can help block these droplets from landing on your face.

Why Wear a Face Visor?

Face visors can be worn by people who are required to greet many people constantly during the day, in situations where people may be infected with Covid-19. It is suitable to cashiers, store greeters, traffic cops, bus drivers and many other individuals whose job primarily has them speaking to hundreds of people every day. They are also used by hospitals where people are being treated for Covid-19 infection.

What Role Do Face Visors Provide Against Covid-19?

Covid-19 is primarily spread through respiration droplets. A white paper discussing the efficacy of face shields discussed the role of face shields, or face visors, in preventing the spread of Coronavirus. A coughing simulator showed that a face visor reduced inhalational exposure.

During testing of an influenza-laden cough aerosol with a volume median diameter (VMD) of 8.5 μm, wearing a face shield reduced the inhalational exposure of the worker by 96% in the period immediately after a cough.

In addition to covering your nose and mouth, face shields also protect the eyes. Covid-19 infected respiration droplets could potentially enter the eyes and cause infection. Face visors reduce the risk of this happening.

Other Hazards Protected By Face Shields

Face visors can also contibute protection from flying object hazards, chemical splashes and potentially infectous materials. They can shield the eyes from respiration droplets which could contain not only Covid-19 but influenza, H1N1 virus and other types of infections. They can also be used with glasses, goggles and face masks for increased protection.
