How Face Shields Keep Viruses from Spreading

John M. Fife holds an undergraduate degree in computer science and statistics from Brigham Young University in Provo, Utah. Apart from working as the chairman of United American Healthcare Corp in Chicago, John M. Fife serves as the president of Typenex Medical, LLC. Typenex sells personal protective equipment that includes face masks, eye-protection, disposable gowns, and face shields.

A face shield reduces the amount of exposure to a virus projected from as little as 18 inches away by as much as 96 percent.

When it comes to stopping the transmission of an infection, a face shield provides eye protection. Another way infection transmission is prevented is by wearing a shield that prevents touching the eyes and face.

A face shield offers more than just eye protection. Shields are often more convenient to use, so they don’t hinder the wearer’s breathing. Compared to cloth masks, which are less durable and need to be machine or hand washed, face shields are often much simpler to keep clean and reuse.

It’s also much easier to speak when using a shield, as it lies in front of the face. Face shields are also transparent, allowing hearing-impaired people to read the lips of someone else wearing a protective face shield.
