Some experts, however, need more convincing. One concerned citizen conducted a simulation study to determine how particles behave when a person is wearing a face shield.
Engineer Agar’s Simulation Study
Wind Engineer Joshua Agar’s experiment explores the particles’ behavior against a face shield.
In two scenarios, Engr. Agar explained that while shields redirected the flow to the side, they still formed vortices, which means particles have been deposited at the back of the shield. This indicates the face is already involved, and that if a person is not wearing a face mask, there would be a greater chance of contracting the virus.
Engr. Agar also said the situation is worse if the person is facing sideways from the source of the virus.
In a third scenario, the simulation study showed shields could pose an even greater danger in an area where the virus is already present in the air.
Despite the experiment’s potential, Engr. Agar said he wouldn’t be publishing it due to financial constraints. Still, he mentioned he is willing to join other experts in studying the face shield effect.
