Using Face Coverings: Face Visors, Shields and Transparent Face Coverings
A face visor or shield only offers only limited protection compared to a face covering. This is so, since they do not sufficiently cover the nose and mouth, and do not filter airborne particles. It is wise to, thus, consider the best and premium face coverings.
Transparent face coverings can assist in communicating for those that need facial expressions. However, their effectiveness is not reinforced by evidence. To be most effective, a face covering must effectively secure on the face to cover the nose and mouth. It must be made of a breathable material that is easily capable of filtering airborne particles.
