The virus laughs at these masks. It won't stop any virus. It only helps for people who are already sick and sprinkling cough droplets full of virus to others, but it does nothing for protecting the wearer from infection.
Exactly. Those are pitchers masks, not catchers masks. On the receiving end you want a resporator and goggles which both seal to the face.
I don't see where the article claims that wearing one will protect against infection. It does say that they can help prevent the spread of infection, which is accurate.
