I agree that face shields are inadequate. Good luck in the laboratory.

This is also going to be an issue for poll workers, that's two months away, but preparations are beginning for that.

I will not admit to being a packrat, but I have ~100 acetate transparencies and I saw a vid of using one, with a hole punch to slip your eyeglass temples through, to make a cheap face shield if needed. If someone is standing with a line of 100s ppl coming by, some sort of mask to filter incoming air and a face shield to deflect the buggars is prudent.
