If someone is facing me and a stream of airborne particles hits a plastic shield instead of streaming out to me, it seems pretty likely that I will be protected.
I'm certainly open to the idea that fluid mechanics are complicated and somehow air currents are going to do unhelpful things, but until I find someone with a paper on the topic I'd much rather be talking to someone wearing a face shield than not.
Plus obviously wearing a face shield will protect against self-inflicted infections from a contaminated finger.
