Thank you! I had missed this news, so a link to a support article with no explanation was a little mystifying.

I expected this to be for apple factory workers, surprised to see its being sold to other companies.

I believe they are donated to the medical community, not sold.

They aren’t selling them, they are giving them away.

A carpenter friend came up with a similar design a couple of weeks ago. His slides over the visor of a baseball cap. He sourced thin plastic sheets, created a form, then made thousands, and sold them all to an org in B.C., Canada. Great minds think alike.

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 obvio…

Go light a cigarette or incense and and see if a face shield prevents you from inhaling any smoke.

I think a better comparison would be to try inhaling wet steam (i.e. a suspension of liquid H2O) from behind a face shield. You'll probably inhale some, but a lot of it will adhere to the shield.

For what, though? And I'm 100% being honest here, what is the specific situation you are envisioning that requires a face shield in your home? In a medical setting, shields are typically used in conjunction with eye goggles and respirators when performing procedures that have a tendency to cause or be around splashing body fluids. Outside of someone sneezing or spitting on you directly, I can't think of an analogous…

It's the same mentality as people buying guns. What situation that could conceivably arise from a pandemic requires an automatic rifle? It's a generalised sense of "bad things are happening, I need to be prepared for bad things to happen to me".

Rioting, looting, people breaking into your home, police “sick outs.”

See what happens if the electricity goes out or all stores are forced to close.

It is a bit sad that so many people miss or forget these important lessons in HS chemistry :P

Wasn't even told that about those things in HS chemistry in my time in my country, not sure why - considered too dangerous knowledge by educators? Only found out about it on 4chan and gasped on how easily we could have accidentally injured ourselves while cleaning our dorm bathroom.

One has to ponder if starting teching that will result in the next TikTok bleach+vinegar inhalation challenge.

Face shields are to protect against body fluid splatter during invasive bodily procedures and while closely treating patients with explosive coughing fits. Even doctors in hospitals treating Covid-19 patients don't wear them outside those types of circumstances. There is no need for the general public to wear them. It's not like fitting your car with a seat belt, it's like fitting it with an ejector seat.

So your argument is that the risk to the average American is low from COVID? Why do we have 300,000 cases then? Why are 1000 people dying a day? That's already 0.1% of the population, and most of them in the past week!

The risk is very high, my wife is a nurse here in the UK and is infected. Fortunately she has light symptoms and a light cough. When I am with her we both wear a face mask, but there is no need for a shield because I’m not intubating her her or at risk of heavy splatter from close range explosive coughing. Again, even doctors in hospitals only wear face shields under specific circumstances, which are situations the general public are not likely to find themselves in. That’s why you don’t even see doctors and nurses wearing face shields in public or taking them home. Outside those specific circumstances they don’t need them, and we don’t need them.

Viruses don't diffuse through the air like smoke. Viruses are contained within the aerosolised droplets of your bodily fluids that are ejected through sneezing, coughing, blowing the nose. The survival of the virus outside of the body exposed to the elements is limited. Viruses have limited lifespans and can only reproduce within the medium of the bodily fluid. Every virus has different characteristics, and may have a longer or shorter lifespan. These characteristics are more or less universal for viruses though. It's not impossible for them to travel longer distances through the air. For the most part they are limited to the initial propulsion from the body. A better analogy would be spraying an aerosol can and watching how the droplets settle.

> There is currently a global pandemic afoot that is spread by droplets expelled from people's mouth and nose. Do you have any source on how face shields are an effective tool against atomized covid19 viruses? The general guidance is that facial masks are effective at barring infected people from emitting contaminated particles, but not good at stopping healthy people from having contact with the virus. Therefore why…

I hear mask promoters say the “it’s to protect others from you” line, only to turn around and say “masks are obviously useful, that’s why doctors wear them.” The truth is, mask use is built on incredibly shaky evidence, so it’s no surprise that now face shields will become part of the hype. Both may indeed be useful, but without a clear model of effectiveness, it’s hard to make good assessments.

Also, tin foil hats. You can't prove they DON'T work, can you? Even if they only add marginal protection, every bit counts. And they might, so can it hurt? This is why we are recommending tin foil hats to all Americans. That and a nice contribution from the tin foil lobby. We expect all Americans to commence procuring and constructing tin foil hats, and arguing about it on social media, and hope that this distracts them from noticing that their government is practically a failed state.

It turns out that "feeling safe" isn't the same thing as being safe, and feelings of safety will not actually effect infection rates, but Americans can't quite grasp that. And, hey, feelings of safety are about all we've got now, so.
