I noticed that many people wear these visors instead of masks, often at an angle such that it barely comes level with their chin, and wonder how on earth that's providing any protection for the wearer or whoever they are projectile-breathing at. Can you explain?

As with any form of protection, it needs to be approprately fitted and depends on the person using it properly.

Nothing is certain with CV19 and opinions vary considerably, but after Googling for a bit, the consensus seems to be: a visor appears to provide more protection for the user, than a mask, but isn't as effective at preventing the user spreading the virus. It helps to protect the wearer's eyes from virus-laden droplets and should also reduce spread to some degree by reducing the momentum of a cough or sneeze, but the bottom is still open, so some of it will fall onto objects below.

Ideally people should wear both a visor and a mask, but if someone can't wear the mask, then they should wear a visor. I would think a long visor, extending well below the chin and a scarf around the neck, to fill the gap, even if it doesn't cover the face, would also provide more protection to others, by stopping droplets from falling on surfaces below.

I think my motorcycle helmet will protect me more than a mask and should also do a decent job of preventing me spread it, as it's well-fitted and there's some fabrick under the chin. Lots of this seems to be common sense.

It all depends how you keep your hands away from these barriers.

A visor should do a better job of preventing someone from touching their face, than a mask, which will harbour the virus, when it becomes damp.

I'm not sure if that makes that much difference though. It's true, people touching their mouthes and noses helps spred the virus and was originally believed to be the main mode of transmission, but now droplets suspended in the air is thought to be more likely.

You touch the outside of the visor to lift it up. The first thing you do is rub yer nose. Bingo.

Shops have tended to deny those wearing them entry, for security reasons, but a helmet, with screen and visor, will provide good protection both against spreading and contracting COVID-19, so should be acceptable.

We already have mask laws here and the couple of times I've been places I haven't taken my helmet(with chin curtain installed) off and I haven't had any problems. Nobody says anything. However, when I took a walk with my kids without a mask(it was an impromptu walk when we were already playing outside our home) I walked by the police station and parked police cars with police inside and nobody said anything then either. I guess it depends on how strongly enforced it all is. If they go full authoritarian you'll probably need a mask with your head isolated in a helmet.

Floating aerosols aren't even a little bit like shit thrown off a grinder or whatever. Would a visor be OK to stop your lungs filling with sawdust? Of course not.

That was my initial thought, and why medical professionals wear them, and why they are a useful additions to masks. But my puzzlement is where they are used on their own - airflow is just going to go around the sides.

Would it protect you from sawdust in a workshop? Briefly, I would suggest.

Rather than fantasy: When you pass by a lady and sense her perfume, you know she may have infected you. That is the meaning of "aerosol". Now you have a simple test for whatever you want to use.
Glasses are useful for checking how air-proof the mask is around the nose. The masks my wife made have a strong metal wire to keep the gaps closed that tend to form on both sides of the nose. That was my contribution..
