I get that some people can’t wear masks for medical or psychological reasons, but surely the vast majority of those could wear a visor instead?
If someone is physically unable to attach a mask/visor, I’m thinking they would need to have a carer with them anyway who could support that.
This leaves those with severe autism, where I recognise there may need to be an exception.
If this is the case, wouldn’t it be reasonable to insist on everyone wearing a face covering in public indoor places, with a much smaller set defined exemptions supported by a medical note.
Or am I missing something?
