FACE VISORS DON'T WORK - obviously

[Browneyesbigbum]

So today a study shows that face visors don't work. You don't say - wasn't it pretty obvious given the minuscule size of virus particles! It's just a virtue signalling - look at us/me aren't we great for saving lives blah blah.....
I mean SD, hand washing naturally but even masks (which I wear to protect others) really isn't going to protect ourselves. The virus particles are very very very small - but it does stop SOME of the aerosols.... but again virtue signalling in the main.

Basically tract and trace and isolate all infected. Isolate after foreign travel too.

YABU - we thoughT visors worked and wear them (hairdressers/shops etc, we still think they work
YANBU - of course they don't work - it's OBVIOUS

'Study co-author, Professor Manhar Dhanak, said: 'From this latest study, we were able to observe that face shields are able to block the initial forward motion of the exhaled jet, however, aerosolised droplets expelled with the jet are able to move around the visor with relative ease.
'Over time, these droplets can disperse over a wide area in both lateral and longitudinal directions, albeit with decreasing droplet concentration.'
Lead author Professor Siddhartha Verma added: 'Face shields have noticeable gaps along the bottom and the sides, and masks with exhalation ports include a one-way valve which restricts airflow when breathing in, but allows free outflow of air.

'The inhaled air gets filtered through the mask material, but exhaled breath passes through the valve unfiltered.'

The research concluded that face shields are not as effective as regular face masks. '

Visor protect the wearer
Masks protect the surrounding people and wearer

I stopped reading at the words 'virtue signalling' Lazy and irritating language. I don't believe most people are 'virtue signalling' . I think most people do their best to make the right choice with the limited information they have at their disposal. Maybe some don't but most do.

YADBU to use the term 'virtue signalling'

I look after vomiting children and do first aid on chikdren who cough straight in my face. I quite like the visor for blocking vomit splashes and full on face coughs.

It just makes people feel safer I guess like a cloth mask. Stops great big gobs of snot shooting out and spraying things but not much else. I agree they do seem pointless without a mask but if you genuinely cant wear a mask it is a face covering.

I wouldnt judge. It's the thought that counts I guess. Please something is better than nothing. How much better? Possibly not a great deal. Doesnt stop me following the rules

A visor is a splash guard only and reduces bodily contents from another coming into contact with eyes, nose and mouth of the visor wearer.

Visors surely can’t provide any protection from air borne particles, but I guess they serve their purpose in terms of protecting the eyes from cough and sneeze splatters.

Does anyone else really hate having answers attached to the voting buttons?

Masks don't really work either, as you say, it's all just virtue signalling.

That's just not true.

So for those who cannot wear a mask... do you suggest we wear a visor, or just go without any form of protection at all?

This "study"; was it a bona fide one? Or have there been arguments for both sides, and the government cherry-picked the one that suits the political agenda?

'The research concluded that face shields are not as effective as regular face masks.' It doesn't say that they don't work at all.

I wear a visor in a classroom as I must have my face visible to be lip read and a mask on corridors. I plan to get a lip reading mask with see through panel as soon as my boss approves it.

DH teaches in a visor, he knows it isn't as good as a mask. He doesn't have the space to keep 2m away from his students, and the kids at the back or dialling in over Teams can't hear him with a mask on. So...he wears the visor as better than nothing.

This information isn't new not sure why you suddenly are posting it.

Visors and masks don't work, have you seen what they wear in bio labs? Not 4 for £2 paper masks, that's for sure

Lost me at virtue signalling.

Just for those who are as stupid as they sound, this has been said from the beginning of the pandemic: masks REDUCE the risks of transmission, they don't ELIMINATE it. Face shields are mostly to protect the eyes.

I just don't know how many times this needs to be repeated.

Given you seem unable to differentiate between risk to the wearer, and risk to other people, YABVU.
I don't believe you understand the topic at all.

I agree about the visors but I don't agree that the track and trace is feasible except when infection levels are very low and community cooperation very high. Not here then.

There was a study done in Switzerland a few weeks ago stating that visors were less effective than masks.
As for masks being indicative of virtue signalling, I suggest a touch of research regarding viral load, op.

Scotland stopped them being used over a month ago. Anyine that wanted to wear one had to use a face mask too.

Masks decrease transmission by a few percent if the wearer has the virus. It won't protect you fully but there will be fewer droplets and they think that the amount of virus you inhale determines how badly you might get it. so that's something. Given most people with the virus are asymptomatic, wearing masks across the whole population will have a small impact on infection - and lots of small changes can add up.

I just wish people would not pull them off their noses or mouths when talking - seen in shops - because it utterly defeats the purpose.

If people feel safer with a visor it’s their choice. Stay at home if you feel unsafe, nothing is 100%

If when people wearing them in bars or restaurants pull them up when walking around or talking then most certainly yes. Otherwise I have always thought they were a bit pointless.

Visor protect the wearer Masks protect the surrounding people and wearer

They sound pretty handy if they protect the wearer.

A few teachers wear them at school, since the children are not wearing masks it could be a good idea

I disagree. I don’t think it’s virtue signalling. It’s just people trying to do the best they can to protect themselves and others. I was grateful that my hairdresser wore a mask AND a visor last week and I wore a mask too.
