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. '
