So those stupid face visors that loads of workers in shops like Waitrose and Boots are wearing have now been shown to be useless. That much has been obvious all along given the enormous gaps around them but nice to see some sort of study into them.
Anyway the new restrictions are quite clear that all retail staff have to wear face coverings from tomorrow, I'm not sure why they were ever allowed not to, it made no sense that shoppers had to wear them but shop workers were magically immune.
Plastic face shields DON'T work
Lead researcher Lakoto Tsubokura, from the Riken Centre in Japan, said he would not recommend wearing face shields in the place of face masks. His simulations revealed they offer limited protection.
