Japan's supercomputer says face shields are ineffective

Sep 23, 2020 18:24 IST

Plastic face shields are ineffective when it comes to trapping respiratory aerosol droplets, Japan's supercomputer has found. A simulation done by Fugaku, world’s fastest supercomputer has cast a doubt on the effectiveness of face shields for protection against coronavirus, as almost 100% of airborne droplets of less than 5mm in size escaped through the plastic visors used to make them. To this end, Riken a research institute near Osaka, has also discovered that 'about half of larger droplets measuring 50 micrometres found their way into the air' from such shields.
