In December, the government’s task force on pandemic response required people to wear face shields on top of face masks outside their homes.
The effectiveness of wearing face shields in preventing COVID-19 transmission has become a subject of debates.
The US Centers for Disease Control and Prevention is not recommending face shields as a substitute for masks, saying these are not as effective at protecting people from respiratory droplets. Face shields also have large gaps below and alongside the face.
A study published in the journal Physics of Fluids does not find face shields helpful in deflecting droplets.
But the Department of Health has insisted that wearing face shield together with a mask, and following physical distancing rules could decrease risk by more than 90%.
The Philippines, which has one of the worst outbreaks in Southeast Asia, has so far reported 1.2 million coronavirus infections, including over 21,000 deaths.
