Three approaches in particular were found to make a difference, AOA notes:

  • Physical distancing. Transmission was reduced with distancing of 1 meter or more, and greater distance led to more protection.
  • Face masks. Their use “could result in a large reduction in risk of infection with stronger associations with N95 or similar respirators compared with disposable surgical masks or similar,” AOA reports.
  • Eye protection. Equipment such as such as goggles and face shields was linked to less infection.

The researchers, including several from McMaster University in Ontario, published their findings online this month in The Lancet.

The findings are in line with Centers for Disease Control and Prevention and AOA recommendations,, said Andrew Morgenstern, OD, director of AOA’s Clinical Resources Group.
