University offers frontline medics solution to keep goggles fog-free
SHENZHEN, Feb. 19 (Xinhua) -- Many of the medical staff on the front line of the battle against the novel coronavirus are facing a problem -- foggy goggles. They work for hours every day wearing medical goggles, but cannot get rid of the fog that blurs their vision.
Researchers from the Southern University of Science and Technology based in Shenzhen, south China's Guangdong Province, have developed anti-fog wipes that will help make foggy goggles a thing of the past.
The wipes contain a new nanomaterial. After wiping the inside of the goggles' surface, a transparent protective coating will be formed within seconds to stop the buildup of condensation.
Also, the wipes include a 75 percent alcohol-based solvent component, which is effective against viruses.
Sun Dazhi, lead researcher and an associate professor from the university's Department of Materials Science and Engineering, said the use of the wipes, non-toxic to human eyes, will ensure the lens of a pair of goggles remains fog-free for at least 24 hours.
The research team has donated 6,000 of the anti-fog wipes to the Third People's Hospital of Shenzhen, a designated hospital for the epidemic.
Key medical supplies, including masks and goggles, are still in high demand as the epidemic continues in China. A number of enterprises nationwide are stepping up efforts on production to ease the shortage.
