You know what’s not fun? Wearing a face mask to help slow the spread of COVID-19 like a responsible citizen, and then getting fogged-up glasses. Yes, we’d rather get foggy glasses than catch or spread this unprecedented virus—or go against CDC recommendations to wear a face covering in public.
Back in 2011, two scientists published a study in the Annals of The Royal College of Surgeons of England that illuminates a simple, at-home hack for this very phenomenon, which “can be a nuisance and even incapacitate” medical staff. Anti-fogging spray products do exist, but this trick requires zero shopping and adds no risk of putting harsh chemicals near the sensitive eye area.
