Pandemic Has Increased Nearsightedness in Kids, Study Shows

(from NBC) The rate of nearsightedness in children more than doubled during the pandemic, according to researchers who analyzed eye test data from nearly 2,000 Hong Kong school-age children. “Our study showed that less time spent outdoors and more time spent on near work, including screen time, is associated with faster progression in short-sightedness, or myopia," said the lead scientist. Animal studies have suggested that outdoor light helps protect against myopia by sparking “an increase in dopamine release in the retina, which inhibits elongation of the eyeball." Experts recommend two hours of outdoor time or more each day for children.
