Smartphones, Summer Birth Could Raise Kids’ Odds for Nearsightedness

“Managing your child’s device screen time and increasing their outdoor play can help reduce the risk of developing myopia,” Wong said. “We must better monitor our children’s device activities, even during their preschool years.”

Surprisingly, the researchers said children born as a result of fertility treatment had a 25 percent to 30 percent lower risk for myopia. They said that may be because many are born premature and have developmental delays, which could account for shorter eye length and less myopia.
