TIMELY NEWS: Too much sunshine can be bad for your eyes, yet not enough might make you more nearsighted. How’s that for a health and well-being Catch 22?
New studies show that people who spent a significant amount of time outside as a kid enjoy better eyesight as an adult. It has something to do with greater exposure to sunlight during childhood, although researchers haven’t figured out exactly how it all works.
Nearsightedness (myopia) is a condition in which close objects appear clear but distant objects are blurry. It affects about 40 percent of Americans and as many as 90 percent of young adults in Asian countries. A 2015 study estimated up to one-third of the world's population may be nearsighted by the end of the decade - that's 2.5 billion people. At that rate, experts predict that nearly half the world will be nearsighted by the year 2050.
“The big question is, what’s causing this?” asks Sandy T. Feldman MD, one of the nation’s top eye surgeons. “Turns out, it’s not that we’re spending too much time on our computers and phones. It’s that we’re spending too much time indoors.”
WHY IT’S A BIG DEAL: Two studies from 2007 and 2008 found that rates of nearsightedness in children appeared to be closely linked to the amount of time spent outdoors. A more recent study gave vision exams to 3,100 older European men and women and took detailed histories of their education, careers and how much time they spent outside throughout their lives. This information was cross-referenced with historical data about sunlight. The results? An undeniable correlation between current eyesight and a person’s lifetime exposure to sunlight.
“There are still a lot of unanswered questions, but it’s clear is that the more time children spend outdoors, the lower their risk of nearsightedness,” advises Dr. Feldman. “Just don’t overdo it. Be sure to take precautions, like wearing sunscreen and sunglasses and wide-brimmed hats. Also, ty to avoid going out at mid-day, when damaging UV rays are strongest.”
