Study says nearsightedness on the rise

For both kids and adults in the U.S., nearsightedness is increasing.

A new survey comparing eyesight information for 4,400 people tested in 1971-1972 and 8,300 people tested from 1999-2004 found that instances of myopia has increased by 66 percent in the last three decades. What’s more, the severity of nearsightedness has increased, too, with moderate and severe cases both more than doubling.

What’s changed? While nearsightedness isn’t completely understood, many point to the increased amount of time now spent in front of TV and computer screens, which may strain the eyes. Another factor, specifically for children, is marked decrease in the amount of time spent outside. According to vision experts, more exposure to outdoor light allows the eye to see farther and focus better. Additionally, the lack of time in the sun can translate to lower levels of vitamin D, which is known to regulate eye growth (nearsighted eyes are usually longer than eyes that can see 20/20).

What does this mean for the long-term? Researchers aren’t sure. At the very least, it sounds like another great reason to limit your kid’s screen time and encourage outdoor play.
