Another in a line of studies on sunlight and myopia (near-sightedness) demonstrates that people who spend more time is the sun are less likely to have this pandemic vision problem. Other research on the relationship of sunlight exposure and myopia, some of it reported in my book, primarily considered the risk of myopia in children. This new investigation, however, surveyed young adults, and found that those who had the lowest exposure to sunlight were twice as likely to contract myopia.
Myopia is not an insignificant problem; when severe, it may lead to blindness. Obviously, we need to make sure that our eyes receive some sunlight regularly to help prevent this widespread disorder.
