Researchers from the universities of Bristol and Cardiff have found that children who spend more time outdoors playing when they are aged between eight and nine are approximately half as likely to become short-sighted by the time they are 15.The symptoms of short-sightedness, also known as myopia, often start around puberty. Things in the distance appeared blurred. Glasses, contact lenses or other treatment such as laser surgery (later in life) may be needed to improve vision.To see more details visit,www.webmd.boots.com
