If you want to avoid the usual eyesight problems as you get older - such as macular degeneration and cataracts - start running. Apparently it will keep your eyes as fit as your body.
New research suggests that vigorous exercise, such as from running, can help keep eyes in good health right into old age. After reviewing the health profiles of 41,000 runners for seven years, the researchers discovered that the exercise dramatically reduces the risk of vision problems later on.
Men who ran more than 5.7 miles a day had a 35 per cent lower risk of developing cataracts compared with those who ran less than 1.4 miles a day. It's also good for warding off age-related macular degeneration. Men and women who ran more than 2.4 miles a day had up to a 54 per cent lower risk of developing the problem.
