Study finds most Americans have good vision, but 14 million are visuall...( A National Institutes of Health (NIH) s...),Health

A National Institutes of Health (NIH) study has found that although 94 percent of Americans aged 12 and older have good vision, the remaining six percent, or 14 million, are visually impaired. Of these, more than 11 million have uncorrected visual impairment, such as nearsightedness. They need eyeglasses or contact lenses to improve their vision. Teenagers, people with diabetes, Hispanics, and people who are economically disadvantaged have higher rates of visual impairment and can most benefit from corrective lenses. This study is published in the May 10, 2006 issue of the Journal of the American Medical Association.

Elias A. Zerhouni, M.D., director of the NIH, said, "This is the first national survey on vision since the mid-1970s, and it confirms that uncorrected visual impairment is a major public health problem. The good news is that we now have information on the extent of visual impairment in the United States that will be available to policymakers as they seek to address health care issues at the local, state, and national levels."

This study, designed and supported by the National Eye Institute (NEI) of the NIH, was part of the National Health and Nutrition Examination Survey, an ongoing survey conducted by the National Center for Health Statistics of the Centers for Disease Control and Prevention. More than 15,000 people participated in the survey from 1999 to 2002. They were interviewed in their homes and were invited to undergo a comprehensive health examination in a mobile examination center (MEC). More than 14,000 reported to a MEC, and more than 13,000 completed visual acuity tests.

Paul A. Sieving, M.D., Ph.D., director of vision research at NIH, said, "This study found that most people who have a visual impairment could achieve good vision with proper eyeglasses or contact lenses. So, if you have trouble seeing, you should get your eyes examined as soon as possible. It may be that corrective lenses will improve your vision. B
