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. But, if you do have an eye disease, the sooner it is found, the more likely it is that treatment can help preserve your vision."
The study authors made the following recommendations:
Percent of people with visual impairment
that CAN be corrected with glasses/contact lenses
12-19 years 93.1%
20-39 years 90.0%
40-59 years 92.4%
60+ years 59.5%
Below poverty level 84.1%
At or near poverty level 80.1%
Over (two times) poverty level 88.7%
Mary Frances Cotch, Ph.D., chief of the NEI's epidemiology branch and one of the study authors, concluded, "Providing corrective lenses to people who need them is an important public health issue with implications for safety and quality of life."
The National Eye Institute (NEI) is part of the National Institutes of Health (NIH) and is the Federal government's lead agency for vision research that leads to sight-saving treatments and plays a key role in reducing visual impairment and blindness.

The National Institutes of Health (NIH) "The Nation's Medical Research Agency" includes 27 Institutes and Centers and is a component of the U. S. Department of Health and Human Services. It is the primary federal agency for conducting and supporting basic, clinical, and translational medical research, and it investigates the causes, treatments, and cures for both common and rare diseases.
