The National Health and Nutrition Examination Survey is an on-going, national, comprehensive health survey of the civilian, non-institutionalized US population. A vision component was added in 1999 and is on-going. All sample persons aged 12+ years presenting to the Mobile Examination Center undergo a vision assessment in which measures of the eyeglass prescription in people who wear glasses for distance, tests the distance visual acuity of sample persons with and without correction (glasses/contacts) and an objective refraction (incorporating also an evaluation of the corneal curvature of the eye) are obtained. A visual acuity at near is assessed in persons age 50 years and over. In addition, personal interview data on functional measures related to vision are collected on people over the age of 19 years (prior to 2005, these data were collected only from those 50 years of age and older). Data from the vision component in NHANES can be used to estimate the prevalence of visual impairment in the U.S. population, describe the distribution of refractive error in the U.S. population, evaluate the impact of vision loss on functional abilities, and relate visual impairment to other health and disease measures. The prevalence data will be used as baseline and follow-up measures for a vision objective in Healthy People 2010. Data collection is on-going. NEI intramural staff worked closely with NHANES staff on data cleaning and documentation before public release. Vision data, collected between 1999 and 2002, were publicly released by the National Center for Health Statistics for analytic purposes in spring 2005. Data collected in 2003 and 2004 were released to the public in spring 2006. Interested users of these data can download them from the NHANES website http://www.cdc.gov/nchs/nhanes.htm.

国家健康和营养检查调查是一项持续的，全国性的，全面的健康调查的平民，非制度化的美国人口。1999年增加了一个远景部分，目前仍在继续。所有12岁以上的样本人到移动的检查中心进行视力评估，其中测量戴眼镜的人的远距离视力，测试样本人在有和没有矫正（眼镜/接触）的情况下的远视力敏锐度，并获得客观屈光（还包括眼睛的角膜曲率的评估）。对50岁及以上的人进行近视力评估。此外，还收集了19岁以上人群的视力相关功能测量的个人访谈数据（在2005年之前，这些数据仅收集自50岁及以上人群）。 NHANES中视力部分的数据可用于估计美国人群中视力障碍的患病率，描述美国人群中屈光不正的分布，评估视力丧失对功能能力的影响，并将视力障碍与其他健康和疾病措施联系起来。患病率数据将被用作基线和后续措施的视力目标在健康的人2010年。 数据收集正在进行中。 NEI内部工作人员与NHANES工作人员密切合作，在公开发布之前进行数据清理和记录。1999年至2002年收集的视力数据于2005年春季由国家卫生统计中心公开发布，用于分析目的。2003年和2004年收集的数据已于2006年春季向公众公布。对这些数据感兴趣的用户可以从NHANES网站http://www.cdc.gov/nchs/nhanes.htm下载。
