The National Health and Nutrition Examination Survey is an on-going, national, comprehensive health survey of the civilian, non-institutionalized US population. A vision assessment was added in 1999 and is on-going. All sample persons aged 12+ years 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 49 years. Data from the vision component in NHANES will 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 measures for a vision objective in Healthy People 2010. Data collection is on-going. The vision interview protocol has been further refined to better assess the frequency of severe visual impairment, particularly as it relates to those who, for various reasons, subsequently do not participate in the vision examination component as conducted in the mobile units. Also effective in 2005, questions on functional vision will be asked during the home interview of all study participants over age 20 years. Vision data, collected since 1999, have not yet been released by the National Center for Health Statistics for analytic purposes. After intensive quality control efforts, a public release of vision data collected over the 1999-2002 time period is projected to occur later in 2004.

全国健康和营养检查调查是一项正在进行的、全国性的、全面的健康调查，对象是美国非收容的平民人口。在一九九九年增加视力评估，目前仍在进行。所有年龄在12岁以上的样本人都接受视力评估，其中测量了远距离戴眼镜者的眼镜处方，测试了有和没有矫正（眼镜/隐形眼镜）的样本人的远距离视力和客观屈光度（还包括对眼睛角膜曲率的评估）。对50岁及以上的人进行近距离视力评估。此外，对年龄在49岁以上的人收集了与视力相关的功能测量的个人访谈数据。NHANES中视力部分的数据将用于估计美国人群中视力损害的患病率，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，并将视力损害与其他健康和疾病措施联系起来。患病率数据将用作2010年健康人愿景目标的基线措施。
