重要性 需要对低视力和失明的患病率和发病率进行最新估计，以便为政策制定者提供信息并制定计划，以满足未来对低视力康复服务的需求。 目的 提供对美国低视力和失明的发病率和患病率的最新估计。 设计、环境和参与者 根据 2007-2008 年国家健康和营养检查调查，视敏度测量作为年龄的函数，其中包括种族和 种族群体，用于估计视力障碍的患病率和发生率。获得了 6016 名调查参与者的数据，年龄范围从 18 岁以下到 45 岁以上，以估计不同年龄组的患病率。低视力的发生率和患病率（视力较好的眼睛的最佳矫正视力 [BCVA]
IMPORTANCE Updated estimates of the prevalence and incidence rates of low vision and blindness are needed to inform policy makers and develop plans to meet the future demands for low vision rehabilitation services.OBJECTIVE To provide updated estimates of the incidence and prevalence of low vision and blindness in the United States.DESIGN, SETTING, AND PARTICIPANTS Visual acuity measurements as a function of age from the 2007-2008 National Health and Nutrition Examination Survey, with representation of racial and ethnic groups, were used to estimate the prevalence and incidence of visual impairments. Data from 6016 survey participants, ranging in age from younger than 18 years to older than 45 years, were obtained to estimate prevalence rates for different age groups. Incidence and prevalence rates of low vision (best-corrected visual acuity [BCVA] in the better-seeing eye of
