Access to refractive care is examined by comparing uncorrected and corrected (with eyeglasses or contact lenses) distance visual acuity across eight race-sex-economic status groups. Of those with less than 20/20 uncorrected distance visual acuity, the age-adjusted proportion using corrective lenses is examined across these sociodemographic groups to assess unmet need in vision care. Measurements of distance visual acuity were obtained for 2,828 adults aged 25-74 years from the national probability sample selected for the 1974-1975 National Health and Nutrition Examination Augmentation Survey. Questionnaire responses were collected on usual correction. Individuals were classified by race, sex, and economic status. Weighted least squares categoric data analysis showed that blacks, males, and nonpoor persons have a higher proportion with 20/20 uncorrected distance vision than whites, females, and poor persons. Individuals who are white, male, and nonpoor are more likely to have 20/20 corrected distance vision than their counterparts.
通过比较八个种族-性别-经济状况组中未矫正和矫正（使用眼镜或隐形眼镜）后的远距离视力，来研究获得屈光不正治疗的情况。在未矫正远距离视力低于20/20的人群中，对这些社会人口统计学组中使用矫正镜片的年龄调整比例进行研究，以评估视力保健方面未满足的需求。从为1974 - 1975年国家健康与营养检查补充调查选取的全国概率样本中，获取了2828名年龄在25 - 74岁的成年人的远距离视力测量数据。收集了关于通常矫正情况的问卷回复。个体按种族、性别和经济状况进行分类。加权最小二乘分类数据分析表明，黑人、男性和非贫困人口中未矫正远距离视力为20/20的比例高于白人、女性和贫困人口。白人、男性和非贫困人口比其他人群更有可能矫正后远距离视力达到20/20。
