目的.提供尼日利亚成年人屈光不正的患病率和类型、配戴屈光矫正镜的比率以及现有屈光矫正镜可满足远距离矫正需求的程度的数据。采用多阶段、分层、整群随机抽样方法，以与规模成比例的概率确定了15 027名年龄≥ 40岁的人的全国代表性样本。使用简化的logMAR tumbling-E视力表测量远视力。所有参与者均接受了自动验光，并对视力≥ 40岁的参与者进行了计数。未矫正的屈光不正导致77.9%的轻度视力损害（
PURPOSE. To provide data on prevalence and types of refractive error and the spectacle-wearing rate among adults in Nigeria and the degree to which the need for distance correction could be met by off-the-shelf spectacles.METHODS. Multistage, stratified, cluster random sampling with probability proportional to size was used to identify a nationally representative sample of 15,027 persons aged >= 40 years. Distance vision was measured using a reduced logMAR tumbling-E chart. All participants underwent autorefraction, and those with presenting acuity of = 40 years who were enumerated. Uncorrected refractive error was responsible for 77.9% of mild visual impairment (
