Nonmetro and metro elderly people are contrasted in their risk of having (relative to lacking) an impairment in distance vision and in near vision.
Using the 1995-1996 panel (Wave 2) of the Asset and Health Dynamics Among the Oldest Old (AHEAD) Survey, the prevalence of 5 eye-threatening conditions (cardiovascular disease, cataract, diabetes, glaucoma, and hypertension), a variety of medical treatments for these conditions, the number of talks/visits with doctors in the 2 years before Wave 2, and several relevant demographic characteristics of the 6,817 respondents were controlled.
Nonmetro and metro elders have the same risk of impairment in distance vision. After controlling for other factors, nonmetro elders have a higher risk than their metro peers of an uncorrected impairment in near vision (probably presbyopia).
Nonmetro elders may confront more impediments to updating their corrective lenses for presbyopia. Implications for public health policy are discussed.
对比非都市和都市老年人出现远视力和近视力障碍（相对于无视力障碍）的风险。
利用“最年长老人资产与健康动态调查（AHEAD）”1995 - 1996年面板数据（第2波），控制了5种威胁视力的疾病（心血管疾病、白内障、糖尿病、青光眼和高血压）的患病率、针对这些疾病的各种医疗治疗、第2波之前2年与医生交谈/就诊的次数，以及6817名受访者的若干相关人口统计学特征。
非都市和都市老年人出现远视力障碍的风险相同。在控制其他因素后，非都市老年人出现未矫正近视力障碍（可能是老花眼）的风险高于都市同龄人。
非都市老年人在更新老花眼矫正镜片方面可能面临更多障碍。讨论了对公共卫生政策的影响。
