INTRODUCTION
Presbyopia, the leading cause of vision impairment globally, is common during working years. However, no trials have assessed presbyopia's impact on income.
METHODS
In April 2017, we conducted a census among 59 Bangladesh villages to identify persons aged 35 to 65 years with presbyopia (presenting distance vision > = 6/12 bilaterally and correctable inability to see 6/13 at 40 cm with both eyes), who never had owned glasses. Participants were randomized (1:1) to receive immediate free reading glasses (intervention) or glasses delivered 8 months later (control). Visual demand of different jobs was stratified into three levels. Outcomes were between-group differences in the 8 month change in: self-reported monthly income (primary) and Near Vision Related Quality of Life (NVRQOL, secondary).
RESULTS
Among 10,884 census participants, 3,655 (33.6%) met vision criteria and 863 (23.6%) comprised a sample enriched for near vision-intensive jobs, but 39 (4.52%) could not be reached. All participants allocated to intervention (n = 423, 51.3%) and control (n = 401, 48.7%) received the appropriate intervention, and follow-up was available for 93.4% and 96.8% respectively. Groups were similar at baseline in all characteristics: mean age was 47 years, 50% were male, 35% literate, and about half engaged in "most near vision-intensive" occupations. Glasses wear at 8-month follow-up was 88.3% and 7.81% in intervention and control respectively. At baseline, both the intervention and control groups had a self-reported median monthly income of US$35.3. At endline, the median income for the intervention group was US$47.1 compared with US$35.3 for control, a difference of 33.4%. Predictors of greater income increase in multivariate models included intervention group allocation (OR 1.45, 95% CI 1.12, 1.88, P = 0.005), male sex (OR 2.41, 95% CI 1.84, 3.16, P <0.001), and not engaging in income-producing work at baseline (OR 2.35, 95% CI 1.69, 3.26, P<0.001).
CONCLUSION
Provision of reading glasses increases income in near vision-intensive occupations, and may facilitate return to work for those currently unemployed.
简介
远视是全球导致视力损害的主要原因，在工作年龄中很常见。然而，尚无试验评估远视对收入的影响。
方法
2017 年 4 月，我们对孟加拉国的 59 个村庄进行了普查，以确定 35 至 65 岁之间患有远视（双眼远距视力> = 6/12 且双眼矫正后无法看到 40 厘米处的 6/13）但从未戴过眼镜的人群。参与者被随机（1:1）分为接受即时免费阅读眼镜（干预组）或 8 个月后提供眼镜（对照组）。不同工作的视觉需求分为三个层次。主要结局是 8 个月时两组间自报告月收入（一级结局）和近视力相关生活质量（二级结局）的变化。
结果
在 10884 名普查参与者中，有 3655 名（33.6%）符合视力标准，863 名（23.6%）构成了近视力密集型工作的样本富集，但有 39 名（4.52%）无法联系。所有分配到干预组（n = 423，51.3%）和对照组（n = 401，48.7%）的参与者均接受了适当的干预，分别有 93.4%和 96.8%的参与者获得了随访。两组在基线时的所有特征均相似：平均年龄为 47 岁，50%为男性，35%识字，约一半从事“最需要近视力”的职业。8 个月随访时，干预组和对照组的眼镜佩戴率分别为 88.3%和 7.81%。在基线时，干预组和对照组的自报告月收入中位数均为 35.3 美元。在终点时，干预组的收入中位数为 47.1 美元，而对照组为 35.3 美元，差异为 33.4%。多元模型预测收入增加的因素包括干预组分配（比值比 1.45，95%置信区间 1.12，1.88，P = 0.005）、男性（比值比 2.41，95%置信区间 1.84，3.16，P<0.001）和基线时不从事有收入工作（比值比 2.35，95%置信区间 1.69，3.26，P<0.001）。
结论
提供阅读眼镜可增加近视力密集型职业的收入，并可能促进目前失业者重返工作岗位。
