目的评估未矫正屈光不正（URE）造成的视力损害对全球经济生产力的潜在影响。方法采用保守假设和国家人口、流行病学和经济学数据，估算所有视力损害者的购买力平价调整的国内生产总值（PPP调整的GDP）损失。结果-估计有158.1万例视力障碍导致未矫正或矫正不足的屈光不正在2007年，其中870万人失明。我们估计，按国际美元计算，与这一负担相关的全球经济生产力损失在按具体国家的劳动力参与率和就业率调整之前为4 277亿美元，调整之后为2 688亿美元。用同样的调整，但假设没有经济生产力的个人年龄>= 50 years，我们估计潜在的生产力损失为1 $121.4 billion.Conclusion即使在最保守的假设下，总的估计生产力损失，在$I，与视力障碍从URE是大约一千倍以上的全球病例数。扩大现有的屈光服务以满足这一负担的成本是未知的，但如果每个受影响的个人被提供以低于11000美元的适当的眼镜，净经济收益可能是可以实现的。
Objective To estimate the potential global economic productivity loss associated with the existing burden of visual impairment from uncorrected refractive error (URE).Methods Conservative assumptions and national population, epidemiological and economic data were used to estimate the purchasing power parity-adjusted gross domestic product (PPP-adjusted GDP) loss for all individuals with impaired vision. and blindness, and for individuals with normal sight who provide them with informal care.Findings An estimated 158.1 million cases of visual impairment resulted from uncorrected or undercorrected refractive error in 2007; of these, 8.7 million were blind. We estimated the global economic productivity loss in international dollars (I$) associated with this burden at I$ 427.7 billion before, and I$ 268.8 billion after, adjustment for country-specific labour force participation and employment rates. With the same adjustment, but assuming no economic productivity for individuals aged >= 50 years, we estimated the potential productivity loss at 1$ 121.4 billion.Conclusion Even under the most conservative assumptions, the total estimated productivity loss, in $I, associated with visual impairment from URE is approximately a thousand times greater than the global number of cases. The cost of scaling up existing refractive services to meet this burden is unknown, but if each affected individual were to be provided with appropriate eyeglasses for less than 1$ 1000, a net economic gain may be attainable.
