A ground-breaking study, published in the Bulletin of the World Health Organization, demonstrates that every dollar spent on refractive error or cataract correction produces $36 in benefits, on par with other 'Best Buys' in international development. To uncover this finding, a team of researchers first conducted a systematic review, identifying all peer-reviewed studies published since 2001 that estimated productivity, learning and welfare impacts from correcting refractive error and cataract. Using benefit-cost analysis, the report meticulously and transparently quantifies the return on investment of 21 identified studies across 10 low-and-middle-income countries. With a median return of $36 for every $1 invested the paper presents an unequivocal case for action on eye health.
