The evidence that sight restoration alleviates poverty
Research carried out in Bangladesh, Kenya and the Philippines by The London School of Hygiene and Tropical Medicine found that blindness causes poverty, and that restoring sight improves the economic status of individuals and families. They found people who had cataracts, and compared them with people in similar situations who did not.
Expenditure in households where an adult had cataract was lower than in non-cataract cases. Cataract households were checked before and a year after surgery – results showed that the gap in expenditure across the different types of households was dramatically narrowed.
