Correcting an oversight: why do so many people still need eyeglasses?

Over a billion people need eyeglasses but do not have them, and providing eyeglasses to those who need them is a very cost effective technology for learning and productivity.  However, providing eyeglasses is not enough. In addition to supply-side constraints, demand-side constraints prevent people in need of glasses from buying and wearing them. We need to provide evidence for demand-side constraints. What are the demand-side barriers to wearing eyeglasses? How can we solve them? With this travel grant, the research team will survey people in Uganda who would gain a lot in terms of productivity by improving their vision, for example bus drivers, tailors, and weavers, to understand why they are not using eyeglasses despite the clear benefits.
