Many agricultural workers don’t have the eyesight they need for the work they do, affecting both their comfort and their ability to earn more money. They're among the billion plus people who have visual impairments but can't get the assistance they need. We visit a coffee plantation in southern India where workers are being given glasses on the spot.
