We all know how important it is to give back. Some of us do it through our work, some of us volunteer, and some of us donate. But when you donate, do you know where your money goes, and how the organization uses it? Ahead of World Sight Day 2019, Sightsavers is using Twitter to share the stories of the real-life application of their money and resources, showing you the ways in which a donation (or a few volunteer hours) actually changes someone's life. Head over to Sightsavers on Twitter to hear the stories, and to vote on what kind of story you'd like to hear next.
