Millions of people around the world have bad eyesight, but can’t afford the cost of eyeglasses. Children drop out of school as a result, grownups can’t find a job.

The physics and math teacher has devised a system that allows anyone, with just a bit of an introduction, to assemble eyeglasses. His small assembly set is already being successfully implemented in Ruanda, Tanzania and Burkina Faso.
