Eyeglasses are as old as the Renaissance, but even now we still need trained professionals to fit them, it’s a nightmare for developing countries. In sub-Saharan Africa, for example, there’s only one optometrist for around 1 million people. There optmetrists and eye doctors are badly needly to check eyeglasses pescription for the local people. That’s no problem for the Western world, such as USA, which has around one optometrist for roughly every 10,000 people. People in USA can get their glasses prescription very quickly.
So I think we should do something for the people there, we can gather our unwanted eyeglasses, recheck the used glasses and sent them to the poor people. If we can collect a lot of eyeglasses, we also can sent some optometrist work there so that the people there can get more correct prescription glassses.
