This is the type of innovation that we need more of – the type of inovation that puts expensive medicine in the hands of lay people. Maybe one day telemedicine will offer a low-cost, viable business alternative to traditional health care for most common problems? I could imagine something like this: if you dont have an optician nearby, online glasses discounter advertises, send in your retinal image and we'll make cheap prescription glasses for you!
