Self-adjustable glasses make optical care accessible to impoverished areas of the world

Gotta love the do-it-yourself humanitarian nature of these lenses, whose strength can be adjusted by the user as needed. I don't think this sort of things would fly in the first world, where we've grown accustomed to trusting the experts for our prescriptions, but they seem destined for areas like sub-Sarahan Africa, in which the article states there is a mere one optometrist per million people.

And look at those hinges - much better than the dainty, brittle hinges we've got over here, eh?
