I was listening to The Take Away this morning on NPR. Its a great show! Today's Global Health International Segment, "A big vision for the future: a billion glasses for those in need", was very interesting. You can listen to this segment here.
"In sub-Saharan Africa vision and eye care services are costly and hard to come by. While 60-70% of people in wealthy nations wear corrective lenses, only 5% of people in the developing world wear glasses. Josh Silver, director of research at The Centre for Vision in the Developing World, has been working to make it easier for the world’s most destitute people to get glasses and keep them, even as they get older and their vision changes. He joins us now to talk about his efforts to bring sight to the world."
Joshua Silver's glasses are adjusted by pumping liquid into a thin sac in the plastic lenses. He wants the low-cost eye wear to go to poor countries where many can't afford conventional glasses.
