New York Times: A Simple Way to Improve a Billion Lives: Eyeglasses
“…More than a billion people around the world need eyeglasses but don’t have them, researchers say, an affliction long overlooked on lists of public health priorities. Some estimates put that figure closer to 2.5 billion people. … Then there are the tens of millions of children … across the world whose families cannot afford an eye exam or the prescription eyeglasses that would help them excel in school. … The World Health Organization has estimated the problem costs the global economy more than $200 billion annually in lost productivity…” (Jacobs, 5/5).
