M: John Wilson was an Englishman who worked to prevent blindness in the developing world. When he was 12 years old, he was blinded in both eyes during an experiment in science class. After that, he went to a school for the blind where he learned Braille（布莱叶盲文）, which is the writing system for people who can't see. Then he studied law at the University of Oxford. After Wilson graduated, he went to Africa. There, he was shocked to find widespread blindness not caused by accidents, as in his own case, but resulting from the lack of effective treatment for certain diseases. For decades, he led an organization to prevent such blindness in Africa through education, research and health care. For example, a disease spread by insects blinded 10% of the people in a part of Ghana, but in the 1950s his organization distributed a drug that nearly eliminated（消除）the disease by 1960. In addition, it helped reduce the number of blind children by giving out vitamins and also by performing over three million eye operations. As a result, millions of people who were in danger of becoming blind have been treated, and blindness is less common there now.
