New York - A 47-year-old man who was blinded by a chemical accident when he was  three can now see again,  thanks to a  revolutionary stem-cell  transplant. Mr .  Mike  May  had  feared  he  would  live  in darkness  the  rest  of  his  life. He  now  does  almost everything  anyone with  sight  does  - watch movies and play soccer with his sons. He also saw his wife for the first time following the surgery at a San Fransisco hospital. “A day doesn’t go by that I don’t appreciate the visual details  all  around me,  “Mr . Mike wrote on  a website devoted  to his experience.
