Dear Mr. Know,

          My 13-year-old son was in an accident several days ago. His doctors say he has no chance of

seeing again. I have no experience with the blind (盲的). I want to know how he may behave in the

future. I want to know everything I can to help him. Please help!

Dear Mary, 

          My son, Trey, who is nine years old, also lost his vision (视力) suddenly. I think one of the most

important things for you to do is to find other blind kids of your son’s age in your area. He will need

someone to talk to that understands his situation and can give him some advice. Sometimes, other kids

treat your son differently, and it takes time, experience, and patience to learn the best ways of dealing

with this. But if your son had another successful, blind teenager to talk to, that person could tell him how

they dealt with the same situations. Also, often talk to the doctor so that they can show your son how to

get around safely. Learning to use assistant technology(辅助技术) and Braille(盲人用的点字法) are

also extremely important. Where I live, we have a place called Envision that offers these services. Check

around for something similar in your area. I hope I have been of some  help.
