I know lots of people who are coulour blind, but that means that they can't see certain coulours like other people. But that doesn't mean that they become blind completly. Yes they can become coulour blind for life, but not blind blind.
"There are many, many jobs for blind people out there. It's just like anyone else, blind people can do anything they want." So many jobs for blind people are available. The American Foundation for the Blind focuses on helping blind people find employment in the United States.
