Question

Hello all! :) thanks for reading! I was just wondering if anyone can give me some input on where to start... I really want to teach the blind children of america, I just don't know where to start! A lady at work was telling me to become a "Vision Teacher".... How is the jobs in this field? If anyone has any kind of information, let me know!! Thanks!! :) :)
