There is this interesting article on BBC news about a call center in Mumbai(Bombay) which is meant for visually challenged people only.
I find this as a good sign, because people are thinking out of the traditional app roach that blind/handicapped people are only limited to a set of jobs.( If you've seen Black , there's a very nice dialogue that Amitabh has to reflect the same). Also, I am sure that this will give them a sense of achievement, and also , an all important, making them financially self sufficient.
Most importantly though, I feel that the fact that the person at the other end does not know that they are blind, will instill a great feeling of confidence since it gets rid of the (sometimes undesired) sympathy. Kudos to the people who got this great idea to work.
