Can Someone Help?

Perhaps someone here at TFR can help with this.  If so, I would surely be grateful!

There is a member where I preach who is blind, and he desperately wants to be able to use a computer. He wasn’t born blind, but has just recently gone totally blind due to a degenerative disease. As a result, he’s not eligible for a lot of the financial help and such that those who are born blind receive.  I’m guessing there are some options for voice-controlled computers or something like that.  My main question is whether anyone on the list can advise as to the options, and we are especially looking for something that won’t cost a great deal; this gentleman is not living off government assistance, but he is by no means wealthy, either, so any option would have to be affordable.

If anyone can help, please comment below.  Thank you!
