I don't have any experience programming without visual aids; and you've probably already thought of this aspect though I'll mention it just in-case: if I were facing a similar situation, I would look into long-term disability insurance and see if there's anything I can do on that front. That way, I could still pursue being productive with blindness or deafblindness, but would have less economic pressure while doing so. Many employers offer a combination of short-term and long-term disability that will provide income (in some cases until you retire) in the event that you can no longer work.
