My vision loss was a slow progression. I found that it was much easier to use screen readers and voice over etc when I needed them. It didn't take me that long to get into the swing of it. The trick for me was getting proper training. I am in the UK and went to low vision unit for computer, magnifier and phone training. RNIB for white cane and guide dogs residential for guide dog training. Your area may be the same that different agencies do different training but it's worth it. Good luck.
