Hi - I think you’ve chosen a wonderful topic! I think your research question may be best tailored to fit someone who suddenly went blind (as opposed to born blind or gradual loss of vision), because it centers on the recognition of sensory improvement (blind people may not have this “noticeable improvement” if they’re blind from birth, and gradual loss of vision may correlate with gradual increase in various other sensory perceptions - this gradual improvement may not be noticeable, but I honestly don’t know).

I have gradual loss of vision, and I haven’t noticed any perceptible improvement in my other senses. Feel free to pm if I can help
