I think you are confusing two separate issues. I struggle to do still life as well, when the subject is right in front of me. That's not due to eyesight problems. My visualisation is not perfect but is much better than anything I can draw. However, when I have taken art classes and I practised, my skills improved... Much like music or chess. If I stop practising drawing then my skills deteriorate.
I can write about things in far more detail than I can draw them. Both from my imagination and sometimes memory. I can remember the floor plan of certain buildings I haven't set foot in for over thirty years. (Or at least the parts I had access to.) I can remember which direction they are orientated in, and where the sun rose and set in relation to them. As me to do a drawing, as opposed to a diagram, and I will struggle due to poor art skills.
My drawing skills are more to do with the fact I have mild dyspraxia than my ability to visualise. My handwriting is pretty atrocious too for similar reasons. My visualisation skills are far from perfect but still much better than anything I can draw.
