Probably means "don't count on it, but I've seen it many times before".

leave you now with a level of vision that still represents a retrograde

motion (albeit smaller) since you first got corrected, it could still be consistent with my uninformed musing.

Its well known that folks become far-sighted (short-armed 8-) with age. Its well known that close-work leads to near-sightedness, or you might just be born with it. So you might think they would cross over at some point --leading to retrograde acuity. I'm nearing 40 and it hasn't happened yet, though I haven't asked my optometrist to plot the second derivative of my resolution. Its encouraging to find that Neil is benefitting from age. He chose better ancestors in that respect than me.
