Axial length is adjusted by accommodation and defocus. It seems reducing too quickly keeps you in blur/polyopia that you cannot overcome, which gives you shorter axial length, so you'll pay the price of extra accommodation strain while you revisit those old diopters. The solution is to "revisit old diopters" to have polyopia that you can overcome, and then reduce after you overcome them, which was very fast for me, at 0.25 D in 5 days. | Axial length is adjusted by accommodation and defocus.

I find that AF is the one-and-only true eye exercise. Combining the habit-fixing and gradual lens reduction of EndMyopia, the control system model from Otis Brown (his posts are in a really weird style though, and I think "extra" accommodation is subtracted, possibly making strong plus lens bad, even for near work, as they might induce hyperopia), and the concept of eye exercises (but using one that actually works, instead of other ones that don't) seems to result in really fast gains compared to knowing only one alone (EM doesn't advocate for exercise until you are a pro, control system model doesn't account for polyopia resolution, and eye exercises that are not AF don't affect refraction). Perhaps the axial length would take time to resolve if I didn't solve it while I was "blur-adapted". | I find that AF is the one-and-only true eye exercise.
