You still haven’t told us which physical structure changed. If you ever
figure that out, you’ll realize we’re right. Here’s a hint: when you
eliminate the impossible, whatever is left, no matter how improbable, must
be the truth.
Hanging a piece of convex plastic in the visual path doesn’t change the
length of the eye or the curvature of the cornea. Perhaps you believe it
does, but then, that is YOUR PROBLEM.
You can evade the issue by saying the eye isn’t a box-camera, but the only
other explanation is that some miracle happens between the cornea and the
brain, and that isn’t really scientific, now, is it?

Dear Otis Engineer,
More argument just for the sake of argument.
Your case study, Shawn, is an accommodative myope. Inducing ciliary muscle
relaxation by the use of plus lenses is certainly going to help such people
in the long run if they are willing to do it. So would be the use of
atropine to paralyze their ciliary muscle. No argument from any of us
there. Accommodative myopes are in the minority. The majority of myopes
are due to structural/anatomical issues within the eye.
But you keep avoiding the issue. Please answer the question that you keep
getting posed with–
In an anatomical myope, where the axial length of the eye is too long or the
corneal refractive surface it too steep, how will a plus lens cause the
visual image to be brought to focus on the retina? What anatomic structure
in the eye is changed to achieve this? Do you propose that the length of
the eye shortens? Do you propose that the curvature cornea flattens? Do
you propose that the index of refraction of the ocular tissues decreases?
Or some other fiction? Try to answer the question Otis.

Ph.D. O.D.
P.S. — If you oppose using minus lenses so much, how can you claim in a
separate posting in this newsgroup to be neutral toward the use of LASIK
surgery to correct myopia. In LASIK surgery you are simply removing plus
power from the cornea (equivalent to adding minus lens power) to get the
visual image to focus on the retina?
