Suppose it is true that corrective negative lenses to compensate for
myopia myopia does indeed lead to progressive myopia. (Don't jump on me
yet.) How could such putative knowledge  be used to cure hyperopia?

Suppose enough positive power is used to correct a young child's
hyperopia so that reading distance is moved in to be closer than typical
reading distance. That is, the far point is brought into where the
normal near point would be. Then I would expect that all the visual
behavior with such positive lenses would be pretty much the same as that
of a myope. Would that cause the eyeball to lengthen? I sure do not know.

Such technique is probably testable on animal models. Other strategies
might hold even more promise.
