Jon’s detailed update reflects what you should experience. Initial quick adjustment (some part overprescription usually, and some part less focusing muscle spasm), and then ongoing gradual improvement. The more you follow Alex’ recommendations and stay involved in the beginning, the more reliably you will see ongoing progress in the long run.
An aside, for those of you wondering what may have gotten into Jake in this recent article.
I’m sure sometime soon we will get something talking more about axial change. A fair bit of e-mail has come in with people really worried! You do have to read between the lines sometimes with Jake. Of course axial change is real – it’s a rather interesting subject, with plenty of conjecture. To fully appreciate the subject one may have to read a fair bit to get a sense of who the authors of various studies are, their background, and goals.
If you are just thinking of your eyes though, rest assured, your eyes are indeed a dynamic system. They do adjust to prevalent focal plane, including one of the core mechanisms for that purpose, the length of the eyeball. If that were not the case, you wouldn’t be able to improve much of your eyesight (and there are lots of first hand accounts to the contrary, here).
Hopefully Jake will provide us with more good reading on the axial change front, soon. :-)
