Focus Night & Day update (cornea lens down)
Wow, this is getting more and more interesting...

uttered like so:
Not being a doc, I have no idea what happens medically, but
intuitively it would seem to me that if I am wearing a lens that is
steep relative to my cornea, which I would guess is more likely for me
because my K readings are somewhat flat, then it would sort of
"squeeze" the cornea into a steeper topography, like what would happen
if you squeezed the top of a balloon with your hand. Am I visualizing
this properly? If so, then based on what you said above, I should be
getting more myopic over time, which *seems* to be what happened to me
over a span of the last week.
Those are certainly some fascinating statistics, Larry! I rarely
slept in my last pair of (non-silicone) lenses, so I am guessing that
any changes going on in my cornea are not due to a "healing" of edema
due to renewed oxygen availability. I could be wrong though--you'd
know better than me. I am definitely interested in trying extended
wear in these Focus N&Ds, so perhaps I can expect my power to reverse
and go back down to where it was before!
My lens fitter did tell me that in her experience, people who wear
Focus Night & Day lenses tend to need a more negative power than they
would with other lenses. That made me wonder if CIBA labels the power
of these lenses differently than other manufacturers do, but now I see
that it may be due to corneal changes.
I find that fascinating!
