Went back to the independant eye professional, not a Walmart employee. She
put me on the gadget, and dialed in some correction. When she finished, I
glanced at the numbers on the front of the dial a focuss. And they were the
same numbers as my prescription from 2007.

I'll admit, I'm puzzled. My year 2007 eye glasses aren't strong enough. They
sure don't behave like the dial a focuss eye gadget did. I had another pair
of Zennis, which the other optician checked, and finds it's the same as my
2007 prescription. Those were not strong enough.

Do glasses change their focusss over the years? Does the focuss change, if
glasses are in storage?

The development of cataracts can do that, and they don't have to be
very big to affect vision. Cataracts in the central area of vision
will affect vision more than if the changes begin somewhere else in
the lens. When cataracts interfere with vision, the phoropter reports
the best correction for each eye, but it doesn't mean that you can see
20/20. There could be other reasons for that, but this was my
experience prior to having my cataracts out.
