Those sets of trial lenses and frames..... I want one.  I think that if
I played around with them for half an hour, the mystery of my
distance/astigmatism correction would be solved.  (Or possibly not; but
at least I'd find out.)

18 years ago when I was 17 I was told I had keratoconus, and I started
wearing Gas Permeable Lenses.
I have been moving around the world a bit ever since then and have

Cataracts in both eyes. Nuclear in the left,  subcapsular in the right.
Eye doctor recently told me I'm losing more distance vision. Left eye
