Definitely not as bad as the author, but slowly losing quality of vision is a nightmare for me. I'm very sensitive to any kind of changes and ~4 years ago my eyesight began to rapidly decline. It's still in very low numbers, but it already affected the comfort of how I live. Without glasses everything is blurry and gives me nausea, with glasses I can see, but it's not the same as having perfect vision. Myopia + Presbyopia, 30yo. It's been ~8 months since last prescription and I already need it updated. Every morning putting on glasses make my eyes hurt for first half hour or so, getting used to "focusing distance" readjustment still. Some days eyes simply feel tired and refuse to focus, yet after doing all the tests, nothing extraordinary was found about my eye issues...
I had an eye doctor assure me that my discomfort with my new glasses was normal and that I'd just have to get used to it. After several months of nausea and discomfort, I finally went to a new eye doctor that fixed the problem immediately with a different frame and fit. It turned out that the prescription was correct, but the fit was wrong.
Before accepting daily discomfort and nausea as a new norm, you may want to try having more than one eye doctor look at it, if you haven't already, for alternate opinions for tests and on all the parameters of fit. There's alot that goes into getting your vision corrected and a few tiny adjustments off can end up causing persistent nausea and discomfort similar to what you are describing.
Do you sometimes have less pain right when you wake up in the morning? Sometimes worse pain in the middle of the night? Permanent redness / new blood vessels? VERY dry? Have they changed shape (more pointy than round, prominent cone like outline against your lower eye lid when you look down)? Yellowing?
Sigh.
