The past two docs I've been two have ignored me when I've said "I can make out the letters, but they're blurry and fuzzy. Can we go stronger?" with "Well, that's corrected to 20/20 vision.".
I'm very, very strongly considering finding a used eye-testing-headgear thingie like they have in their offices, learning how to use it, and doing the testing for myself.
Maybe this is your sweet spot?
I doubt it. I played around a bit with the hand-lenses and was able to get a much more clear picture by increasing the lens strength more than the doctor was willing to.
If the doctor was making any sort of tradeoff, they were not informing me of it. They kept asserting that I was "corrected to 20/20" when I protested that the letters on the chart were still quite fuzzy. If they'd have informed me of a "close range vs. long range" lens tradeoff, I would have happily informed them of my willingness to have multiple pairs of glasses.
