Same here: it's called "accommodative excess". And in particular, it won't show up on a vision test.

I always got 20/20 on my vision tests, but kept complaining to different optometrists, and finally found one smart enough to recognize my situation, and now I wear -0.5 lenses. It brought my life out of a very dark place.

That hits a nerve for me. Sure I get 20/20 but if the astigmatism doesn't line up I'm going to have a bad time.
