Vision update: could get a 20/25 line and about half a 20/20 line with both eyes and with the right eye alone. (Left eye is a bit weaker, about 20/40). Blur-free visual range is 52-56 inches, suggesting nearsightedness in the range 0.70-0.77 diopters.
Still super dependent on ambient lighting: when not in direct sunlight my vision seems more like 20/40 or a bit better
