It could be genetics. My mothers eyesight was extremely good, and last time I checked, my son's binocular acuity was between 5" and 10" better than mine.

My preferred natural targets for testing are high contrast twigs against the sky at somewhere around 150 to 250m, but I can get pretty close with messy ones if the light is good. My son is better than me on those. My optometrist tells me it's not only my acuity, but my perception that is is rather unusual too, but I know very well there are others that can better me.

That is amazing. Your whole family should consider amateur astronomy as a hobby :)
