20/20 vision is 1 arc minute, and many people can do better than this.

Naturally this assumes excellent contrast...

Great info, my observing eye tested as 20/10, what size can be resolved with this vision?

I think that's twice as good as 'normal' you see at 20 feet what most people can do at 20.

So this means that with this vision 1 arc min can be seen? I read that visual acuity can still increase down past 1mm exit pupil, with decreasing acuity gains the farther we go- law of diminishing returns, but it still increases.

Great Link Stub! very interesting stuff.
