So you don't look at the target at all? Like you're only looking at the sights and hope there is a target downrange somewhere? No - right? Because "most people aim below the target" right? And near-sighted people wouldn't need glasses at all if they "didn't look at the target". I don't doubt that the focus is on the sights, but the sights are pointing at something... right?

So what I'm wondering is - what is the point of an adjustable aperture on her lens then? I was speculating that it's because it would keep the tiny distant target in focus while she also lines up the sights. Or maybe it helps keep the near and far posts of the sights in focus at the same time? Human vision can have a pretty narrow depth of field.

And in fact it seems that my speculation may be correct: https://www.pyramydair.com/blog/2008/06/10-meter-pistol-shooting-part-4/

"Because the light is reduced, the shooter’s eye acts like a camera lens and adjusts the depth of field (range of distances at which objects appear in focus) to the maximum. That’s what keeps both the sight picture and the bullseye in sharp focus, but the shooter wants the front sight to be in the sharpest focus, because it’s what he focuses on."

So you get a sharper target while focusing on the very close (by comparison) sight.
