Once you're at this level, you're looking to get improvements of a fraction of a percentage. I don't know the specifics cause I'm not a pro shooter despite being American, but from other high level skill people I know, you hit a point where improvements basically plateau and you have to resort to increasingly niche products to obtain non skill improvements. If you want proof of that, check out calligraphy and fountain pen communities. The amount of money some people spend on things I didn't know existed is wild.

(No bad judgement to those folks, I've gotten hard into map making and 3d printing lately, so I'm right behind you)

Adjustable frames help keep the lens at the correct angle for your eyes if you tilt your head a certain way from my understanding. So if you tilt your head at a certain angle you can adjust the frame to keep your prescription from getting out of focus at that specific head tilt

It is also an adjustable, external retina that allows you to let just enough light through, apparently.

if you look closely you can actually see a literal blinder over her left eye! the reason it helps is because precision shooting is all about repeatability, and both eyes open is a more repeatable position than closing one eye exactly the same way every time
