Found these on Frankonia Jagd, and elsewhere. Anyone tried them, I thought they could be nice for some outdoors pistol shooting?

I'm at a loss as to how can these multi iris lens be of benefit. As far as I know, consistent and repeatable head position is a part of accurate shooting. If you happen to change holes in those lenses from shot to shot, consistency is lost. I'm English only, so maybe being able to read that web page would help me some?
