Questions from a newbie shooter with a scope

[RifleEnthusiast]

I get a similar effect shooting through an aperture. Do you have both eyes open? I find it helps. If this freaks out your sight picture, try glasses with one lens frosted (scotch tape). You still want light coming into the unused eye.
I find I can close my eyes for three seconds and it all comes back. You'll end up practicing your "natural point of aim" techniques so everything is still there when you open your eyes again. I've also heard that eyesight degrades with oxygen loss, so maybe breathe deep a bit before holding your breath for the shot.

Typically I have both eyes open, with a patch over left eye of the glasses. I will try focusing more on the reticle as well as playing a little bit with the reticle focus setting.
