Anyone else have partial blindness, you mean? No. That sucks big time.
I have "polyopia" as a result of RK. I see 3 front sights, and have to put the big blob of front sights on the target. I just have to resign myself to the fact that I will never shoot as well as somebody who only sees one sight.
If I were you, before spending money, I would borrow and try out as many guns as I could, with different sights. Try fiber optic, but also try the XS Express sight with the honkin' big dot.
