One eye shooter
I have what they call a lacy eye, my left eye is working perfect, but I just don’t use it.
Some connection in my head decided not to use the left eye, long time ago.
It doesn’t affect me in daily life, but I don’t measure distance the same way you would do with two eyes, I have to recognize the distance.
This is however a great setup when you want to aim over a gun barrel, for me there is no deference if I look true binoculars or a scope.
Now this is just theory, since I haven’t tried the two eye setup, but when using open sights, I would keep both eyes open, and avoid changing the depth recognizing technique.
