Like a few others, I had to be competent with right or left hand shooting, and behind barricades, to use my left eye only. I usually managed to shoot a possible several times of the year.
The human mind and psyche are wonderful things, they can get used to almost impossible situations and difficulties. I am sure that, just as we compensate for elevation, we will be able to adjust windage (left/right), no matter what the recoil situation is.
