Right handed, right eyed. I don't think I can close my right eye and leave my left eye open.

Right handed, left eye dominant so I use my left eye.

Same. I get all discombobulated when I've tried shooting with my r/h & left-eye. I constantly open my left eye while moving about positioning myself, however. I shoot on-location 90% of the time, and luckily all the spills I've taken so far I was able to soften in time with a left-arm or butt-cheek

IMHO alone, as always;

Lefty, in hand and eye.

I am right handed but now left eyed. I was right eyed until my stroke. Making the switch was easy and almost instantaneous. That makes me think that eye dominance is at least in part habit.

Right handed.  Either eye depending on camera angle with respect to body position, especially when shooting sports.   Both usually both eyes open and non-viewfinder eye used to aid tracking and catch events outside of viewfinder.    For more slow paced and posed or artistic work where I'm concentrating more on composition and less worried about missing some action, I tend to favor right eye and close the left.

Right handed, right eye generally, with both eyes left open for the most part. Same when I shoot vids. With certain camera angles I sometimes use my left eye to the viewfinder.

I have been experimenting with both eyes closed and shooting in the direction I hear though! j/k
