Hmmm .....
I wonder if the dominant eye thing is more related to practical opportunity, unlike handedness. Cameras are geared towards right handed people, since the shutter release and winder are almost always on the right. The viewfinder is on the left in order to make the right side of the camera accessible to the right hand.
This begs the question, are left handed people also left eye dominant, and are right handed people generally right eye dominant, or is eye dominance not strongly correlated to hand dominance? I don't know the answer, but it's certainly an interesting phenomenon.
