That is how I shoot a rifle (x-military). I photograph sports and keeping both eyes open help keep you safe. I get a lot of eye strain and can view with either eye

I always shoot with both eyes open. I do street and want to see all around me. For subjects as well as my safety.

the best advice I have ever seen on this forum is: "Do what works best for yourself!"

While I agree with using two eyes for tracking moving objects, there can be a problem when you are doing stills. When you use two eyes you are seeing in 3D, and while something may pop out at you, it is frequently the brain making it stand out. I used to carry a slide mount - empty - with me to force me to see a scene in two dimensions, just as film/sensors do, by closing one eye and using the mount to outline the framing for me. We probably all have joked about film/video directors making a rectangular frame with their hands and looking at a scene with one eye. It is not just to get the framing, but to see how the scene will actually be recorded.

I've tried both, and don't see any difference. But, then, my left eye is artificial.

I do alot of events and have to move around alot. When the camera is at my face you can bet your "sweet bippy" I keep both eyes open at least when I can.

It more difficult at extreme telephoto lengths and nearly impossible in very bright or dark environments. Only during these times I find myself using one eye.

Plain and simple, use one eye and I might miss something important to shoot, or it's very possible I could trip and fall on something or destroy it. One example could be at a music event and kick the singers cord out of the amplifier.
