I was still unable to do this, not sure what I am doing wrong, but I can't get over the sense that I am always directing only one of my eyes. I can't move them independently.
In this case, you aren't directing your eyes, but instead looking through the object. Start with your finger about 6-8 inches from your face, and look at your screen. You'll see two fingers. Now try to look past your screen. The farther you are from the object the harder it is.
I don't follow this part, still. Do you mean computer screen / phone screen behind my finger which I would try to look at?
I can switch between my left and right eye when I concentrate, but I can't see both at once. I can try to rapidly switch from left to right to back, but it takes a lot of effort, and it's never the same image at once?
My right eye is dominant, I can switch to left eye if I focus hard, but I can't merge both or can I?
Edit:
I tried putting a paper between my eyes, so right eye would only see right part and left eye only left, am I supposed to see the whole image at once then combining the inputs from both eyes at the same time? Because I can only see left or right, as if my other eye was closed, even though it's not.
For me, when I look past my finger, I see two and each is sort of transparent as the image of each eye is transposed over the other. Maybe you can only see one at a time?
Finally after some time of trying I was kind of able to see 2 fingers, but I think I have some sort of condition that means I mostly have monocular vision compared to binocular vision, which most people seem to have. I am still trying to understand how different I see things from most people. But this is something I never realized.
My brain really prefers to process from only one eye at a time, it seems. I wasn't able to get further than the 2 fingers even after more than a hour of trying. E.g. I wasn't able to duplicate anything on my screen.
Weird that I only now realize this after decades of living. I wonder what impacts has it had on my depth perception etc.
