I'm nearly blind in my left eye (was born with a cataract; lens was removed at an early age before lens transplants were a thing) and I think I perhaps experience something similar. My vision isn't really integrated between the two eyes. It's hard to explain. I "think" with my right (good) eye. But then I also sort of have this auxiliary eye, my left eye. I can just see vague shapes and colors through it. It's just like this... separate camera or something. I can basically pay attention to one eye or the other; they're not really "together." Now obviously, unlike these twins, I don't have another person controlling it. But, I wonder if their experience is similar to mine. Like they have their "primary" eyes and then also this separate disconnected set of eyes they can pay attention to if needed/wanted.

I have normal vision (with glasses) in both eyes, but I also have strabismus, that is, one eye turns inward a bit; so rather than seeing double, I use one eye at a time, and can switch from one to the other voluntarily. I just get peripheral vision from the "off" eye. I don't miss the depth perception much, but it does mean I get nothing from 3D glasses. With the modern polarized kind I can at least wear them and watch the movie normally; with the old red/blue kind, the whole movie would be red or blue depending on which eye I was using.

  I've experienced something similar. I kind of think that the other eye is still working and providing some depth perception, it's either that or after lifetime of single eye dominance/usage you just adapt and become very good at estimating and judging depth and distance. In my case never having normal vision, I don't really know what I am missing, if anything.

    Yeah! I did some reading and apparently binocular depth perception is the least important kind, and only works out to about six feet anyway; past that there's not enough parallax between your eyes to get any useful info. Judging distance by an object's surroundings is the most common way of doing it even for people with normal vision.
