I have this condition, brought on in part by being born with cataracts.
Essentially my brain never learnt to correctly interpret the images from both eyes, so I don't have true binocular vision. I can consciously switch between which eye I'm looking out of, and I do get a little vision out of the other, albeit very blurry and with little focus (for example if I close one eye, my FOV gets slightly smaller).
It probably sounds a bit trivial but one of the worst things I find about not having binocular vision is it makes playing ball sports pretty hard (due to not being able to triangulate objects in the air). I love football but I can't head a ball to save my life, and as for stuff like fielding in cricket, if a ball is struck high in the air I've got no idea if I'm right underneath it or it's gonna drop 10 yards in front of me. It also makes me look a bit of a muppet if people throw me something in day-to-day life!
It sounds like you should be a member of this family!!
