Same here - but I can switch my vision for screen tasks to either only near-sighted (by being about 25cm away), or to far-sighted (by being about 70cm away). If I am doing that in the middle of the task, it feels a tiny bit “strange”.
Ah I see what you mean. For me I don't think there is any distance where both near & far eye could each have focus -- it's always too blurry in one or the other. I could see how being able to consciously switch would feel weird!
I'm curious -- if you held a stereogram at the right distance, could you see the 3D image? Or is it also like me, only one eye at a time?
I had to do a little bit of “cross-eyeing” and then I can see something that does look like 3D. That said, my eyes are a little weird this way - back in childhood I trained to move them separately as well - a great party trick to freak out the people ! :-))
