Yes, it is. It will sometimes try to create information that doesn't exist.
Off-topic, but an interesting example of that... there's a type of contact lens called "monovision" that's designed for people who need bifocals but can't get bifocal contacts to work well. Actually, it's not a lens type at all, it's a setup. You put a distance correction lens in one eye, and a near-vision correction lens in the other, and after a day or two of that your brain can't tell the difference. It automatically compensates.
I had a set like that for a while, but eventually gave up on them. Everything does work as advertised, but if you get into a situation where only one eye can see, it has to be the properly compensated one for the view you're looking at. The trick only works when both eyes see the same thing. So, if you're doing up-close work and trying to peer between two PC boards, for instance, you have to make sure the eye that's corrected for near vision is the one doing the looking. It's not always possible, so you end up in less-than-ideal situations.
But, that's contacts for you anyway. They're a vanity move much more than a practical one.
