I’m going to qualify this—all vertebrate eyes have a blind spot. Cephalopods also have eyes that are like vertebrates (this type of eye is called ‘camera eyes’), but their eye anatomy is such that no blind spot exists for them.

Piggybacking on your fact about the brain effectively editing what we visually perceive, we don’t see our nose (unless you made a concerted effort to look at it) because the brain ignores it.
