What does it mean for one eye to be dominant and how does it contribute to our vision?

Question

I’m curious about what exactly a dominant eye means, and what effect it has on how humans see the world

Answer 1

It’s akin to having a dominant hand. In many situations, it doesn’t matter, but it can matter when some things are designed a certain way or you need to see from a particular position.

Some effects come in when there’s “cross dominance,” for example being right-handed, but having a left-dominant eye, as I happen to be. When I shoot a pistol, I have to position my head differently to see the sights better than a right/right person would.
