When someone sees any possible detail that changes one person from another. This vision is often used to tell how someone feels, or how old someone is. The better your vision, the easier it is to tell the traits of someone just by looking at them.
Merlin has a really good artist's vision. He asked this one chick about herself saying stuff like, "Are you 15?" and he was right about everything!
