>But what I'm more interested in - is it common to _call_ an optometrist a doctor in the US? As opposed to an opthalmologist? Or is this just a weirdness in this article?
People, at least here in Indy, don't (generally) say "I'm going to the optometrist" we say "I'm going to the eye doctor" because they are doctors (they've obtained a Doctor of Optometry degree).
