>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).
Interesting! Whereas here (Australia), at least in my region/social class/etc if I heard someone say "the eye doctor" I'd assume they're going to an ophthalmologist for surgery. Optometrists are their own category of healthcare worker.
Another English dialectical difference I wasn't aware of.
