Ophthalmologist is derived from old Greek. I have never visited an eye doctor but I get my specs from an optician. Eye doctor makes sense as a concept and I have said it myself but is not routinely used.
The Normans brought Old French with them and that became the court language. Old English was more Saxon based. The classic examples of the effect of that invasion are meat vs animal names eg beef (French) and cow (Saxon).

You sure? At least where I live, you get an exam from an "eye doctor" (typically an optometrist) when you get a prescription. An optician fits and sells glasses. Ophthalmologists are M.D.s who have broader latitude in prescribing medications, etc.
This is one of the differences between UK and US English. In Britain, the term "eye doctor" just isn't used.
It's of a type with legislator vs law-maker; it's only really in the past few years that politicians in the UK have occasionally been referred to as law-makers.
Sure, I could have offered a better example, but the point is that English has enjoyed some wrenching integrations over time, Hastings having caused a big one.
