Optometrists/opticians aren’t doctors over here though. They belong to the trades. This field doesn’t exist in Germany the same way it does in the US/Britain:

Optometric tasks are performed by ophthalmologists and professionally trained and certified opticians.

Eye doctors does actually refer to ophthalmologist though, I picked the “wrong” translation which ignores the differing legal frameworks. Looking back, I certainly went to the full blown ophthalmologist just for optometric purposes.
