Double vision: True binocular diplopia is due to misalignment of the eyes. This can be due to a CNS or PNS lesion. "Double vision" in just one eye is ALWAYS an eye problem, NEVER a brain or nerve problem. So one is nervous system, the other is eye. These are very important diagnostic distinctions. "Eye" is what ophthalmologists do; "nervous system" is what neuro-ophthalmologists do.
