The doctor used an ophthalmoscope to check my eyesight during the examination.
Ophthalmoscope → It is formed from "ophthalmos" (from Greek "ὀφθαλμός", meaning eye) and "-scope" (from Greek "σκοπεῖν", meaning to look or examine). The word refers to an instrument used to look at the interior of the eye.
Think of 'ophthalmos' meaning 'eye' and '-scope' meaning 'to look' — this helps you remember that an ophthalmoscope is a tool for looking at the eye.
