When examining the pupil, it’s preferable to have the patient look into your own eyes. “Look into my eyes” should be left to horror movies and pickup bars, so a different approach is needed.
Let me explain how I learned what to say, and what not to say.
I used to say “Look at my nose, here”.
One patient said “why would I look at your nose hair?”
Now, I say “look at my glasses”. That works fine.
