I thought maybe you were second guessing yourself. Double - or blurry - vision is from the eye muscles being weak, causing them to focus in more variable ways. Sometimes you can see double vision in the front or on the sides, sometimes close up and sometimes farther away! And if both eyes are equally "droopy" you don't have blurry or double vision, even if the muscles are weak because they are equally weak!
I really hope the appointment goes well. I hate what neurologists tend to do to patients. They add to our "doubt" instead of reassuring us. It's normal to question what the truth is or isn't but it's not normal to doubt your patient!
Good luck on the 17th.
