Does #1 mean #2 or #3?

Answer 1

Are you writing about the glasses (spectacles) people wear to improve their eyesight?

Rather than "arms" we use the term "temples" or "temple pieces" --

#1 can mean either #2 or #3.
#2 means she's not wearing them, but she's holding them in her hands.
#3 means she has them on her face correctly so she can see through the lenses.
