If you look closely her head is slightly tilted forward so I think her forehead is what collided with the pole so the glasses didn’t get jarred too much.

Depends on your face. In my case, I would break my nose and crack my forehead before my glasses even touch the pole.
I'm more likely to bend my glasses by catching a basketball with my face.
I remember my mother walking straight into the tall window pan next to the door at olive garden while playing with her phone. Broke her nose, but her glasses were fine. (2 months latter they cut the panes half way up, making it pretty hard to make the same mistake again)
