As for the eye trick... note the "padding" on the end - sits nicely over the eye socket.... BUT... still requires some skill to be able to withstand such forces.
As for throat... there are ways to toughen the connective tissue in that area to withstand some force, but for forces of that nature involved in bending an iron bar, that still requires some sort of strength/development.
