Simple thought experiment:


Imagine that the amount of depth of field blur was just based on whether or not the reflective or refractive surface was in focus, then how would a camera lens work? If focus was on the front glass element of the camera itself, then everything would be in focus, and if focus was anywhere else, then everything would be out of focus.
