1) Your original post I responded to was talking about oculus rift; while it may be possible to use the oculus rift outdoors or untethered, it's definitely not currently being developed for that use case.
2) FWIW, world lens is described as augmented reality. Also, it has a much narrower FOV, probably doesn't update in real-time (and probably doesn't need to), doesn't require wearing a bulky headset, doesn't occlude your entire FOV, and in any case, is not connected to an oculus rift.
