Apple also has some Augmented reality glasses like googles iGlasses

From and article back a while in mac life.
In mid-April of 2008, Apple published a patent for a “Head Mounted Display System.”  The patent shows screens and fiber optics and vision imaging controls.  Would the display use pico projection or utilize OLED displays?  Pico displays could be used right now, but OLEDs might be a year out.
