Claim:
1. A method for displaying virtual objects with variable focus by an augmented reality system comprising: identifying by one or more processors a three dimensional location of one or more virtual objects within a user field of view of a near-eye display device of the augmented reality system, the near-eye display device comprising a microdisplay assembly and a display unit optically coupled to receive one or more images from the microdisplay assembly; determining by the one or more processors a three dimensional focal region of a user wearing the near-eye display device within the user field of view; identifying which of the one or more virtual objects are in the focal region of the user based on the three dimensional locations of the one or more virtual objects within the user field of view; generating a series of layered image data at different user focal regions, by the microdisplay assembly, for each of the one or more virtual objects, such that the one or more virtual objects are identified as being in the user focal region; and receiving from the microdisplay assembly and displaying by the display unit the generated image data of the one or more virtual objects.
