Displays having varied virtual object distance across field of view

Abstract

A display may include waveguides that direct image light overlaid with world light to eye boxes within a field of view (FOV). Lenses may transmit the image and world light to the eye boxes and may have different powers at different elevation angles across the field of view. This may serve to place virtual objects from the image light at different image distances when the virtual objects are in different portions of the FOV. For example, the lenses may place the virtual objects at closer image distances within lower portions and farther image distances within higher portions of the FOV to align the image distances with the most likely distances to external objects from the world light, thereby mitigating focus conflict. The virtual objects may be adjusted based on a gaze tracking location to overcome vergence accommodation conflict and/or to compensate for different positions of the user's eyes.
