Abstract: Methods and systems for depth-based foveated rendering in the display system are disclosed. The display system may be an augmented reality display system configured to provide virtual content on a plurality of depth planes using different wavefront divergence. Some embodiments include monitoring eye orientations of a user of a display system based on detected sensor information. A fixation point is determined based on the eye orientations, the fixation point representing a three-dimensional location with respect to a field of view. Location information of virtual objects to present is obtained, with the location information indicating three-dimensional positions of the virtual objects. Resolutions of at least one virtual object is adjusted based on a proximity of the at least one virtual object to the fixation point. The virtual objects are presented to a user by display system with the at least one virtual object being rendered according to the adjusted resolution.

Abstract: An augmented reality system includes a light source configured to generate a virtual light beam. The system also includes a light guiding optical element, the light guiding optical element is transparent to a first real-world light beam, wherein the virtual light beam enters the light guiding optical element, propagates through the light guiding optical element by total internal reflection (TIR) and exits the light guiding optical elements. The system also includes a lens disposed adjacent and exterior to the surface of the light guiding optical element. The lens is configured with a gradient tint that transmits less real-world light at a world side top portion of the lens and transmits more real-world light at a world side bottom portion of the lens, wherein rainbow artifacts, generated from inadvertent diffraction of the overhead real-world light by the light guiding optical element, is minimized.
