    Abstract: A system configured for providing views of virtual content in an augmented reality environment may comprise one or more of a first display, a second display, an optical element, one or more processors, and/or other components. The first display and second display may be separated by a separation distance. The first display and second display may be arranged such that rays of light emitted from pixels of the first display may travel through the second display, then reflect off the optical element and into a user's eyes. A three-dimensional light field perceived with a user's field-of-view may be generated. Distances of the first display and/or second display to the optical element may impact a perceived range of the three-dimensional light field. The separation distance may impact a perceived depth of the three-dimensional light field and/or a resolution of virtual content perceived with the three-dimensional light field.
