A near-eye lightfield display may be paired with a computer system that automatically updates the rendering viewpoint according to positional and orientational sensor data, such as a [[virtual reality]] system or [[augmented reality]].

Sharp images from out-of-focus display elements are depicted by synthesizing these light fields that correspond to virtual scenes located within the viewer’s natural accommodation range. Lanman and Luebke (2013) mentioned that “conventional displays are intended to emit light isotropically. In contrast, a light field display supports the control of tightly-clustered bundles of light rays, modulating radiance as a function of position and direction across its surface.”<ref name=”2”>Lanman, D. and Luebke, D.

Traditional HMDs only provide a single display plane; without a proper focus cue, the display decouples accommodations from the vergence of the eyes. Since there is a mismatch, the observer has to rely only on the binocular vision to perceive a 3D space. This can lead to visual discomfort, fatique, eye strain, and headaches <ref name=”6”> Stanford Computational Imaging Lab (2015). The Light Field Stereoscope - SIGGGRAPH 2015 [Video].
