A '''Near-eye lightfield display''' (NELFD) is a type of [[Near-eye display]] (NED), often implemented in a [[Head-mounted display]] (HMD), designed to reproduce a [[lightfield]]—the complete set of light rays filling a region of space—rather than just a single flat [[image]] for the viewer.~~<ref name="VRARWiki">[Near-eye light field display - VR AR & XR Wiki](https://xinreality.com/wiki/Near-eye_light_field_display)</ref>~~ By emitting light rays with potentially correct spatial *and* angular distribution, a NELFD allows the viewer’s [[eye]]s to engage natural [[Vergence|vergence]] *and* [[Accommodation (visual)|accommodation]] (focusing) responses simultaneously.
