−Near-eye light field displays introduce a [[light field]]-based approach to [[near-eye display]]s (NED)s. This enables [[display headset]]s that can generate accurate natural 3D visuals with proper human [[accommodation]], [[convergence]], and [[binocular disparity]].
A '''near-eye lightfield display''' is a kind of [[light field display]] that can be viewed near to the eye. It can be part of a [[display headset]].

A light field display, depending on the type, can be continuously viewed close to the eye and far away. An example of such type of display is a [[monocle]].
