Geometric Lightguide for Near-eye Light Field Display

Optics Express, 2023
Most near-eye displays with one fixed focal plane suffer from the vergence–accommodation conflict and cause visual discomfort to users. In contrast, light field displays can provide natural and comfortable 3D visual sensation to users without the conflict.

Calibrating, rendering and evaluating the head mounted light field display [PDF]

, 2019
There are several benefits of using a light field display over a traditional HMD; in particular the light field can avoid the vergence-accommodation conflict and can also correct for near- and farsightedness.
