* '''[[Meta Reality Labs Research]] (formerly Facebook Reality Labs) Half-Dome Series (2018-2020):''' A series of research prototypes exploring varifocal displays. Half-Dome 1 used mechanical actuation; later versions like Half-Dome 3 used a stack of liquid crystal lenses to achieve 64 discrete focal planes electronically, combined with [[eye tracking]] and a wide FoV (~140°)<ref name="AbrashBlog2019">Abrash, M.

* '''CREAL (2020 onwards):''' A company developing compact lightfield display engines for AR, often using time-multiplexed micro-LED projection or scanning combined with holographic combiners. Prototypes aim for continuous focus (e.g., 0.15m to infinity) within a ~50-60° FoV in a glasses-like form factor<ref name="CrealWebsite">CREAL (n.d.). Technology.
