You could approximate this using a standard display if you could dynamically track and respond to focal depth.

That might be harder than getting a functional light field display, though.

Much easier, we have the tech in ophthalmology and adaptive lenses that are used in cellphone cameras.

Out of curiosity, what would the tech stack look like?

What I was picturing was: - LCD display - Patterned IR image projected onto eye - Camera to read IR image on the back of retina, to figure out current focal length of cornea - Realtime chip to adjust LCD display based on focal depth, to simulate light field image.

... The real issue is that response latency would have to be <10ms probably to avoid being disorienting.
