If I understand this correctly, this is a light-field display.

The implications are bigger than vision correction - LF display can reconstruct actual 3d images, as opposed to the stereo images being marketed as "3d" today. Stereo displays give two different pictures to two different eyes, but the don't provide perspective shift (the picture doesn't change when you move your head left and right), and they don't provide different focal planes (your eyes focus on the screen plane regardless of how far the object is supposed to be, creating a dissonance between the distance inferred from the angle between the eyes and the focusing distance).

Yup, I wonder if this technology could be used to improve head-mounted displays, to be able to focus on different parts of the virtual scene, not just being always focused on infinity (probably together with high-precision eye-tracking to figure out depth where you try to look at).
It can and will in relatively short order: https://www.youtube.com/watch?v=deI1IzbveEQ

Douglas Lanman, the researcher behind this technology work at Nvidia was hired a few months ago by Oculus VR.

Magic Leap got $50M first round funding to do just that:
