The eye is not focusing on that depth. The light coming out of the lens or LCD would be collimated / diffracted to form an image on the retina that appears to originate from a specific distance (or in this case, many different distances, multiplexed together).
Just like with Google Glass, where the image appears to be at a distance and your eyes do not focus on the actual screen.
