How would Avegant's Light field tech be working?

I am wondering how Avegant would have its Light Field Tech developed with their retinal display technology (using low powered DLP projectors to project to out to your eye directly). Its really an interesting idea of using two DLP projectors to project images directly to the eye with the Glyph. I am wondering whether with the Light field tech, they have these projectors projecting maybe we can say 10 different frames at 120Hz which could be in different focal planes, but the human eye only allows us to see one of those planes and when we change focus, one of the other frame which is already there gets focused on. What are your thoughts experts on this?
