I have a friend who is almost blind. Nothing wrong with his eyes. It is his visual cortex that has the problem. Can't be corrected with lenses.

I think this type of technology will be of great use for people that have this kind of genetic deficiency.

As an example. Currently my friend uses an iPhone to take a picture of a menu, holds the display a few inches form his eyes and zooms in on the picture to read the menu.

I think he could use these glasses to stream zoomed in video and actually see what is going on around him.
