I believe they will fade away or evolved into more of a VR device (gaming). I have glasses but they are not something I enjoy wearing. I buy glasses that are aesthetically pleasing and I cannot imagine a tech company being able to design something that is somewhat fashionable. I personally feel some things should be unconnected, every day glasses being one of them. I love tech, but my smartphone is all I really need connected. However, if x-ray vision comes to glasses, I'd buy a pair. :)
