The big step up is that you don't need to take these glasses out of your pocket every time you want to use them. Phones can't really serve as an "extension of the self" because you don't walk around with them in your hand all the time.

Using "always on" eye-devices would allow them to become second nature. Name/face/voice association would be automatic, looking up a word definition would be accessing slow memory instead of an annoying context-switch. A lot of the difference is not in that you can do something with these glasses, it's that you will.
