Ask HN: Recommend display glasses for computing while walking

Is there anything out there at all? I want something like no-strength glasses with high-definition display, monochrome is acceptable. Preferably see through, so I can walk, but also read the text. They don't need to have bulky cameras or other sensors. I just want some glasses to display the terminal from the raspberry pi in my backpack, so I can walk around and program or write with a chorded keyboard.
