I think the most prominent attempt at see-through AR was the Microsoft HoloLens. But if you've actually tried the HoloLens, the Field of View is atrociously, tragically small. The first HoloLens had a field of view of 30°*17.5°. The second HoloLens improved to 43°*29°, but it's still best described as "cramped." Couple that with almost all of the compute budget for the device going into vision processing and having very little compute left for actually running apps (the first HoloLens having a 1Ghz Intel Atom from 2015, the second a superior... Snapdragon 850).
The other problem, of course, is that nothing can be truly solidly-colored. Everything has some opacity - which, combined with the FOV issue, is why HoloLens was never marketed as having anything to do with VR.
The vision processing was done with a separate SoC. Your applications were not contending for compute time with the vision processing. That's just how anemic the CPU was.
