I am trying to make the cheapest glasses, and using as little power as I can, to help out Africa and India.
I am kinda stuck because I am dealing with schizophrenia, but the proof-of-concept is working. You can't stream RGB videos, but the key is that you can stream 1-bit videos, using a dithering algorithm.
Using 2 displays SSD1306 is a bit clunky (you need soldering) but you can use a SSD1306 + SSD1351, for example. One as I2C wiring, the other with SPI wiring.
For VR, you can easily stream information from a server. I manage 100 vertices at any given time. Check the code, it works, or if it doesn't, then do it your way.
I am out of money and out of time, so I'm hoping other people will organize and make it happen. I guess I am dreaming. I'll do it myself just it should take a few months.
