Two polarizers with a layer of liquid crystal between them. Cell by cell, the liquid crystal can turn the room light so the second polarizer stops it, darkening any part of your view: true black behind the picture, or the whole lens dark for virtual reality. The polarizers also keep the display light inside the lens, so no one around you sees your screen.
Transparent micro-OLED pixels switched by 2D TMD transistors, across the whole lens. Their light is polarized orthogonal to the room light the polarizers let in.
A liquid crystal layer that is programmed into a microlens array, aiming each pixel's light into your eye from its own direction, so each part of the picture sits at its own depth. Room light passes unchanged.
The same layer turned 90°, acting only on room light, in place of prescription lenses. One programmable layer for any prescription. More accurate and adaptive than your geometrical lens glasses.
