If we combine wearable display and scene camera with focusing/zoom capability, we could see what I want to see.
-When old farsighted people read newspaper, she need to wear a reading glass.
-WHen I became nearsighted, I cannot enjoy seeing stars at night.
-When I find a bird in a forest, I want to see it closely. Camera with zoom lens can help but I don’t carry it always.
Camara industry has some technologies for zooming/focusing. Werable display is appearing. Thier combination could be an enhanced human vision system.
