(FWIW, that specific set of issues was not related to having a monitor in his peripheral vision, but replacing his eye with the output of a camera that had a slightly different perspective, something that Glass does not attempt.) |

"Using lenses in this way forces one eye to remain focused at some set distance [the screen] while the focus of the other eye shifts according to whatever the wearer is looking at, near or far. Doing this leads to severe eyestrain, which again can be harmful, especially to children."
His solution is to not use a lens, but a pinhole:
"My pinhole aremac is the reverse of a pinhole camera: It ensures that you see a sharp image through the display, no matter how you focus your eyes. This aremac is more complicated than a barrier with a pinhole, though. It requires a laser light source and a spatial light modulator, similar to what’s found inside many digital projectors. With it, you can focus both eyes normally while using one eye to look through the mediated-vision system, thus avoiding eyestrain."
