HUD in a contact lens

That research dated from January 2008 definitely shows the path to where we’re heading with VR-WEAR,“Contact lenses with circuits, lights a possible platform for superhuman vision”

A few excerpts from the article:

Engineers at the University of Washington have for the first time used manufacturing techniques at microscopic scales to combine a flexible, biologically safe contact lens with an imprinted electronic circuit and lights.

The prototype device contains an electric circuit as well as red light-emitting diodes for a display, though it does not yet light up. The lenses were tested on rabbits for up to 20 minutes and the animals showed no adverse effects.

This is exactly the first step to “wearable computing” as described in Vernor Vinge’s “Rainbows end”
