- Lenses can let troops see through 'eyes' of drones flying above
- Can 'layer' target information over view of world
- Contact lenses don't impede fighter's vision
- Equivalent to a 240-inch 3D television from 10 feet
Google wowed the world this week with its Project Glass computer glasses - but the U.S. Army is investing in a technology one step ahead.
The Pentagon has placed an order with Innovega for lenses which focus 3D battlefield information from drones and satellites directly into people's eyeballs.
The tiny 'screens' sit directly on users' eyeballs and work with a pair of lightweight glasses with a built-in translucent screen.
The lenses sit directly on the eyeball, and have been engineered using nanoscale techniques to work as a focusing device that pairs with a pair of hi-tech glasses
