Dual focus contact lens prototypes ordered by Pentagon

Innovega says the lenses could be released to the public in 2014
The Pentagon has put in an order for prototype contact lenses that give users a much wider field of vision.
The lenses are designed to be paired with compact heads up display (HUD) units - glasses that allow images to be projected onto their lenses.
Much bulkier HUDs are already deployed by the US Army and Air Force to superimpose data about targets and other status updates over users’ views.
The tech could help troops enhance their awareness on the battlefield.
The iOptik system’s developer, Innovega, told the BBC it had signed a contract earlier this week to deliver a fully-functioning prototype to the Pentagon’s research laboratory, Darpa.
The US Department of Defense had previously funded part of the Washington-based firm’s initial engineering work on the project.
“The new contract gives us an immediate opportunity to start prototyping and demonstrating elements of this new system,” Innovega’s chief executive Steve Willey said.
