Dual-focus contact lens prototypes ordered by Pentagon

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 head-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.
