Imagine there is an object far off, which you are unable to see. Well, you don’t have to cover all the distance by foot to see what it is exactly. Simply zoom in your contact lenses! Sounds like something straight out of the fiction? This may soon become reality if the work of some scientists sees the light of day ..

Innovega, the developer of iOptik shared with BBC that it has 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 ..

Steve Willey, the chief executive of Innovega said, “The new contract gives us an immediate opportunity to start prototyping and demonstrating elements of this new system.” ..

To make these lenses work, the wearer has to focus on two things, i.e the information on the lens of the glass and the more distant scene that can be viewed using them. Two filters are used for this purpose ..

“The central part of each lens sends light from the HUD towards the middle of the pupil, while the outer part sends light from the surrounding environment to the pupil’s rim,” reports BBC. Every image reaches the retina at the same time ..

“Normally, for example, with a camera you focus on something distant or something close – but you focus on a particular spot. By wearing our contact lens you automatically have this multi-focus, or dual-focus, and you are doing something that humans don’t usually do,” added Willey ..
