An international team of researchers have created the first telescopic contact lens; a contact lens that, when it’s equipped, gives you the power to zoom your vision almost three times. Yes, this is the first ever example of a bionic eye that effectively gives you Superman-like eagle-eye vision.
…the telescopic contact lens has two very distinct regions. The centre of the lens allows light to pass straight through, providing normal vision. The outside edge, however, acts as a telescope capable of magnifying your sight by 2.8x. This is about the same as looking through a 100mm lens on a DSLR. For comparison, a pair of bird-watching binoculars might have a magnification of 15x. The examples shown in the image below give you a good idea of what a 2.8x optical zoom would look like in real life.
The telescopic contact lens, in action
The main breakthrough is that this telescopic contact lens is just 1.17mm thick, allowing it to be comfortably worn. Other attempts at granting telescopic vision have included: a 4.4mm-thick contact lens (too thick for real-world use), telescopic spectacles (cumbersome and ugly), and most recently a telescopic lens implanted into the eye itself. The latter is currently the best option currently available, but it requires surgery and the image quality isn’t excellent — via redwolf.newsvine.com
