Who wouldn’t want to have vision like the Terminator? The possibility is coming into sight thanks to the development of a contact lens that would allow wearers to zoom in on points of interest.
Just over a millimetre thick, the telescopic lens works by having a central unmagnified optical path that is surrounded by a ring of optics that magnify the view 2.8 times. Liquid crystal shutters then block one or the other of these optical paths – allowing the user to switch between regular and magnified vision. Learn more here.
