It’s not only cameras that are coming to contact lenses. UCSD scientists have developed a zoom contact lens that changes focal length by blinking. Soon enough, it seems the best camera may not be the one that’s with you. It may be the one that’s in you, or at least on you. Sony imagines a world where our devices see exactly what we do. Samsung is working on in eye displays, and other health applications and monitoring sensors are being worked into contact lenses. The latest is a wearable zoom lens. The Zoom Contact Lens The latest innovation in eye gadgetry comes from scientists at the University of Southern California San Diego. They have developed a biomimetic soft zoom contact lens that changes focal length when triggered by tiny electrical signals caused when we blink. By blinking twice, the new lens made from electro-active polymer films can instantly change shape. They are working on making the new lenses sensitive enough to detect and react to very slight signals created on the surface of the eye. The researchers wrote: “Because of the use of soft materials, the relative change of focal length of the lens could be as large as 32 percent through deformation. Due to the fast response of [dielectric elastomer films], the movements of the eyes and the soft lens could be easily synchronized.” Right now the technology is too large to wear in the eye and requires the user to wear electrodes on their face but with further...
