"While wave upon wave of smartglasses and face-based wearables crash on the shores of CES, traditional glasses really haven't changed much over the hundreds of years we've been using them. The last innovation, arguably, was progressive multifocals that blended near and farsighted lenses - and that was back in the 1950s. It makes sense that autofocusing glasses maker IXI thinks it's time to modernize glasses."
"IXI's glasses are designed for age-related farsightedness, a condition that affects many, if not most people over 45. They combine cameraless eye tracking with liquid crystal lenses that automatically activate when the glasses detect the user's focus shifting. This means that, instead of having two separate prescriptions, as in multifocal or bifocal lenses, IXI's lenses automatically switch between each prescription. Crucially - like most modern smartglasses - the frames themselves are lightweight and look like just another pair of normal glasses."
IXI demonstrated working autofocus lens prototypes and a 22-gram prototype frame aimed at modernizing glasses for age-related farsightedness. The glasses use cameraless eye tracking combined with liquid crystal lenses that automatically activate when focus shifts, enabling automatic switching between prescriptions instead of multifocal designs. The frames remain lightweight and resemble regular glasses. Eye tracking is achieved with LEDs and photodiodes placed around the lens edges; invisible infrared light is bounced off the eyes and reflections are measured to detect subtle eye movements and convergence when focusing on close objects. The infrared approach uses far less power than camera-based systems.
