Tired of the same old glasses? For centuries, spectacles have remained largely unchanged. But now, a revolutionary technology is poised to disrupt the eyewear industry: autofocusing lenses. IXI, a company aiming to modernize glasses, is on the cusp of introducing lenses that could make multifocal glasses a thing of the past.
After unveiling a 22-gram (0.7-ounce) prototype frame, IXI is showcasing working prototypes of its autofocus lenses. These lenses are designed to combat age-related farsightedness, a common condition affecting people over 45. Instead of relying on the traditional multifocal approach, IXI's glasses employ a clever combination of cameraless eye tracking and liquid crystal lenses. These lenses automatically adjust based on the user's focus, seamlessly switching between prescriptions. And the best part? They look just like regular glasses.
So, how does this magic work? The IXI glasses utilize a system of LEDs and photodiodes to track your eye movements. These components are strategically placed around the lenses. They emit invisible infrared light that bounces off your eyes. This allows the system to detect subtle eye movements and how your eyes converge when focusing on something close. This technology requires far less power than camera-based systems, using only 4 milliwatts of power. The glasses track eye movements, blinking, and gaze direction.
Most of the technology, including the memory, sensors, and eye tracker, is housed in the front frame and the arms of the glasses. The prototype uses batteries similar in size to those found in AirPods, and the charging port is integrated into the left arm hinge. A single charge should last a full day. The prototype frames are roughly the same weight as traditional glasses, and the company has refined the design to accommodate different face shapes.
IXI's prototype lenses are made of layers of liquid crystal and a transparent ITO (indium tin oxide) conductive layer. These layers switch almost instantly to create the correct prescription lens. These thin lenses can easily be integrated into existing prescriptions and provide cylindrical correction for astigmatism.
But here's where it gets controversial... Autofocus lenses could potentially eliminate the need for multiple pairs of glasses, such as bifocals and progressives. Even if the glasses run out of power, they would still function as regular glasses with your standard prescription. The sensor technology could also offer insights into other health conditions, such as dry eyes, attentiveness, posture, and neck movement. IXI's technology could potentially adapt prescriptions dynamically, offering stronger corrections as your eyes get fatigued.
IXI is taking the necessary steps to make these glasses a reality. The company has partnered with Swiss lens-maker Optiswiss for manufacturing and plans to launch its first pair sometime next year, positioning them as a high-end luxury glasses option sold through existing opticians.
