IXI Autofocus Glasses Adjust Vision Live

The Last Thing About Glasses That Never Changed

Smartphones replaced cameras, maps, and alarm clocks. Hearing aids evolved into near-invisible devices. But the glasses worn by roughly 2.2 billion people have remained largely unchanged — in many ways, over a century old with little modern technology. This observation comes from Niko Eiden, CEO of IXI and co-founder of Varjo, a company known for advanced augmented reality systems. After working on cutting-edge visual technologies, he noticed a clear gap in everyday eyewear.

The result is IXI Adaptive Eyewear — glasses that track eye movement in real time and adjust focus automatically, similar to a camera lens, but continuously and without user input.

Why Bifocals and Progressives Fall Short

The issue IXI addresses affects most people over 45 and is known as presbyopia, an age-related difficulty in focusing on nearby objects. This condition often leads to using multiple pairs of glasses or relying on bifocals and progressive lenses.

Traditional solutions require users to look through specific zones of the lens to see clearly at different distances. While practical, this approach demands adaptation and can cause discomfort. Clinical research involving around 360 participants across several countries found that both conventional and existing smart eyewear require compromises in optical ergonomics, often leading to strain in the eyes, neck, and posture.

IXI removes this limitation by eliminating fixed zones entirely. Instead of the user adjusting their gaze, the lens adjusts dynamically to where the user is already looking.

How the Technology Works

Eye Tracking Without a Camera

IXI glasses track eye movement using LEDs and photodiodes positioned around the frame. These components emit invisible infrared light that reflects off the eyes, allowing the system to detect subtle movements and how the eyes converge when focusing on nearby objects.

Unlike camera-based tracking, IXI uses an analog infrared method that avoids heavy data processing and reduces power use. The system tracks gaze direction, eye movement, and blinking using about 4 milliwatts — similar to a digital watch in standby mode.

Liquid Crystal Lenses

Once the system determines the focal point, it adjusts the lenses. Instead of fixed optics, IXI uses liquid crystal lenses that dynamically change how light is directed toward the eye.

This adjustment happens within milliseconds, making transitions unnoticeable and keeping vision consistently sharp. During setup, each pair is calibrated through the IXI app to match the user’s prescription.

The Hardware Hiding in Plain Sight

All electronic components are integrated into the frame and arms near the hinges. The charging port is placed inside the hinge, maintaining a clean exterior.

The frame weighs about 22 grams, lighter than most reading glasses and significantly lighter than current smart eyewear. The battery lasts a full day and charges overnight. If the battery runs out, the glasses continue functioning as standard prescription lenses, with autofocus temporarily unavailable.

The design remains visually similar to traditional eyewear, with square and round frame options.
