IXI’s autofocusing lenses are almost ready to replace multifocal glasses

IXI has announced that its prototype autofocus glasses are nearing commercial readiness, with plans to launch next year. The glasses use liquid crystal lenses that automatically adjust focus, potentially replacing multifocal and bifocal glasses for age-related farsightedness. This development could significantly impact the eyewear market by offering a seamless, adaptive solution for millions of users.

At CES, IXI showcased working prototypes of their lightweight, stylish glasses equipped with liquid crystal lenses that switch focus automatically based on eye movement. The glasses incorporate eye-tracking technology using infrared LEDs and photodiodes located at the frame edges, consuming only 4 milliwatts of power, and can be charged via a small port integrated into the hinge. The lenses are extremely thin, layered with liquid crystal and a transparent conductive layer, allowing near-instant focus adjustment.

The technology can provide prescriptions for farsightedness and astigmatism, and even offers potential health insights by tracking blinking, gaze, posture, and neck movement. The system’s sensors can detect changes in blink rate associated with focus, fatigue, or anxiety, with data accessible via a companion app. IXI intends to partner with Swiss lens manufacturer Optiswiss for production, aiming to position the product as a high-end luxury option sold through opticians. The company still needs medical certifications before market entry, but plans to launch in the coming year.

Why It Matters

This innovation could transform the eyewear industry by eliminating the need for multiple pairs of glasses, such as bifocals or progressives. It offers a seamless, adaptive solution for age-related vision issues, potentially improving quality of life for millions of users. Additionally, the integrated health tracking features could open new avenues in health monitoring and personalized vision correction.

Background

Traditional multifocal glasses, introduced in the 1950s, have remained largely unchanged. Recent advancements have focused on smartglasses and digital solutions, but none have achieved widespread commercial success. IXI’s approach represents a significant technological leap, combining eye-tracking with liquid crystal lenses for real-time focus adjustment. The company announced prototypes at CES, with plans to commercialize after obtaining necessary medical approvals, aiming for a launch in 2024.

“Our glasses use eye tracking and liquid crystal lenses to automatically adjust focus, offering a seamless experience that could replace multiple pairs of glasses.”

— Niko Eiden, CEO of IXI

“IXI’s prototype glasses are lightweight, look like normal spectacles, and could soon be available commercially, representing a major step forward in vision correction technology.”

What Remains Unclear

It is not yet clear when IXI will obtain all necessary medical certifications or the final retail pricing. The long-term durability and user acceptance of the liquid crystal lenses in everyday conditions are still to be proven. Additionally, how the technology will adapt to different prescriptions and face shapes remains under development.

What’s Next

Next steps include completing medical certification processes, finalizing manufacturing partnerships, and conducting broader user testing. The company aims to launch the first commercial product within the next 12 months, with further updates on availability and pricing expected as development progresses.

Key Questions

When will IXI’s autofocus glasses be available for purchase?

IXI plans to launch its first product sometime next year after completing necessary certifications and finalizing manufacturing arrangements.

Will the glasses work if the battery runs out?

Yes, the glasses will still function as traditional prescription glasses without autofocus capabilities if the battery is depleted.

Can these glasses correct for other vision issues besides farsightedness?

The current prototypes mainly target age-related farsightedness, but the liquid crystal lenses can also provide cylindrical correction for astigmatism. Future versions may include broader prescription adjustments.

How do the glasses track eye movement without a camera?

They use infrared LEDs and photodiodes embedded in the frame edges to detect eye movement, blinking, and gaze direction with low power consumption.

Will these glasses be expensive?

IXI intends to position the product as a high-end luxury item sold through opticians, so pricing details are still to be announced but are expected to reflect premium positioning.
