# Camera-Readable Smart Lenses XPANCEO Develops Contact Lenses That Track Eye Movement Without Power By Mursal Rahman | Published 2026-04-13 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/xpanceo References: [digitaltrends](https://www.digitaltrends.com/wearables/next-gen-contact-lenses-promise-futuristic-eye-tracking-without-pricey-gear/) & [techxplore](https://techxplore.com/news/2026-04-deep-tech-company-high-precision.html)  XPANCEO is advancing [wearable technology](https://www.trendhunter.com/trends/wearable-ecosystem) with contact lenses that enable passive eye tracking using standard cameras. Unlike conventional systems that rely on infrared illumination and power-intensive sensors, these lenses use microscopic optical patterns to generate moiré effects that shift with eye movement. This allows precise gaze detection without batteries or embedded electronics, reducing hardware complexity while maintaining high accuracy. This approach expands the potential for seamless interaction across devices, including smartphones, vehicles, and [head-mounted systems](https://www.trendhunter.com/trends/eye-tracking-device), where built-in cameras can interpret eye movement in real time. For healthcare, the system introduces new possibilities for monitoring subtle eye behaviors linked to neurological conditions, supporting earlier detection and ongoing assessment. In industrial and transportation settings, it could enhance safety by identifying fatigue or cognitive impairment. As a result, brands and manufacturers may explore more scalable, low-power eye-tracking solutions that integrate effortlessly into existing ecosystems.
