To present a novel passive contact lens design for high-precision eye tracking using moiré patterns.
Key Findings:
The moiré-based lens is entirely passive, requiring no onboard electronics or dedicated light sources.
It can be monitored using standard external cameras under ambient lighting, reducing energy consumption.
The design avoids limitations of previous contact lens trackers that required complex electronics.
Interpretation:
The technology could enable detailed analysis of eye movements relevant to neurological diseases, while being lightweight and scalable for future applications.
Limitations:
Clinical validation and long-term safety are yet to be established.
Real-world integration challenges remain.
Conclusion:
Moiré-based contact lenses represent a promising advancement in low-power eye tracking, potentially transforming ocular monitoring and diagnostics.
