Objective:

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.
