A recent study in Advanced Functional Materials reveals an innovative approach to eye tracking using passive contact lenses embedded with microscopic moiré patterns. This technology exploits optical principles to produce macroscopic moiré fringes, allowing precise eye tracking without the need for onboard electronics or infrared lighting. The design significantly lowers energy consumption, achieves angular precision to approximately 0.28°, and is lightweight, promising advancements in neurological diagnostics and multifunctional lenses. However, issues related to clinical validation and safety must be addressed.
