This company develops MiEye, a wearable light sensor designed specifically for circadian rhythm research studies. The device accurately measures light exposure by modeling its impact on the circadian clock, differentiating it from standard visual light perception. Researchers use this data to understand real-world light patterns and their effect on human photoreceptors.

Problem
Research indicates that unhealthy light behaviors can contribute to chronic diseases, yet the health effects of light exposure often occur non-consciously. Existing methods for measuring light exposure may not accurately capture the specific impact on the human circadian clock. This makes it difficult for researchers to fully understand and address the effects of real-world light patterns on circadian rhythms and overall health.
Solution
Circadian Health Innovations offers MiEye, a wearable light sensor designed to measure light exposure as perceived by the circadian clock, capturing data on all photoreceptor responses to real-world lighting conditions. The device models the impact of light on the circadian clock, providing insights into personal circadian rhythms and healthier light behaviors. MiEye is optimized for multi-day field studies, enabling researchers to collect comprehensive data on light exposure patterns and their effects. The device incorporates an on-board accelerometer to distinguish wear versus non-wear times, improving the accuracy of light data analysis.
Target Audience
The primary users are researchers studying circadian rhythms and the impact of light exposure on health.
