What this trial studies

This study investigates the non-visual effects of light on various health conditions, including sleep disorders, neurological, psychiatric, and ophthalmological pathologies. It aims to understand how light influences behavior, mood, cognition, and sleep through specific light exposures. By examining these effects, the study seeks to establish new therapeutic applications for patients suffering from these conditions. Participants will be grouped based on their specific health issues or as healthy controls to assess the varying impacts of light exposure.
