Understanding how lighting affects eye movement and pupil size
Characterization of Eye Movement Behaviour and Pupil Size Through Eye-tracking in Natural Outdoor and Indoor Scenes
This study tests how different indoor and outdoor lighting affects how our eyes move and how big our pupils get, and it's for anyone interested in understanding eye behavior.

What this trial studies
This study investigates the impact of different indoor and outdoor lighting conditions on eye movement behavior and pupil size. Participants will undergo six eye tracking sessions, split across two appointments, where they will view various scenes while adapting to the lighting. The study aims to reveal differences in eye movements and pupil responses between indoor and outdoor environments, utilizing advanced eye tracking technology. Each participant will spend a total of 24 minutes being tracked over the course of the study, which will take approximately 2-3 hours to complete.
Who should consider this trial
Good fit: Ideal candidates are individuals with normal or corrected-to-normal vision who do not have any ocular impairments or psychiatric disorders.
Not a fit: Patients with previous eye surgeries, significant ocular impairments, or those on medications affecting photosensitivity may not benefit from this study.
Why it matters
Potential benefit: If successful, this research could lead to better understanding and management of light sensitivity in patients.
How similar studies have performed: While studies on eye movement and lighting exist, this specific approach focusing on natural scenes and detailed lighting measurements is relatively novel.
