Summary
This study aims to create an objective way to diagnose and monitor light sensitivity by measuring facial expressions, pupil reactions, and nerve responses to light. Researchers will compare 120 people with and without light sensitivity (due to traumatic brain injury or migraine) to find reliable biological markers. The goal is to replace subjective patient reports with a simple, accurate test.
