About this trial

Many people suffer from migraine headaches, some more so than others and a common trigger/complaint is light sensitivity, or photophobia1. Some will go to great lengths to avoid light: a dark room with sunglasses on and blankets over the windows, often missing work/school/social activities, etc. Several ocular conditions are accompanied by photophobia, ranging from mild to debilitating.
