Summary

This study tests whether wearing light therapy glasses for one hour each morning can reduce obsessive-compulsive disorder (OCD) symptoms in young adults (ages 18–35) who go to bed at 1 a.m. or later. Participants wear the glasses daily for five weeks, track their sleep, and complete OCD symptom questionnaires. The goal is to see if advancing the body's internal clock with morning light can ease repetitive thoughts and behaviors.
