Summary

This pilot study tests whether a wearable device that delivers intermittent white light at 60 Hz can safely help people with moderate to severe depression. Thirty adults on stable antidepressant medication will wear the goggles for 30 minutes daily over two weeks. The main goal is to check safety and tolerability, while also looking for any improvement in mood.
