IWLS for Major Depressive Disorder: An Open-Label Study of Safety, Tolerability, and Efficacy

A wearable device developed by SyntropicMedical (Austria) delivers intermittent white light at 60 Hz using LED strips embedded in safety goggles. The light is diffused (approximately 700 lux) and projected tangentially to the participant's eyes. Participants will undergo 10 daily sessions (30 minutes each) over a two-week period. The intervention aims to evaluate the safety, tolerability, and potential antidepressant effects of 60 Hz visual stimulation in individuals with moderate to severe Major Depressive Disorder.
