Stabilizing Mood and Sleep With Blue Blocking Eyewear in Bipolar Disorder
The study investigates whether add-on treatment with eyewear that blocks the short wavelengths of visible light (<500nm) reduces manic symptoms and improves sleep in patients receiving outpatient treatment as usual for bipolar disorder.

When in a hypomanic or manic phase, participants will be randomized to receive add-on treatment with either blue blocking or low filtration eyewear from 18 PM to 8 AM daily for 7 days.

After this initial intervention phase, the eyewear is used daily for 3 months in either antimanic dose (14 hours) or maintenance dose (2 hours before bedtime).
