Testing blue-blocking glasses to help manic episodes in bipolar disorder

This trial is testing whether blue-blocking glasses—special eyeglasses that filter out blue light from screens and lights—can help reduce manic symptoms in people with bipolar 1 disorder. Researchers believe that blue light exposure in the evening may worsen mania, and blocking it might help calm these symptoms. The study will track whether wearing these glasses for one week during hospitalization makes a measurable difference in how severe manic symptoms are.

People with bipolar 1 disorder experience severe manic episodes that are difficult to treat with medication alone. There is growing evidence that blue light exposure—especially in the evening and night—can affect brain chemicals that control mood and sleep, which may make mania worse. This study aims to see if a simple, non-medication approach like blue-blocking glasses could be a helpful addition to standard treatment.
