Summary
This study tested smart glasses that control how much blue light reaches your eyes, giving more blue light during the day and less at night. Researchers wanted to see if wearing these glasses could improve depression and sleep in 96 adults. The glasses are a non-drug approach that might help people who spend little time outdoors.
