| Research Abstract |
The effects of bright light exposure in patients were investigated. 8001x bright light exposure was performed for 3 weeks in the light therapy room. Clinical ratings of sleep-wakefulness improved in eight patients. The score of difficulty in falling sleep and drowsiness in the morning declined during the light exposure. The score of drowsiness in the afternoon decreased during the post light exposure. Post-exposure ocular disorders were not found.
