Abstract
This disclosure pertains to a system configured to control light exposure for circadian phase management and/or light deficient disorders of a subject. The system comprises a user interface, physiological sensors configured to generate output signals conveying physiological data of the subject, and a light control valve configured to block or reduce blue light ambient radiation reaching eyes of the subject. Processors are in communication with the user interface, the physiological sensors, the light control valve, and radiation generators. The processors cause the system to receive physiological goals of the subject, determine a light control plan based on the physiological goals, the physiological data, environmental data, and time data. The system operates the light control valve to block or reduce blue light ambient radiation based on the light control plan, and generate, using the one or more radiation generators, therapeutic light radiation based on the light control plan.
