Liora is a wearable light therapy system designed for night shift workers. The complete solution — smart glasses, biometric ring, and mobile app — adapts to unconventional sleep-wake cycles and improves sleep quality through personalized light exposure management.
Liora integrates three core elements: light therapy glasses that emit specific wavelengths, a biometric ring that collects physiological data, and a mobile app that syncs this data with the user’s work and rest schedules. The system then delivers real-time recommendations to optimize light exposure and support circadian alignment.
Liora is based on light therapy principles, using targeted wavelengths to regulate the body’s internal clock. Exposure to blue light helps maintain alertness, while in the evening, the interface shifts automatically to red light to avoid disrupting melatonin production — encouraging quicker sleep onset and deeper rest.
Unlike conventional home-use or clinical light therapy equipment, Liora is designed for portability and daily wear. Both the glasses and ring are discreet and ergonomic, allowing users to continue therapy while commuting, working, or winding down — whenever their schedules demand it.
The biometric ring continuously monitors vital indicators such as heart rate, body temperature, and sleep phases. Combined with the user’s inputted shift schedule, the app delivers a tailored light therapy program, adjusting timing and light type to align with the user’s unique circadian rhythm.
Liora is the brainchild of South Korean designers Byun Jeonghun, Song Hohyun, and Park Jisu. The concept won a Red Dot: Next Gen Award in the Healthcare category for its thoughtful blend of design, portability, and scientific rigor in the field of wearable light therapy.
Because Liora addresses a critical yet often overlooked health challenge: sleep disruption in irregular work schedules. By combining portable design with biometric data and therapeutic light, it represents a new wave of wellness tools tailored to real-world circadian needs.
