About This

• Benefits: Wear Sunset Lenses between sunset and bedtime. Experience newfound relaxation in the evening, fall asleep more easily, sleep more deeply, and wake up with more energy. Customers who wear sleep tracking devices consistently report significant improvements in their sleep scores when wearing Ra Optics.
• The Risks of Blue Light at Night: Exposure to blue light at night (from cell phones, TV’s, computers, and light bulbs) tricks the brain into thinking it’s still daytime, preventing the production of the essential hormone melatonin, which is critical for optimal sleep, cellular repair, and overall health.
• Designed for Protection and Results: Sunset Lenses were designed with leading scientific experts and use advanced, proprietary pigment technology to block blue light’s disruptive wavelengths. This allows the brain to properly release melatonin. Increased melatonin production leads to natural evening relaxation, falling asleep more easily, sleeping more deeply, and waking up more energized. Sunset Lenses’ unique color comes from maximum filtration of blue and green light wavelengths.
