  • Description
    Evening | Indoors & Outdoors

    Yogananda Sunset Lenses are for evening wind-down and deep sleep.

    • Relax Naturally
    • Get Your Best Sleep
    • Boost Melatonin
  • Benefits
    • Align Circadian Rhythm: Reset your body clock
    • Boost Melatonin: Natural hormone production
    • Fall Asleep Faster: Drift off in minutes
    • Sleep Deeply: More restorative REM
    • Cellular Repair: Nightly regeneration activated
    • Wake Rejuvenated: Morning energy restored
  • How It Works

    Light That Blocks Rest

    Evening exposure to LEDs, screens, and indoor lighting:

    • Suppresses melatonin by up to 90%
    • Keeps cortisol elevated when it should drop
    • Disrupts cellular repair processes
    • Creates dependency on sleep aids
    • Accelerates aging and disease risk

    Light That Supports Rest

    Ra Optics Sunset Lenses block 100% of melatonin-disrupting wavelengths, allowing your body to:

    • Wind down naturally without alcohol or sleep aids
    • Produce melatonin as evolution intended
    • Activate repair mode for cellular regeneration
    • Sleep deeper with more REM cycles
    • Wake refreshed with balanced hormones
    • Age slower through proper nightly recovery
  • The Science

    At night, light from screens and LEDs can keep your brain in "day mode," making it harder to slow down.

    Sunset Lenses filter 380-540 nm, the wavelengths that send that daytime signal. Put them on after sunset, and your world instantly feels calmer. Your mind settles, and your body can shift into its natural nighttime rhythm.

    Effortless, precise, and made to help you feel the difference.

    With Dr. Wunsch, we have developed a set of superior, proprietary standards for the quality and efficacy of blue light protection eyewear: the Ra Superlative ™ Standard.
    These include:

    • Wavelength-Specific Blue Light Protection: we utilize wavelength-specific LEDs to test for optimal blue light protection in the primary ranges of biological concern.
    • Short-and Long-Term Stress Tests utilizing high-intensity blue and full-spectrum LED light sources directly on the lens to ensure that Ra Lenses can endure extreme conditions beyond any normal exposure-and that their protection will endure for a lifetime.
    • Careful Measurements of Color Rendering to ensure optimal color perception, usability, and visual comfort-balancing maximum protection with a superior wearer experience.
    • Extremely Calculated Selection of Lens Hue-drawing from Dr. Wunsch's 35+ years of clinical application of color therapy to select hues which support and enhance our lenses' desired physiological and psychological effects.
  • FAQs

    Q: When should I wear Sunset lenses?

    A: Sunset Lenses are designed to be worn from sunset until bedtime, or at least three hours before sleep, for optimal results. They support your body's natural circadian rhythm, the internal "clock" that synchronizes biological functions with the day-night cycle.

    Historically, the setting sun triggered melatonin production, slowing metabolism and supporting cellular repair. Modern artificial light disrupts this process, signaling your brain that it's still daytime, reducing melatonin, making it harder to fall asleep, and limiting restorative repair.

    Chronic disruption can contribute to fatigue and long-term health risks.
    By wearing Sunset Lenses as directed, you help your body wind down naturally, fall asleep more easily, sleep more deeply, and wake up feeling refreshed and energized.

    Q: Will Sunset Lenses help me sleep better? Will they reduce eye strain?

    A: Our Sunset Lenses are designed to filter the blue light wavelengths that stimulate the brain and body in the evening. By removing this sleep-disrupting light, Sunset helps the nervous system relax, supports natural melatonin release, and makes it easier to fall asleep and stay asleep.

    By significantly reducing high-energy blue light exposure at night, Sunset also eases visual stress from screens and artificial lighting, allowing the eyes to recover during their natural repair window.

    For evening screen use, indoor lighting, or the final hours before bed, Sunset is the optimal choice for protecting sleep, recovery, and next-day energy.

    Q: Can I wear them during the day?

    A: Sunset Lenses can be worn during the day, but their high level of tiltration reduces light and color perception. This may make color-sensitive tasks more challenging and can cause drowsiness when alertness is required.

    Recommended daytime use for Sunset Lenses:

    • In environments with intense artificial lighting, such as hospitals or offices.
    • Outdoors under strong sunlight, providing short-wavelength protection while retaining longer, near-infrared benefits.

    Sunset Lenses were originally designed to enhance evening relaxation and sleep quality. Daylight Lenses were developed for daytime use to filter blue light from screens and artificial lighting, and can also serve as a lighter evening option for those who prefer less tint.

    Evening scenarios for Daylight Lenses:

    • Late meals, when color perception is important.
    • Ideal for social settings where natural color clarity and light protection are needed.
    • Nighttime driving.
    • Gradual transition to Sunset Lenses.

    For optimal blue-light management, use Daylight Lenses during the day and Sunset Lenses at night—a complete system supporting both alertness and restorative rest.

    Q: Are these lenses too dark? Will I still see clearly?

    A: Sunset Lenses are designed to simulate natural post-sunset lighting by significantly reducing brightness-blocking 77% of light and allowing only 23% to pass through. This reduction supports circadian rhythm alignment but can influence vision in low-light conditions.

    Natural Vision Changes in Low Light: In dim environments, the eyes rely more on rod cells, which are highly light-sensitive but provide less sharp central vision, leading to slightly blurrier perception.

    Pupil Dilation and Depth of Focus: As ambient light decreases, pupils widen, reducing depth of field and making it more challenging to maintain sharp focus-particularly with lenses that reduce brightness.

    Reading Glasses Option: For close-up tasks, consider Sunset Lenses with built-in magnification. These maintain circadian benefits while enhancing clarity for reading.

    Q: What wavelengths do your Sunset lenses block?

    A: They exhibit a complete cut-off around 500 nm, with less than 5% transmission until approximately 550 nm. Allowing a small amount of light through this range enhances color perception and overall comfort, without transmitting enough short-wavelength light to disrupt sleep or circadian rhythm- the peak sensitivity of which is near 479 nm (the melanopsin absorption spectrum).
