Most clear-lens blue light glasses filter only up to 420nm — a range primarily emitted by sunlight, not screens or LEDs. The wavelengths that actually disrupt sleep, hormones, and eye health from modern devices sit higher, in the 450–530nm range. Clear lenses don't touch them.
Ra Optics lenses are scientifically engineered to filter exactly that range — developed in direct collaboration with Dr. Alexander Wunsch, M.D., Ph.D., the world's pre-eminent expert in photobiology. Dr. Wunsch's life's work covers how light affects living systems — the benefits of natural light, photo-biomodulation, the risks of artificial light, and the psychological and physiological effects of color.
Every lens is precision-calibrated to maximize protection while preserving visual clarity and natural color rendering.

The philosophy: Maximal protection. Optimal experience. Not more filtering than necessary — precisely the right filtering, for the right use case.

Designed for the evening transition.
When to wear: From 2–3 hours before sleep, until bed.
How they work: Sunset lenses block 100% of blue light and key wavelengths of green light — eliminating the artificial "daytime" signal that suppresses melatonin and prevents the body's natural shift into repair and recovery mode. The amber tint is functional, not cosmetic. It's a direct result of the required filtration.
Key benefits:
What to communicate: Your audience has felt this — wired at midnight, eyes heavy, unable to wind down after a screen-heavy evening. That's biology, not willpower. Sunset lenses remove the signal that keeps the body in daytime mode. That's the story worth telling.

Pair with your environment. Sunset lenses work best in a low-light setting. Overhead LEDs continue to send disruptive signals even through tinted lenses. Combining Sunset lenses with Lumios compounds the results significantly.
