The Ryva Daily Set

Our night lenses are designed to block short-wavelength light—primarily in the blue and green spectrum—to reduce light stress, protect circadian rhythm, and help relax the nervous system. They are a physiological tool to prepare for sleep and promote recovery.

By filtering out wavelengths below 500 nm (especially the 460-480 nm range), the lens helps preserve melatonin production and reduces overstimulation, two crucial factors for falling asleep faster and sleeping more deeply.

Of course. They are designed for nights when we spend a lot of time in front of screens; they filter artificial light from phones, laptops, and televisions to help your brain disconnect and your body prepare for rest.

The brain interprets short wavelengths (blue/green) as daylight. These suppress melatonin and cause alertness, keeping the nervous system active when it should be resting.

We use CR-39, a high-fidelity optical resin originally developed for aerospace use. It offers excellent clarity, minimal chromatic distortion, and high scratch resistance, ideal for precision in low-light conditions.

For best results, start using them 1 to 3 hours before your planned bedtime. This aligns with your natural melatonin curve and signals your body to biologically relax, not just mentally.

Ryva lenses reduce neuronal activation at the end of the day by decreasing light input and have been linked to an increase in Late Positive Potential (LPP), a brain wave associated with emotional regulation and calming of the nervous system.

Not only do we block light, but we design optical tools for sensory alignment. Ryva is built on circadian biology, neurological impact, and material integrity. It offers laboratory functionality in a wearable format, with an aesthetic that adapts to your system.

We process our orders within 24-48 hours of receiving them. Delivery times vary by destination:
