Flow Evening Lens
Protects Circadian Rhythm
Calms Eye + Mind Strain
Fall Asleep Faster
100% Blue Light BlockingDescription
Flow brings a refined edge to a bolder silhouette — featuring squared lenses with softened corners, a wide keyhole bridge, and sculpted temples for everyday wear that holds its shape and presence.
Crafted from 100% bio acetate—a premium, plant-based material—our frames embody sustainable elegance. Rich in texture, biodegradable, and free from petroleum-based plastics, they unite timeless design with modern responsibility.
What You Feel, Your Brain Follows
Light is input. At night, harsh wavelengths keep your system wired when it should be winding down. Our evening lenses correct that misalignment—so your eyes relax, your mind settles, and sleep comes naturally.
FILTERS SLEEP-DISRUPTING LIGHT
Blocks stimulating blue-green wavelengths to support melatonin and wind-down.
TUNES YOUR BODY CLOCK
Aligns light signals with your circadian rhythm for deeper evening recovery.
BUILT FOR NIGHT CLARITY
Anti-glare, low-light lenses to reduce strain and sharpen focus after dark.
SCULPTED FOR COMFORT
Lightweight bio-acetate frames that stay put and disappear on the face.
THE PROBLEM
Modern light is misaligned with human biology. Blue wavelengths overstimulate the brain, disrupt melatonin, and strain the visual system—especially at night.
Hidden Strain
Your laptop’s brightness is calibrated for clarity—not circadian health. Evening use delays melatonin release and overstimulates the brain’s alertness pathways.
Small Screen, Big Signal
Phones compress high-intensity light into a short distance from your eyes. That overstimulation tells your brain it’s daytime—right when it should be shifting into rest mode.
Brightness Without Boundaries
Large-format screens flood your system with blue light—stimulating alertness at the exact moment your body needs to power down. RedSpec filters help recalibrate your internal clock.

Your System Wasn’t Built for Artificial Light
Our evening lens helps your brain recover from a world that stays lit too long, too bright, too blue.
RECOVERY BEGINS BEFORE SLEEP
Your system doesn’t shut off—it downshifts. Our evening lenses ease late-day stimulation so your body can move from alert to at ease.
CALM THROUGH COLOR
Color isn’t just aesthetic—it’s information. Our red tint signals your brain to slow down, soften tension, and prepare for rest.
DESIGNED FOR DOWNSHIFT
Slip them on. The world dims, and you do too. This is your cue to disconnect, drop in, and recover—without friction.
This Is What It Feels Like
Your eyes exhale. The glare softens. Noise recedes. A slow calm moves through your system as light dims to a warmer hue. Thought loops quiet. Muscles loosen. You’re no longer alert—you’re attuned. This is what winding down should feel like.
More Questions?
Clear answers for curious systems. Explore how our evening lens helps recalibrate your biology—one wavelength at a time.
Our night lens is engineered to block short-wavelength light—primarily in the blue and green spectrum—to reduce photic stress, protect circadian integrity, and help your nervous system wind down. It’s a physiological tool for sleep readiness and recovery.
By filtering out wavelengths under 500nm (especially the 460–480nm range), the lens helps preserve melatonin production and reduces overstimulation—two critical factors in falling asleep faster and sleeping deeper.
Our red lens filters approximately 78% of light under 500nm, including HEV blue and parts of green light. It offers a Tsb (blue light transmittance) of 22.19%, meaning over 77% of HEV light is blocked.
Short wavelengths (blue/green) are interpreted by your brain as daylight. They suppress melatonin and trigger alertness—keeping your nervous system wired when it should be resting.
Absolutely. They’re designed for screen-heavy evenings—filtering artificial light from phones, laptops, and TVs to help your brain disengage and your body prepare for rest.
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 low-light precision.
For best results, begin wearing them 1–3 hours before your intended bedtime. This aligns with your natural melatonin curve and cues your system to wind down biologically—not just mentally.
RedSpec Red lenses reduce late-day neural arousal by lowering photic input and have been linked to increased Late Positive Potential (LPP)—a brainwave associated with emotional regulation and nervous system calm.
We don’t just block light—we design optical tools for sensory alignment. RedSpec is built on circadian biology, neurological impact, and material integrity. It’s lab-grade function in wearable form, with aesthetics that match your system.
Engineered with CR-39 Lenses
CR-39 is a high-purity optical resin known for clarity, durability, and lightweight comfort. Originally developed for aerospace, it resists scratches, minimizes distortion, and preserves contrast—chosen for performance, not trend.
