How the Dusk lens actually works.
No hype — just the light it filters, the spec behind it, and the biology it protects. Every number on this page is third-party lab measured.
You don’t just see light. Your body runs on it.
Deep in your eye are cells that have nothing to do with vision — their only job is telling your brain what time it is. That one signal sets the systems below.
The light reaching your eyes. And what we take out.
Every color is a wavelength of light. Flip the toggle to watch Dusk lift the blue and green out of the spectrum.
Without lenses, the full blue-heavy spectrum reaches your eyes.
It's in the lens.
Not on it.
The Dusk tint isn't a coating sprayed on top that scratches off over time. The color is pigment set into the lens itself, so the filter never wears away. It absorbs ~99% of the blue and green light from 400 to 570nm — the light that keeps your brain in daytime — and lets only the warm end through. Your room reads as darkness to your body. You can still see everything in it.
Filter the daytime light. Give the night back.
"Tired but wired," gone.
Bright screens and lamps keep your stress signal switched on after dark. Dusk filters that light so cortisol can fall and your body stands down.
Fall asleep faster.
Evening screens hold melatonin back — by up to 90 minutes. Dusk blocks the blue and green light doing it, so the sleep signal arrives on time.
Mornings that start clear.
Protected melatonin lets your body drop into the deep, restorative stages of sleep — the difference between waking foggy and waking sharp.
Dusk owns the night.
Everyday owns the day.
Wear Dusk from sunset to lights-out. When the sun comes back, switch to Everyday and let it carry your screens through the day.
The honest answers.
No. The deep amber is pigment embedded in the lens and tuned to filter ~99% of the blue and green light between 400 and 570nm — verified by a third-party lab. Sunglasses just darken everything evenly; Dusk removes the specific wavelengths that keep your brain in daytime.
Yes. Dusk creates “virtual darkness” for your brain, not your eyes — it filters the light that fakes daytime, but you can still read, watch TV, cook, and move around your home normally.
After sunset, or roughly two hours before bed. The earlier you put them on in the evening, the more you protect your wind-down — but even 30–60 minutes before sleep helps.
A melatonin pill adds a hormone from the outside. Dusk works the other way — it removes the light that's blocking your own melatonin, so your body can release it on its natural schedule. No supplement, nothing added to your system.
Night mode dims one screen and mostly shifts blue. Dusk filters blue and green from every screen and every bulb in the room — and green light, which night mode leaves alone, is a big part of what holds melatonin back.
Dusk (deeper amber, ~99% of blue + green) is for evenings and sleep. Everyday (lighter amber, 95% of blue) is for daytime screens — focus and eye strain. Most people wear Everyday by day and switch to Dusk after sunset.
