How the Everyday 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.

The master switch

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.

What Everyday filters

The light reaching your eyes. And what we take out.

Every color is a wavelength of light. Flip the toggle to watch Everyday lift the blue spike out of the spectrum.

100% of blue light reaches your eyes

Without lenses, the full blue-heavy spectrum reaches your eyes.

The lens

It's in the lens.
Not on it.

The Everyday 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 95% of the stimulating blue light in the 400–465nm band — the exact range screens spike hardest — and lets the warm, useful light pass through. Your screen colors stay readable. Nothing goes dark.

What the lens does

Filter the harsh light. Keep everything else.

Focus that holds past 3pm.

Everyday steadies the screen light that swings your dopamine — so your drive doesn't spike and crash by mid-afternoon.

It filters the high-energy 455nm spike that wears your eyes down and leaves them dry and aching by the end of the day.

The correction

Your world, still yours.

Only the harsh blue comes out. Warm light passes straight through, so colors stay true and nothing goes dark.

Everyday is half the day.
Dusk takes the night.

Wear Everyday from the first screen to sundown. When the light goes warm, switch to Dusk and let your body find the night again.

Questions

The honest answers.

No. The amber is pigment embedded in the lens and tuned to filter 95% of the stimulating blue light between 400 and 465nm — verified by a third-party lab. Cheap blue-light glasses use a thin surface coating that filters only 5–20% and wears off.

Everyday's tint is a light amber. It lifts out the harsh blue spike but lets the warm, useful light through, so your screen colors stay readable. Nothing goes dark.

Yes — that's exactly what Everyday is built for. It's designed to reduce the screen-light overload that leaves your eyes tired and your focus fried by mid-afternoon, so you can wear it from your first screen to sundown.

Screen software only dims one screen. Everyday filters the light reaching your eyes from every screen and every bulb in the room — and it can't be forgotten or toggled off. It's a physical filter, not a setting.

The filtration is third-party lab measured: 95% of the stimulating blue band at 400–465nm. We publish the exact figure and never round it up to 100% — a real filter blocks a real, measurable amount, not “all of it.”

Everyday (lighter amber) is for daytime screens — focus and eye strain. Dusk (deeper amber) is for the hours before bed — it filters blue and green light to help your body wind down. Most people wear Everyday by day and switch to Dusk after sunset.
