The Lens That
Helps You Sleep Better
Discover the Science
The science behind the tint
Light is not neutral.
It carries time.
Short wavelength light — the 400–520nm range — is the body's
primary signal for wakefulness. When artificial sources emit it after dark,
they tell your brain it is still midday. The result:
cortisol stays elevated, melatonin is suppressed, and sleep
erodes before you've even closed your eyes.
Our Red Lenses filter 100% of visible blue light and most green
light in the 400–520nm band. Our Amber Lens block
70–100% of high-energy blue light (400–440nm) — cutting
cumulative eye strain without disrupting your evening spectrum.
