The two hours
before bed
are everything.
Red-lens eyewear that blocks blue and green light — the two wavelengths that keep your brain in daytime. Put them on after dinner. Sleep like you remember.
It's not just blue light.
It's blue and green.
Melatonin, the hormone that unlocks sleep, is suppressed by two overlapping wavelength bands. Block only one, and you're doing half the job.
Phones, overhead LEDs and TVs all emit wavelengths in the 400–570nm band. Your pineal gland reads it as 'noon' and holds back melatonin.
Red-tinted polycarbonate filters the full melatonin-suppressing window. Your body reads 'night' while you keep living your evening.
Melatonin + sleep quality
Blue-light-blocking glasses worn 2hrs pre-bed produced significant melatonin increases and sleep improvements.
Shift-worker recovery
Amber-lens glasses during night shifts prevented melatonin suppression from artificial lighting.
Sleep-onset insomnia
Lenses blocking blue + green wavelengths for 3hrs pre-bed significantly reduced time-to-sleep.
A two-hour
wind-down.
No supplements. No apps. No batteries. Just the slow, steady rise of your own melatonin.
Put them on.
After dinner, at dusk, the moment you're home — doesn't matter. The sooner the better.
Live normally.
TV, reading, phone. The lens filters the wavelengths; you still see everything.

Your body begins its natural hormone cascade. Heavy eyelids arrive unprompted.

"I've tried melatonin gummies, magnesium, mouth tape. These just… work. I'm out within 15 minutes now."
"Shift-work brain, mid-forties, doom-scroll problem. My Oura ring is showing the best deep sleep numbers in two years."
"I'm a skeptic. But watching TV in these vs without — I actually get tired. Morning wake-ups are sharper."
