Why It Works
Protects Melatonin
Blocks the blue and green light that tells your brain to stay awake, so melatonin rises on schedule.
Faster to Sleep
Wear them 1–2 hours before bed and your body starts winding down before you do.
Evening-Grade Filter
The deep red lens blocks far more of the sleep-disrupting spectrum than daytime orange.
Screens Without the Cost
Watch, scroll, or work at night without paying for it with worse sleep.
Block the light that keeps you wired, and melatonin rises on time — so sleep comes when you do.

Nasal Strips

Earplugs
Silences noise that breaks sleep cycles.
Blue-Light Glasses
Protects your rhythm before bed.

The Nox Sleep Protocol
A product blocks light. A system changes how you sleep. Every Nox order includes the Nox Sleep Protocol — a 12 page, science-backed guide to engineering your nights: light, temperature, breathing, timing, and the routine that ties them together.
It's the difference between owning a sleep mask and actually sleeping better.

Common questions
What's the difference between the red and orange glasses?
Different jobs, different times of day. Nox Wind Down (red) is for the evening — it blocks far more blue and green light to protect the melatonin that gets you to sleep. Nox Focus (orange) is for daytime screen work — cutting strain so you stay sharp. Red to wind down, orange to perform. Many people use both.
When should I put them on?
Ideally 1–2 hours before bed. That's the window when evening light does the most damage to your melatonin, so blocking it then has the biggest effect on how fast you fall asleep.
Won't the red lens make it hard to see?
You'll see a strong red shift — that's the point, and it's only for evening wind-down, not all-day wear. You can comfortably watch TV, scroll, or read on a screen. They're not made for tasks that need true color or for driving.
Do these actually help me fall asleep faster?
By blocking the light that suppresses melatonin, they let your body start its natural sleep process on time instead of being held in daytime mode by your screens. Paired with the mask and the Protocol's timing routine, it's a meaningful edge on how fast you drop off.
What's the Nox Sleep Protocol I keep seeing?
A 12-page, science-backed guide included with every order. It shows you how to engineer your nights — light, temperature, breathing, and timing — so the mask becomes part of a complete system, not just a product.
