Why HEVO?
How Your Body Clock Actually Works
Your brain and body has a built-in clock – blue light screens destroy it every evening.
Morning: Light says “wake up” → your body stops producing melatonin
Evening: Darkness says “time to relax” → melatonin starts flowing
Night: Deep sleep with maximum melatonin production
But here’s what actually happens:
Instagram → your brain thinks it’s daytime
Netflix → melatonin is completely blocked
Scrolling → your body stays in “day mode”
“Why can’t I fall asleep?!”
“Why do I feel like I got hit by a truck?!”
It’s not all light – only certain wavelengths between 380–550 nanometers. This is the exact blue/green light that tricks your brain into thinking it’s midday.
Your brain gets confused:
Every time you see these wavelengths after sunset, your brain thinks:
"Wait, the sun’s still up! Stop producing melatonin!”
Step 1: Block the confusion
How HEVO Fixes It
HEVO Sleep Lens blocks 99% of the wavelengths that confuse your brain. Suddenly, your environment looks like natural sunset light.
Step 2: Restore natural melatonin production
How HEVO Fixes It
Within 20 minutes, your body starts producing melatonin again – just like it’s supposed to after sunset.
Step 3: Reset your body clock
How HEVO Fixes It
You start feeling sleepy at the right time (around 9:30–10:30 PM) instead of being wired past midnight.
Why Most Blue Light Glasses Don’t Work
They block the wrong thing:
Regular “blue light glasses” only block 20–30% of the problem wavelengths.
HEVO goes all-in:
We block 99% of the exact wavelengths Harvard scientists identified as most harmful to melatonin. That’s why you feel the difference instantly.
