WHY
BLOCK.

The science is simple. Most people just haven't heard it yet. Here's what blue light does to your body — and why blocking it after dark changes everything.

01

Your brain can't tell the difference.

Blue light exists in sunlight and in every screen you own. After dark, your brain receives the same signal it would at noon — and responds by keeping you alert, elevating cortisol, and suppressing the hormones you need to sleep. It doesn't know it's 11pm. It just reacts.

02

Melatonin needs a signal to start.

Your body produces melatonin in response to darkness — specifically, the absence of blue light wavelengths. When screens are present, that signal never comes. Block those wavelengths after sunset, and your body gets the cue it needs. Melatonin rises. Sleep follows.

03

Cortisol is supposed to drop at night.

In a natural cycle, cortisol peaks in the morning and falls through the day. Evening screen use disrupts this — keeping cortisol elevated when it should be declining. The result: a wired, restless feeling even when you're tired. Blocking blue light accelerates the drop.

04

Deep sleep is where everything happens.

Muscle repair. Fat metabolism. Memory consolidation. Immune function. Emotional regulation. All of it happens in deep sleep — the stage that requires proper melatonin and low cortisol to reach. Better input, better output. Every night.

05

Why amber — not clear.

Most blue light glasses on the market use clear or lightly tinted lenses. They look normal. They're easy to wear. And they block very little — typically under 20% of blue light. The amber tint in BLOCKERS ONE exists for a reason: it targets the exact 380–500nm wavelength range responsible for melatonin suppression. You can't do that with a clear lens. The tint is the filter. That's not a design choice — it's physics.
