  • Fall Asleep Faster
  • Deeper, Sounder Sleep
  • 98% Blue-Light Blocked
  • 23g Ultra-Light Comfort

Keep the screens. Lose the sleepless nights.
Slip on SleepSpec 1–2 hours before bed. The deep amber lenses block 98% of the blue-green light (400–520nm) that suppresses melatonin — so you fall asleep faster, sleep more soundly, and wake up actually refreshed.
How SleepSpec Works

Evening blue light keeps your brain in “day mode” and suppresses melatonin. SleepSpec’s deep amber lenses block 98% of the disruptive 400–520 nm wavelengths, letting your natural sleep hormones rise so you wind down on time.

Key Advantages

  • 98% Blue- & Green-Light Blocking — spectrometer-verified deep amber optics create a gentle “digital sunset.”
  • Feather-Lite TR90 Frames — just 23g, 40% lighter than acetate, flex without snapping, and stay comfortable through movie-length sessions.
  • Built on What Research Shows — in randomised trials, blocking disruptive evening wavelengths before bed was linked with earlier melatonin, faster sleep onset, and better next-day focus. SleepSpec is engineered to exceed the filtration levels used in those studies.

Built for Trust

  • Every production batch is lab-tested for 98%+ filtration.
  • Covered by a 1-year warranty against manufacturing defects.
  • Trusted by hundreds of sleepers and designed for nightly wind-down routines.
The Research That Backs Us — and Why We Go Further

How SleepSpec Raises the Bar

Trials above used lenses blocking 40–80% of blue light. SleepSpec blocks a lab-verified 98% of the same 400–520 nm range, delivering a strong nocturnal darkness signal — without the heavy colour distortion of 100% blocking.

SleepSpec was not part of the trials listed. The studies show the demonstrated effect of reducing disruptive evening light; SleepSpec is engineered to exceed the filtration levels used in those studies.

SleepSpec — Fast FAQs
When should I put them on?
Put SleepSpec on 1–2 hours before bed whenever you’re under LEDs, TV glow, or phone light. That window gives your own melatonin time to rise naturally as your evening light exposure drops.
What makes them different from “computer glasses”?
Computer lenses are built for daytime eye strain and typically block only 10–45% of blue light. SleepSpec blocks a lab-verified 98% of the disruptive 400–520 nm wavelengths that keep your body in “day mode” — built specifically for night-time wind-down.
Can I still scroll, stream, or read?
Yes. The deep amber tint keeps colours usable for Netflix, e-books, reading, and gaming while giving your body a stronger “night-time” signal.
Will they fit over my prescription specs?
Our current model is a lightweight standalone frame. If you need a prescription version, drop our team a quick message — we’ll talk options or schedule you for the upcoming clip-on release.
Does side-light leaking in around the edges ruin the effect?
Not in normal use. The wide-coverage lens blocks the intense, direct 400–520 nm light that activates circadian sensors; any stray ambient glow is far below that threshold. Ultra-sensitive sleepers can pair SleepSpec with dim room lighting or a soft eye mask.
Why stop at 98% blocking instead of 100%?
Because 98% is the practical sweet spot: strong filtration across the disruptive 400–520 nm range without turning your entire world orange-black. Going beyond that usually adds heavy colour distortion, while SleepSpec keeps your evening routine usable.

Why SleepSpec Works

The circadian science behind the amber lens — in three short steps.

Macro eye in darkness with the iris subtly reading as a body-clock dial

Beyond vision, your eyes carry light-sensing cells that report straight to your body clock. Bright, cool-toned light reads as daytime; dim, warm light reads as evening. Everything you look at after dark is a time signal — whether you mean it to be or not.

Atmospheric blue-green spectrum band with a 400 to 520 nanometre label

Those clock cells are most sensitive to blue-green wavelengths — roughly 400–520nm — exactly what screens and LED lighting emit most. After dark, this light can suppress melatonin, the hormone that starts sleep, and keep your brain running on daytime settings.

SleepSpec amber lens turning cool phone glare into warmer evening light

SleepSpec’s deep amber lenses filter 98% of light across that full range, then ease off through warmer wavelengths so colours stay natural. Your brain gets a nighttime signal — while you keep watching, reading, or scrolling. Wear them for the last 1–2 hours before bed: the same cutoff window used in the research.

Protect Your Sleep

What better sleep feels like

The payoff of deeper rest shows up the next day. That’s why the hour before bed matters.

  • Sharper at work

Built for sleep. Not just screens.

Many blue-light glasses are designed for daytime. SleepSpec is engineered for the hours before bed.

Informed by published research. Researchers at the University of Houston found that evening amber-lens use raised night-time melatonin by ~58% and increased sleep duration by ~24 minutes (Ostrin et al., 2017).
