THE SCIENCE

Backed by the research — engineered beyond it.

Eight independent university studies have shown that filtering blue and blue-green light before bed supports earlier melatonin release, faster sleep, and deeper rest. The lenses tested in those trials blocked 40–80% of that light.

SleepSpec blocks a lab-verified 98%.

SleepSpec wasn't tested in these trials — it was engineered from them. Every lens specification shown to work is built into our product, then taken further.

Screens Are Stealing Your Sleep

  • The Problem

    Your evening screens emit the wavelengths your brain reads as daylight — delaying the melatonin that puts you to sleep.

  • The Science

    That signal lives between 400 and 520 nanometres. Filter those wavelengths before bed and the wake-up cue quiets.

  • The Solution

    SleepSpec lenses block 98% of light across that range. Wear them an hour before bed: your screen stays bright, your brain stays dark.

How to Wear SleepSpec

  • 1. Put them on

    1–2 hours before bed. The earlier in your wind-down, the cleaner the signal to your brain.

  • 2. Use your screens

    Watch TV, scroll, work, read. The lenses do the filtering while you do what you'd do anyway.

  • 3. Take them off

    Drop them in the case on your bedside table. Lights off, no wake-up signal, ready for sleep.

Frequently Asked Questions

How long before bed should I wear them?


Wear SleepSpec glasses for 1-2 hours before your intended bedtime while using any digital devices or under artificial lighting. This timing allows your body's natural melatonin production to begin unhindered.

What makes SleepSpec different from regular computer glasses


SleepSpec glasses are specifically engineered for evening use, blocking 98%+ of sleep-disrupting blue light. Computer glasses only reduce daytime eye strain and typically block just 20-45% of blue light - insufficient for sleep protection.

Can I wear them over prescription glasses?


Our current model is designed as standalone glasses. For prescription wearers, please contact customer service to discuss options.

Do they work for all screen types?


Yes! SleepSpec glasses protect against blue light from all digital devices - phones, tablets, computers, TVs - as well as LED and fluorescent lighting.
