“Blue light in the evening is one of the most underestimated sleep disruptors. Red lenses block the spectrum that suppresses melatonin - the simplest circadian fix most people are not making.”
Dr Tom GurneyChief Science Officer
  • 1x Ultra Blue Blocking Glasses
  • Red lenses - blocks 99%+ of blue and green light (400-550nm)
  • Protective carry case
  • Microfibre cleaning cloth

Put them on 60-90 minutes before your target bedtime. Wear them for anything involving screens or artificial light - phone, laptop, TV, overhead lighting.

Consistency matters more than duration. Wearing them every night for 2 weeks recalibrates your melatonin timing more than occasional use for longer.

Blue and green light in the 400-550nm range is detected by intrinsically photosensitive retinal ganglion cells (ipRGCs), which signal directly to the suprachiasmatic nucleus - your brain's master clock.

This signal suppresses melatonin production and delays circadian phase. Red lenses cut this signal at the source. The result is melatonin rising on its natural schedule, not 60-90 minutes late.

What they do

Four things you'll notice.

Sharper thinking.

Every REM cycle your brain clears cognitive fog and resets focus. Red lenses protect the melatonin timing that keeps those cycles running - so you wake up sharper.

Better emotional balance.

REM sleep regulates how your brain processes stress and emotion. More of it means smaller reactions to setbacks, better decisions, and a mood that doesn't crater by midday.

Stronger memory.

What you learn today gets consolidated during REM. Blocking blue light protects the melatonin signal - and the sleep cycles that turn short-term experience into long-term memory.

More complete sleep.

Most people lose REM without knowing it - pushed later by blue light, then cut off by the alarm. Red lenses shift your sleep earlier so your cycles have room to finish.

Sharpen your mind with Red Lenses

Sharpen your mind with Red Lenses

REM sleep is critical for brain performance - blue light kills this. Red lenses block 99% of blue light, protecting your REM and sharpening your mind.

Our brains were not designed for blue light

Our brains were not designed for blue light

For hundreds of thousands of years, our species's sleep schedule was governed by sunrise & sunset. 140 years ago, this all changed with the invention of the light bulb. Fast forward a century and a bit, we have florescent blue light emitting devices in our pockets. Our brain still thinks this is sunlight and therefore it cannot be night time - so your brain doesn't release melatonin - this is the sleep hormone that kickstarts the magic.

FAQ

You have questions. We have answers.

When should I wear them?

60-90 minutes before bed is the target window. This is when melatonin should begin rising - and blue light exposure during this period delays that process most significantly.

Put them on when you sit down to wind down. That means screens, lighting, everything.

Do they actually block blue light?

Yes - the red lenses filter 99%+ of blue and green light (400-550nm). This is the full wavelength range that suppresses melatonin production and signals alertness to the brain.

Standard yellow-tinted "blue light glasses" typically block 10-30% of blue light and do nothing meaningful for sleep. These are not those.

Can I use them with screens?

That's the point. They're designed specifically for screen use in the evening. Phones, laptops, TVs - the red lens colour distorts colour slightly but vision is otherwise normal.

Do they replace good sleep habits?

No tool replaces consistent sleep timing, a cool room, and limiting stimulants in the evening. The glasses remove one specific and significant barrier - light-driven melatonin suppression - that most people are hitting every night without realising it.

Use them alongside 8HOURS SLEEP for the full circadian support stack.

Are they prescription compatible?

These are non-prescription lenses only. If you wear prescription glasses, they can be worn over most frames or used during the parts of the evening you don't need precise vision.

Our promise

Buy them. Use them every night for 30 days.

If you don't notice a difference in how quickly you fall asleep, return them for a full refund. No questions.
