Lichtblock® Martello Sleep Blueblocker glasses

For restful sleep: the Lichtblock® Sleep series

The Sleep series was specially developed for the hours after sunset. It effectively filters out 100% of the blue light that prevents your body from switching to night-time sleep mode.

Advantages of the Sleep series

  • Improves your sleep quality: By blocking disturbing blue light, the Sleep series promotes a natural sleep cycle and helps you to fall asleep faster and sleep more deeply.
  • Relax your eyes: Long periods of screen time strain our eyes. The Sleep range reduces this strain and prevents eye strain and dryness.
  • Effective and with no extra effort: simply put it on and enjoy the immediate effect. No need to change your habits in the evening or do without technical devices.

The problem: blue light in the evening

  • Do you spend a lot of time in bright surroundings in the evening?
  • Are you often busy with screen work?
  • Do you like to watch a film or a series in the evening?
  • Do you have problems falling asleep or staying asleep?

Then the use of blueblockers may make sense for you.

The crucial and biggest problem with blue light after sunset is the effect it has on our nervous system. After dark, the light tricks your brain into thinking it's the wrong time of day. This interrupts your sleep cycle and can have a negative effect on your health, especially over a longer period of time. Blueblockers can help you to protect your sleep cycle and improve your sleep quality.

Difference between LEDs and fire

Lichtblock Blueblocker Graphic LED Spectrum Bluepeak

LED spectrum

We speak of blue light at a wavelength of approx. 380 to 495 nanometers (nm). This is short-wave and very high-energy light. Modern displays, LEDs and energy-saving lamps have a disproportionately high proportion of blue light. This stimulates certain photoreceptor cells and can lead to a dysregulation of your sleep-wake rhythm. This can have a negative effect on your hormones and metabolism.


Fire (candlelight)

Before we were able to turn night into day through the invention of electricity, there were only natural sources of light in the form of fire. The big and decisive difference to today's light sources is the distribution of the light spectrum. Blue and green are hardly present in candlelight, as can be seen in the graph. Furthermore, fire has no flicker effect, which can stress your nervous system. Therefore, fire usually has a calming effect.

Good thing

When I put the glasses on for the first time and looked out (during the day, mind you), I was amazed! I had never experienced anything like it before. The glasses really reliably filter out most of the blue. Blue towels appear gray, with strong blue LEDs you can still see some blue. The effect has convinced me. At first I even started yawning after wearing them for a short time. My quality of sleep has improved since then and the normal quality of light seems very cool without the glasses.
The eyes also don't feel so strained if you look at a screen for a long time.
I would buy these glasses again.

great glasses and super friendly and fast customer service!

The glasses are great and when there was a small delivery problem (DHL had not informed us about the storage in the post office), I immediately received a friendly reply from customer service and the glasses were sent back to us in no time at all. Great, thank you very much!

Much better sleep!

Thanks to the Lichblock glasses, I get tired 1 - 2 hours earlier in the evening than usual and sleep much better overall! I wake up earlier on my own. The glasses allow me to be at the computer in the evening and still fall asleep well. A clear recommendation - a real game changer!

Grandiose!

I love the glasses from Lichtblock. I've already given them as gifts. If you value your health and your sleep, you definitely need Blue Light Blocker. An absolute recommendation!
