Advantages of the Dark series

  • Maximum light reduction: Blocks 100% of blue light and 70% of the green light spectrum up to 550 nm to protect your sleep cycle and improve your sleep quality
  • Ideal for extreme lighting conditions: Especially recommended if you are in environments where bright light is prevalent and you have little control over the lighting.
  • Promotes sleep quality: Supports the natural production of melatonin by minimizing exposure to light-induced melatonin suppression.

The problem: blue light in the evening

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.

Simply great!

I can highly recommend the glasses for watching TV and the glasses clip for my reading glasses. They are both part of my evening routine. I feel calmer in the evening and can fall asleep better.
The overall quality of the glasses is very high and so are the cases that come with them.
I had a few questions before buying which were answered very quickly and professionally. Thank you very much!

My 2nd pair of glasses

Having already had good experiences with the glasses clip for my television
TV glasses, I ordered another pair of glasses.
I need these for reading in the evening. I am very satisfied
with the products and have been able to fall asleep better since then.

Estoy encantada con las gafas. Mi hija utiliza las amarillas para estudiar con su portátil y yo utilizo las rojas en cuanto se va el sol, Estoy contenta, en cuanto me sea posible compraré el aro de luz. Gracias
