  • 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 its effect on our nervous system. After dark, the light fools 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 long period of time. Yellow or orange lenses that block 100% blue light can help you 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 nanometres (nm). It is short-wave and very energy-rich light. Modern displays, LEDs and energy-saving lamps have a disproportionately high share 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. (1)


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.


Lichtblock Blueblocker Graphic Spectrum Fire Candlelight
Tip - Reduce the light intensity in your surroundings in the evening and create a relaxed atmosphere with alternative light sources such as our Lichtblock® Uno and candlelight.

A systematic review by Hester et al. (2) comes to the following conclusion:

Out of the 24 publications focusing on sleep, there was substantial evidence for blue-blocking glasses being a successful intervention for reducing sleep onset latency in patients with sleep disorders, jet lag, or variable shift work schedules. Given the well-established biological mechanism and clinical research showing that blue-blocking glasses are effective for inducing sleep, they are a viable intervention to recommend to patients with insomnia or a delayed sleep phase.
  • Our 500 models protect your eyes 100% from blue light and are very comfortable to wear, especially if you still want to see "colours" in the evening.
  • Our 550 models protect your eyes 100% from blue light and they still reach into the green spectrum. This can help to accelerate the formation of melatonin.

Game changer

It would be better if the glasses closed better on the sides. Thus, light effects penetrate laterally and reflections occur.

Contact by mail with the seller was fast and uncomplicated, I was well advised and received a good product. The glasses were slightly bent at first, but was quickly replaced with a replacement product.
I wear the glasses in the evening as soon as it gets dark and I am exposed to artificial light, get tired about 1 hour earlier than usual in the evening and sleep much better, wake up in the morning with energy, which I have not done for years.
Highly recommended.
