Sleep (protection from melatonin suppression)
Stress reduction for the eye (protection of sensitive photoreceptors)
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
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.
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.
Fall asleep faster, sleep better through the night
After ordering the glasses, they arrived at my home just 2 days later.
Wear them every evening for 2 hours before going to bed and feel DEEPLY that my body comes to rest, my eyes turn off and I become more tired.
The first evening was of course a bit unusual, due to the fact that everything is perceived more orange. From the 2nd evening, however, this was no longer a problem. Even when watching movies, I do not feel any impairment by the colored lens, only light blue colors are perceived slightly differently.
Fall asleep much faster and better through the glasses

Super glasses!
I the glasses came very quickly after ordering and are qualitatively very well processed. The effect after a few days is also exactly as already described by others here. I am satisfied all around!

Very great glasses
I previously had glasses from a cheap supplier. When I decided to order one from Lichtblock and tested it, I was really overwhelmed. I have a lot of LED lights at work and used the glasses a lot. It's actually amazing, but the blue light is filtered out very well. Blue LEDs or even an ambulance with blue lights, all of this seems like it's swallowed up with the glasses. Really cool I must say.

I wear the glasses for almost a month in the evening and find that I fall asleep much better and also through. I am very satisfied, although a wider range of shapes would be nicer.
Beautiful glasses that I no longer want to miss in the evening. My friend watches TV more often in the evening and I read, the light often bothered me. With the glasses everything is much more pleasant.
Ordered. Paid. Delivered very quickly. About the product: My 3-year suffering (dry eyes by day and by night, sleep disorders) is just coming to an end. The irritation of my eyes due to screen work etc. has noticeably and immediately subsided. Clip-on is a perfect complement. I am happy and very satisfied. Thank you very much
I can only agree with the many positive reviews: Very good material, wonderful wearing properties. Price phenomenal! Everything fits! In addition, I would like to emphasize the very good and particularly friendly interaction with the customer!.You do not often find that nowadays. Thank you very much!
Love wearing the glasses, you can tell a stark difference.
My friend also wears his every night while streaming on Twitch. At first he was not so enthusiastic but now he also says he can sleep much better afterwards. Again, an absolute recommendation, we love
The Oro is a bit more expensive, but you get a high quality frame that is absolutely robust and can be super adjusted to the head. I already had glasses in light orange and have now bought the Oro in dark orange, because I wanted to improve my sleep even more. I put the glasses on and get tired within 10 minutes. Love them. 👌
The glasses are really great. I wear them in the evening and am actually tired much faster. The yellow light is very pleasant for the eyes and the mood. Also, the service is excellent. I had to exchange something. That went very promptly and very courteously over the stage. And also in an incredibly friendly tone. Very high praise and an unconditional recommendation - both with regard to the products and the company!
I bought the clip-ons in the bundle and use both since I have them (as far as it is socially acceptable) every evening after dusk has set in.
At first I was skeptical - but my sleep and especially the "fatigue" in the evening has become noticeably better.^^
Simply absolutely recommendable. :)
Thank you for your work.
Super, pleasant glasses. Totally relaxes the eyes. Sleep is much better. Watching TV is great with the glasses, does not distort the image, you have to get used to the fact that the colors appear warmer (more yellow), but after a short time you get used to it and it is just pleasant. I am now finally no longer pushed up by the television and I go to bed relaxed. Really only to recommend. Such a simple and inexpensive way to improve his quality of life. TOP!!!
Mega excited about the glasses, the eyes are super relaxed and it's just fun to wear the glasses. Also, proximity to all colors more intense. Without glasses everything seems gray.xD
I have the feeling that my sleep quality has improved somewhat and fall asleep I now "do" within minutes.
Thought I have also my 16 year old son now to order one! ;)
