Why you need blue filter glasses ... Blue light affects your performance. It regulates the sleep / wake cycle. However, in today's world, we are exposed to an excess of blue or artificial light. This applies to hours spent in front of televisions, telephones and computers, too. And that includes the time we spend with artificial light through LEDs and fluorescent lamps. Even if we only read a book, we do so with artificial light that emits much more blue light than the sun. This excessive exposure to junk light during the day has a dramatic impact on our neurotransmitters and hormones responsible for a good night's sleep. TrueDark® Daywalker glasses filter out the excess of junk light from artificial light sources when you're indoors, working on a computer, watching TV, or wherever junk light is affecting your performance. Some blue light during the day is good for you, and TrueDark® Daywalker help you find the right balance between blue light and artificial light sources.   Why TrueDark? TrueDark is the brand of Dave Asprey. He is co-founder of TrueDark and Bulletproof. Although more and more blue-light glasses are available, they are of widely varying quality and effectiveness. TrueDark is currently one of the best brands on the market.   Scratch-resistant glasses The Daywalker ELITE glasses block 75% of the blue light. During the day we need only little blue light to set the inner clock. What we get from computer work and artificial light is too much. The Elite glasses help you block out superfluous blue light. The lenses are made of scratch-resistant polycarbonate, colored throughout and also protect against UV light. Scratch resistance is an important quality feature, as low quality glasses that scratch will no longer function properly.   Cool design The frame is made of high quality lightweight aluminum. Thanks to the suspension in the hinges, the glasses fit the head perfectly. They look cool and modern and cover the eyes largely.   All advantages of these glasses at a glance Scratch-resistant polycarbonate lenses Blocks 75% of the blue light Lightweight and optimized fit Hardshell case Micro fiber cleaning cloth Recommended by Dave Asprey Practical during the day, when you have to spend a lot of time in closed rooms or work a lot on the computer Carry the elite during the day in places with strong artificial lighting or when working on the computer. So you can avoid the fatigue of your eyes. In the evenings, the Elite supports melatonin production and help you unwind.  

Truedark®-Brillen mit klarer Linse sind ideal für Menschen, die in Umgebungen arbeiten / leben / spielen, die mit künstlichen blauen Licht aussendenden Leuchten beleuchtet werden und lange Zeit blaues Licht aussendenden Geräten (Fernsehgeräten, Computern, Tablets, Handys usw.) ausgesetzt sind. Klare Brillengläser sind ideal für Menschen, die unter Schlafstörungen oder zirkadianen Rhythmen leiden. Die Brillengläser mit klarer Linse sind auch ideal für Schichtarbeiter, da sie in den dunklen Stunden, in denen sie wach sind, empfindlicher auf künstliche Beleuchtung reagieren können, was ihren natürlichen Schlaf-Wach-Zyklus / Tagesrhythmus stört. 40% des blauen Lichts wird durch die klaren Linsen blockiert. Unsere Clear Lens-Modelle sind eine großartige Lösung, wenn du in einem Beruf arbeitest, in dem farbige Gläser nicht das richtige sind, zu viel Aufmerksamkeit auf sich ziehen oder deine Arbeit behindern.

In der heutigen Welt sind wir jedoch einem Übermaß an blauem oder künstlichem Licht ausgesetzt. Dies gilt auch für Stunden, die vor Fernsehgeräten, Telefonen und Computern verbracht werden. Und dazu gehört auch die Zeit, die wir mit künstlichem Licht durch LEDs und Leuchtstofflampen verbringen. Selbst wenn wir nur ein Buch lesen, tun wir dies mit künstlichem Licht, das deutlich mehr blaues Licht als die Sonne aussendet. Diese übermäßige Exposition gegenüber Junk-Light während des Tages hat einen dramatischen Einfluss auf unsere Neurotransmitter und Hormone, die für einen guten Schlaf verantwortlich sind. TrueDark® Daywalker-Brillen filtern den Überschuss an Junk-Light aus künstlichen Lichtquellen, wenn du dich in Innenräumen aufhälst, am Computer arbeitest, fernsiehst oder wo immer sonst Junk-Light deine Leistung beeinträchtigt. Etwas blaues Licht während des Tages ist gut für dich, und TrueDark® Daywalker hilft dir, das richtige Gleichgewicht zwischen blauem Licht und künstlichen Lichtquellen zu finden. TrueDark® Daywalker reduziert die Anzahl der blauen Wellenlängen, die sich negativ auf deine Biologie auswirken, und hilft: blaue Wellenlängen, die von LEDs, Elektronik, Telefonen, Tablets und Computern emittiert werden, zu reduzieren die Augenbelastung während des Tages zu reduzieren den allgemeinen Schlaf zu verbessern deinen circadianen Rhythmus zu synchronisieren Eigenschaften: Leicht dünne Ränder Federscharniere für eine individuelle Passform klare Gläser Blaues Licht blockierend Kratzfeste, entspiegelte Gläser aus Polycarbonat Mikrofaser-Reinigungstuch Blockiert ungefähr 40% des blauen Lichts

  Why use blue light filter glasses? Blue light affects your performance. Your body uses light of different colours to set your biological clock properly. Blue light for daytime and red light for the evening. Artificial light and screens emit a lot of blue light. Being exposed to it all day can disrupt your day-night cycle. Excessive blue light also puts extra strain on your eyes, which can become an issue when you use your computer for a long time. So consider using eye strain glasses if you spend a lot of time inside or working with your computer. These glasses can also help when you work shifts and are extra sensitive to bright light during the day. Why choose Daywalker Fitovers?

  Why you need blue filter glasses ... Blue light affects your performance and regulates your sleep / wake cycle. It ensures that the melatonin (the "sleep hormone") production is reduced or suppressed. The less melatonin, the harder it is to fall asleep. In the evening you should avoid blue light as much as possible. Artificial lighting and screens (whether television or PC monitor and LED lighting) are therefore often the reason for bad sleep quality or problems to fall asleep.When blue light is inevitable in the evening, blue-filter glasses block the harmful light and melatonin can be produced.
