What is Junk Light

Junk light is the over-exposure to artificial light at the wrong time of day that can aggressively inhibit your melatonin levels and the physiology of your eyes. Artificial light sources, especially LEDs, compact fluorescent (CFLs), computer, smartphone, and eReader screens are nearly unavoidable. These light sources amplify the blue, green and purple parts of the light spectrum.  Your body’s sleep-wake cycle, also known at your circadian rhythm,  is incredibly sensitive to this spectrum of light. When exposed to it at the wrong time of day or night, you end up with junk light, which impacts your ability to get quality sleep. Thousands of studies show that poor sleep leads to a host of other physical and emotional issues.

How Does Junk Light Affect My Health?

Deep, restful sleep is essential for allowing your mind and body to heal, recuperate, and recover from the stress and exhaustion of the day. 

Junk light impacts photoreceptor cells in your eyes, and suppresses the natural production of of the sleep hormone, melatonin, which throws off our body’s internal clock, disrupting our ability to sleep deeply and restfully. Junk light also emits a unique glare that impacts your retina causing eye strain, headaches, and physical and mental fatigue.

Junk light may contribute to and, or be linked to many chronic health conditions, including but not limited to:

  • Eye strain
  • Headaches
  • Short-term memory loss
  • Problems sleeping, due to melatonin suppression
  • Stress and anxiety, due to cortisol suppression
  • Symptoms of Seasonal Affective Disorder or depression
  • Endocrine disruption and a poor immune system
  • Female hormonal/menstrual cycle disruption
  • Weight issues
  • Agoraphobia (anxiety disorder)
What is TrueDark® technology and how does it work?

Daywalker EliteTrueDark® is a health and wellness consumer brand created by Biohacked (and co-founded by Dave Asprey) that uses patented technology to help people protect their eyes and improve their quality of life. TrueDark® products essentially optimize your exposure to harmful light – day or night – restoring your circadian rhythm and bringing balance to your mind and body.  Think about TrueDark® technology solutions like noise-canceling headphones for your eyes. They protect your internal processes from the disruption, chaos and noise of the world. They help you feel, live and be better.

How do TrueDark® Daywalkers work?

TrueDark® Daywalkers are designed for daytime use and work to:

  • Filter out the harshest blue light wavelengths emitted by LEDs, electronics, phones, tablets and computers
  • reduce daytime eye strain
  • improve overall sleep
  • synchronize your circadian rhythm

While some blue light during the day is good for you, certain wavelengths disrupt your circadian rhythm. Whether you’re using a computer, watching TV or walking outside, junk light is impacting your performance both inside and outside. TrueDark® Daywalkers will help you find the right balance of blue light exposure from artificial light sources.

How are TrueDark® Daywalkers Different Than Traditional Blue Blockers?

It’s simple – inexpensive blue blockers do exactly what they say they do. They block all blue light from your vision.While it’s true that overexposure to blue light can have negative effects like trouble focusing, weight gain, eye strain and poor sleep,your body actually requires some blue light at certain times day, and from the right sources, for optimal performance!

TrueDark® Daywalkers are unique let in the precise amount of blue light that you need to signal to your body that it is daytime. This light tells your body that it should be active, focused, and energetic. TrueDark® Daywalkers’ scientifically designed, highly advanced lenses operate on a more advanced level than traditional blue blockers.

How Do TrueDark® Twilights Work?

Patented TrueDark® Twilight is the first and only solution designed to filter out ALL of the sleep-stealing and performance-robbing wavelengths in the evening before bedtime. With over 10 years of research and development behind them, patented TrueDark® Twilights have multiple optic filters which block out all wavelengths of the junk light which disrupt your sleep. This signals to your body that you are in complete darkness (even though you can still see!), tuning your circadian rhythms so that you have a deep, restful, restorative night of sleep.

TrueDark® Twilights prevent your melanopsin cells from detecting the wrong wavelengths of light at the wrong time of day. In other words, it protects your melanopsin from the entire light spectrum that negatively impacts your biological clock — including blue, green and purple light. Wear TrueDark® Twilight for 30+ minutes before going to bed to help your mind and body reach an alpha state and fall asleep with ease.

Note that when you don’t get the proper amount of sleep at night, you become susceptible to health issues, including but not limit to: macular degeneration and other vision problems, cancer, aging, diabetes, stroke, obesity, neurodegenerative diseases, autoimmunity and gastric conditions. #StopJunkLight with TrueDark ® Twilight technology and free your hormones and neurotransmitters to::

  • Improve sleep quality – maximize control of your circadian rhythm. Your body doesn’t signal melatonin if your melanopsin-infused sensors are seeing daytime colors. Note that common blue blockers don’t cover the wavelengths that impact melanopsin.
  • Reduce brain inflammation – increased melatonin release = lower brain inflammation.
  • Support weight loss – Leptin is a light sensitive hormone that peaks at night and signals to our brains how much fat storage we have. Red light and darkness move leptin levels into patterns associated with less hunger.
  • Increase energy and focus – Better sleep and less eye strain result in more energy.
Why use TrueDark® Daywalker and Twilight glasses together?

TrueDark® Daywalker glasses can help you manage the calibration of your circadian rhythm during the day, freeing your hormones and neurotransmitters to do their best work and  resulting in:

  • Improved sleep quality
  • Feeling sharper and more focused
  • Increased energy
  • Reduced brain inflammation
  • Improved mood

TrueDark® Twilight glasses can be used at night as part of your sleep and environmental junk light strategy to address:

  • Stress and anxiety
  • Seasonal affective disorder
  • Endocrine disruption
  • Poorly functioning immune system
  • Weight issues
  • Insomnia

Further, studies have shown that junk light may contribute to macular degeneration, cancer, aging, diabetes, stroke, obesity, neurodegenerative diseases, and gastric conditions. TrueDark® glasses are proven to filter or block this very same junk light. When used in combination, TrueDark® Daywalkers and Twilights restore your circadian rhythms to their natural state, improving your performance and give you more energy, focus, and clarity on a daily basis.

What wavelengths are blocked by Twilight eyewear?

TrueDark® Twilight glasses block 590Nm and below - basically all blue, green and violet. We block the broadest spectrum on the market! Melanopsin is very sensitive to green and violet, as well as blue.

What wavelengths are blocked by Daywalker eyewear?

Our Daywalker glasses filter approximately 50% of wavelengths between 370nm and 500nm. Full 100% blocking during the day is not ideal because your eyes do need SOME blue light to function properly.

Why are the Twilight Elites/Fitovers lenses slightly lighter in color than the Twilight Classics?
As we are always working to improve our technology and designs, the Twilight Fitovers are the result of extensive testing and customer feedback. The feedback on the Twilight original glasses was that they were "too dark." Because of, this, we did additional research and testing that allowed us to find a balance that lets in more orange, red and infrared - which provides more light - while still blocking the worst wavelengths of junk light. Our research shows that the very slight increase in green and cyan does not significantly reduce their potency, so it simply makes it a little easier to see and not trip over things on the floor (like your kids' toys, the dog, etc.) They are just as effective as the original ... just with improved visibility!
