How they work:
Wearing Sundown Eyewear with PaleoTech red lenses in the evening reduces the negative effects of artificial light exposure. It does this by mimicking natural light exposure that, as the evening darkens, signals our brain to prepare for rest.
Why they work:
Circadian rhythms (daily hormone changes related to light) govern much of our most basic biology. Re-synchronizing our hormone system results in not just a better sleep, but better brain function, better athletic performance and better metabolic function.
The second way these eyewear function is by significantly reducing the light received by your eyes prior to bed. Our lenses block 92% of all the incoming light to function as 'Dark Therapy' eyewear that enhances melatonin response and sleep.
Avoiding screens and artificial lights is the best practice but if artificial lights and screens are unavoidable, these eyewear are the next best thing.
Sundown Eyewear block 99.8% of blue and green light under 580nm. That's all the wavelengths of brain exciting, sleep disturbing light. Blue, green and bright light suppress the onset of the sleep hormone melatonin resulting in difficulty falling and staying asleep.
Screens can be difficult to read as a result of blocking blue and green light. Use 'greyscale' (black and white) screen setting for best function but avoid screens when possible since they're not conducive to sleep.
You may see some faint purple or violet, this is normal. Refer to our transmission values (<435 or >750nm)
Our eyewear is designed to fit large faces with the foam removed (5' wide at temple) and small faces with the foam attached (4.5" wide at temple). These are not designed to fit over glasses.
Best results are realized when used at least 30 min (or more) prior to bed and after 7 to 10 nights of continuous use and in conjunction with a comprehensive sleep strategy that aims to strengthen circadian rhythm.
- Block 99.9% of the full spectrum of blue and green light (400nm to 580nm) for better sleep. WHY RED? Studies show that green light disrupts sleep just like blue light and our PaleoTech red lens blocks both. Orange lenses don’t block green light.
- DARK THERAPY: Is the process of greatly reducing exposure to any light during the hours before sleep. This is done to prevent the breakdown of melatonin by blue (and green) light, which is an important hormone involved in regulating the bodily circadian rhythm. Our eyewear offers a novel approach to dark therapy for sleep because they are designed to block 92% of total light as well as 99.9% blue and green light. Darkness improves sleep.
- IMPROVED CIRCADIAN RHYTHM: This is the goal. It has been shown to benefit nearly all aspects of health and recovery. Better sleep is just one important result of improved circadian rhythm. The darkness created by our eyewear is an important component to strengthen this rhythm but it must be accompanied with increased daytime light exposure (bare eyes)to be most effective. For best results a comprehensive strategy should be implemented (refer to diagram).
- FEEL BETTER NATURALLY - Conditions that show improvement from circadian rhythm regulation include: Sleep Disorders, Weight Management, Sports Performance and Muscular Recovery, Lyme Disease, Infertility, Jet Lag, Anxiety, Diabetes, Postpartum Depression, Seasonal Affective Disorder, Bipolar Disorder, ADHD, Neurodegenerative Disease, Heart Disease, Cancer and other Metabolic Related Diseases and Conditions.
- Notes: 1. This model is not designed to fit over glasses. 2. These dark lenses are designed to mimic darkness - it’s one of the reasons they are so effective. Therefore, they are quite dark and are best used while relaxing before bed while doing pre-sleep activities like reading. 3. The red colour of the lens may take 10 minutes or more to get used to. 4. Effects are best realized after 7 or more nights of continuous use. 5. 1 or 2 nights is an insufficient test of the products effectiveness.
