How they work:
Wearing Sundown Eyewear with PaleoTech Lite 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:
These circadian rhythms (daily hormone changes related to light) govern much of our most basic biology. Re-synchronizing this hormone system results in not just a better sleep, but better brain function, better athletic performance and better metabolic function.
When you circadian biology works better you get clearer thinking, better decision making, more energy, better focus, more motivation and improved body composition (weight loss).

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% 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.

These not designed to fit over prescription glasses.

Best results are realized if used 90 min prior to bed and after 7 to 10 nights of continuous use.

Screens can be difficult to view as a result of lens blocking blue and green light. We suggest using the 'greyscale' (black and white) screen setting for best function and better yet, avoid screens when possible.

The right arm of our kids eyewear has proven to be tighter than we would have ideally liked. They still function perfectly but it takes a slight bit more effort to open it all the way than it should. As a result we have included a bonus pair free of charge. Enjoy.
