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. Our glasses are worn as PRE-SLEEP glasses and are not for use while sleeping
