Review on 👓 Uvex Skyper Blue Light Blocking Computer Glasses with SCT-Orange Lens (S1933X) - 3 Pack by Jason Fanney

As an amateur astronomer I have done a lot of research on light pollution. This prompted me to explore how light affects sleep. Here's a summarized version so you don't have to read all the scientific papers I have: Blue light is great for staying awake, so wake up with blue skies (read wikipedia on melanopsin and melatonin) Blue light isn't good for sleep; in the 470 nanometer range, which suppresses melatonin (a key hormone for good sleep). Wavelengths of light have been the only source of light at night (fire/candles) for most of human history. Tablets/phones/screens/LEDs and many CFLs have strong blue wavelengths that disrupt our circadian rhythm and suppress melatonin production because they have wavelengths shorter than 530nm - 540nm. So what to do in our modern world? Wear these glasses before bed. The natural production of melatonin in our ancestors must have occurred at sunset. The wavelengths of the setting sun's light were meant to turn red, and fire or candles were usually the only form of light available. They are both relatively faint and have longer wavelengths. There is a lot of blue light in our networked world today. This disrupts our sleep patterns as our bodies have evolved to see only red/orange/yellow light at night and NO blue light/short wavelengths. THESE GLASSES BLOCK THE MELATONIN SUPPRESSION WAVES. Put them on a few hours before bed. As for me, I feel sleepy about 90 minutes after wearing it. The trick is to NOT take them off without your eyes closed and in a dark room (ONLY a room with dim red light will do as your melanopsin will not cause melatonin suppression with the red light). Therefore, after going to bed, close your eyes, take off your shirt if you need to pull it over your head, or put on night clothes. Then leave them until you turn off the sleep light. And be sure to sleep in the dark or wear a sleep mask. A small amount of light can still affect your melatonin (well, anything brighter than a full moon—yes, even the blue LED on your computer). You can watch TV with them, check your phone, read on your tablet, work on your laptop - just be aware the colors will look odd. Blue looks black. Yellow looks white. The green looks weird. And the glasses aren't exactly stylish. But when you sleep better, who cares? They work. And while you're at it, make sure the lights in your home (and your business, if you have one) aren't shining on other people's homes. Too much light at night makes these things necessary. At night we don't need all the light; these glasses are just a band-aid to help; What we really need is smarter outdoor lighting—grounded, in the right color(s), so we don't suppress others' melatonin. According to a Harvard study, the US loses $63 BILLION annually due to American insomnia. Artificial light at night disrupting people's sleep is no doubt part of it - let's fix that so those glasses aren't so necessary. Oh, did these glasses suit me? A resounding YES, they have. Slept great 5 nights (so far) and a rested morning. And I'm NOT a lark! They work - just use them properly and make sure you're not doing other things that can interfere with your sleep (too much caffeine, too little or too much exercise before bed, sleep apnea, etc.). State of health, do the right thing, wear that and sleep better.
