Honeywell Uvex Ademco Skyper Blue Light Blocking Computer Glasses with SCT-Orange Lens (S1933X)

As an amateur astronomer, I've done a lot of research about light pollution. That led me to research about how light affects sleep. Here's the summed-up version so you don't need to read all those scientific papers I have:- Blue light is great for being awake - that's why you wake up with a blue sky (read about melanopsin and melatonin on Wikipedia)- Blue light is not good for sleep; in the 470 nanometers range, that suppresses melatonin (a key hormone for sleeping well)- Humans (and other animals) evolved to sleep in the dark - or, at the darkest, full Moonlight (just 0.1-0.3 lux of light)- Longer wavelengths of light were the only source of light at night for most of human history (fire / candles)- Tablets / phones / screens / LED's and many CFL bulbs have strong blue wavelengths that are messing with our circadian rhythms and suppressing melatonin, because they have wavelengths shorter than 530nm - 540nmSo what to do in our modern world? Wear these glasses before bed. Natural melatonin production would have occurred with our ancestors starting with the onset of sunset. Wavelengths of light from the setting sun would have shifted to red, and fire or candles were usually the only form of light available. Those are both relatively dim, and in longer wavelengths.Today, our "connected" world has a LOT of blue light. It's messing with our sleep patterns, because our bodies evolved to only see red/orange/yellow light at night, NOT blue light/shorter wavelenghts.THESE GLASSES BLOCK THOSE MELATONIN SUPPRESSING WAVELENGTHS.Put them on a couple hours before bed. For me, I start getting drowsy about 90 minutes after wearing them. The trick is DO NOT take them off without closing your eyes or being in a dark room (a room with ONLY a dim red light would work too, as your melanopsin won't trigger melatonin suppression with red light). So when changing for bed, close your eyes when removing your shirt if you have to pull it off over your head or put your night time clothing on.Then leave these on until you turn out the light for sleep. And be sure to sleep in the dark too, or wear a sleep mask. Small amounts of light can still affect your melatonin (well, anything brighter then full Moonlight - yes, even a blue LED on your computer). You can watch TV with these on, check your phone, read your tablet, work on your laptop - just note that colors will look weird. Blue looks black. Yellow looks white. Greens look weird. And the glasses aren't exactly stylish.But if you sleep better, who cares? They work.And while you're at it, make sure your home's lights (and business if you own one) aren't shining into other people's homes or apartments. Too much light at night is what makes these things necessary in the first place. We don't need all this light at night; these glasses are just a band aid to help; what we really need is smarter outdoor lighting - aimed down, at the ground, at the proper color(s) so we aren't suppressing others melatonin. According to a Harvard study, the U.S. loses $63 BILLION dollars per year due to American's insomnia. Artificial light at night messing up people's sleep is undoubtedly part of that - let's fix that so these glasses aren't as necessary.Oh, and did these glasses work for me? An emphatic YES, they did. 5 nights (so far) of excellent sleep and well-rested mornings. And I am NOT a morning person! They work - just use them the right way, and be sure you're not doing other things that might hurt sleep (too much caffeine, lack of / too much exercise right before bed, sleep apnea, etc.) So if it's not a medical condition, do the right things, wear these, and get better sleep.

I've suffered from chronic sleep problems my entire life, and recently discovered I have DSPD (Delayed Sleep Phase Disorder), so I have made several changes to attempt to improve my sleep pattern. First I bought a Light Therapy light (which I'll review separately after a little more use), and then I downloaded software that reduces the blue light glow from my computer's monitor. I also stopped sitting under a bright lamp every evening and now have a dim mini-lamp/nightlight that I turn on in the evening instead. And finally I bought these orange blue-blocking glasses. So now every morning I use the Therapy Light, and every evening I put on the glasses, and dim the both the room light and the PC monitor. I've only been doing this new routine for a few days so it's too early to speak for sure of results, although I can already report that I've fallen asleep and woken up almost exactly one hour earlier each day since I started all the above things, which in and of itself is a bit of a miracle for me. I'm still about 6 hours off a "normal" sleep schedule, but it's a great start.The glasses themselves are better than I expected in both quality and usability. They are true safety glasses, Z87 rated with polycarbonate lenses, although that doesn't matter much for my use. I was testing out a yellow-lensed pair of shooting goggles that I happened to already have when I first learned about this sleep/blue-light thing, but I read that orange was really ideal for blocking blue light so I ordered these. I was expecting the orange to be much darker than the yellow, but it's actually not bad at all. I find that it enhances the colors and tones of most things and I've actually come to really like how things on the screen look through them. Screen images with a lot of bright blue colors are now a rich, deep green and things look generally warmer and richer. They definitely block blue light too, my proof was that my blue modem light completely disappears when I look at it with these on, which is kind of strange but impressive. The modem light was altered but still visible through the yellow lenses, so orange is clearly better for this usage.The temple length (arms) is adjustable as well as the tilt. For example when I first put them on the bottom of the lenses were pushing into my cheeks but I realized I could adjust the angle outward a little and now they're perfect, so that's a handy feature. There is a full wrap to these, so I'm not getting any peripheral light coming in. I put these on at night mainly for my computer use but I'm quickly developing the habit of wearing them all around the house in the evenings right up until bedtime to avoid exposure to any bright lighting before bed, kitchen and bathroom lights for example. It was a little awkward at first but they've become quite agreeable and I feel good knowing I'm taking these steps toward a better night's sleep. I feel much more relaxed at night now too, wearing these combined with dimmer room lighting; it really helps me get into "winding down mode". I bought two pairs, one for my computer room and another for my nightstand for when I use my Kindle in bed (which I now try to avoid). Very glad I learned about these. I do wish they came with a little draw-string case however, but for the price I can't complain.
