Clip-on Blue Blocking Amber Lenses for Sleep - BioRhythm Safe(TM) - Ni

May not work for lenses around 1/4 inch thick at the edgeI got these to put over my glasses to relieve eye strain due to computer use. They seem like they should work, but the edges of my lenses where the clip goes, are so thick that the clip just barely fit. The clip-ons tended to slide around and eventually pop off, because feet didn't have a good grip. I think they would work on lenses that are significantly thinner than 1/4 inch at the upper edge. Other reviewers have commented that the bridge of the clips are barely wide enough for the feet to touch both lenses. However, I'm not sure I'd want the bridge any wider so that the feet are in my field of view. So, I'm giving a 2 because they sort of worked for the short period of time they stayed on my glasses. Sadly, I'm returning them.2Works incredibly wellI've used a variety of glasses and lenses designed to block blue light over the past several years. These lenses work incredibly well. They are fairly dark, but you still have good optics to see through them. I find that I can work on my computer, watch TV, and read on a light-emitting device with them, and they'll allow me to be productive while still getting tired normally as if I didn't have blue light blasting my eyes. They also are constructed sturdily. My only disappointment is that they seem to scratch relatively easily, more than I would have thought. I bought them six months ago and they already have some scratches, whereas none of the other glasses/lenses that I've used do. I've told everyone I know, online, and offline, how great these are, but it will be tough to have to replace them often due to scratches.5Comfortable, works with my readers, think it helpsI already own a pair of Uvex Skyper Blue Light Blocking glasses, and they're good for when I watch TV or such, but they were not comfortable at all when I needed to wear reading glasses underneath. These clip ons by Spectra479 work great with my readers, and the clip is very easy to use. They are larger than my readers which I appreciate, since it helps to block light from the sides, top, and bottom (my Uvex glasses have side panels that help do that).I have "fitover" sunglasses, and considered those for using over my readers, but I am SO GLAD I chose the Spectra479 clip-ons instead. I am very sensitive to weight on my nose--my regular glasses before cataract surgery were frameless silhouettes--and these are comfortable for a good long while whenI'm working on my computer in the evening or reading a book. Every morning I remove them from my readers and store them in the plastic case that came with them. The very few times I've cleaned them I've used a microfiber cleaning cloth I've had no issues with scratches at all.I have also installed f.lux on my computer, and between these glasses, the f.lux app, and not watching intense TV a couple hours before bed, my sleep has improved a lot.I also appreciate the emails from the company checking to see if I have any questions and including a Quick Start Guide. These clip on blue blockers are a terrific investment in my quest for easier sleep!5The real dealThis is my second pair of blue blocking glasses I've purchased, the first pair slipped over your existing glasses and were very uncomfortable, pinching the sides of the head and causing headaches- they also didn't block very much blue light. I returned them and decided to try these. They are immensely more comfortable, as no part of the glasses touches your face, they clip over your existing glasses. They also feel like they are a lot higher quality than the ones I had before.Using an aquarium light that only emits blue light, I did a before-and-after with these glasses on. The effect is even more pronounced in person, the light almost completely disappears so it is clearly doing its job and rejecting blue light away from your eyes. I'm impressed and excited to see how they work in reducing eye strain and (hopefully) helps me fall asleep faster.5The lenses themselves are fantastic, fit over my prescription glassesI was skeptical when I bought these lenses as to how well they would work with my prescription glasses. My wife and I watch TV before going to sleep at night and wanted to try blocking out the blue light to see what affect it would have. The lenses themselves are fantastic, fit over my prescription glasses, and are extremely easy to put on and off. I just purchased another pair for my wife. Regarding blue light in general, I have tried these lenses 3 nights in a row and do notice a difference when going to bed and being a little less stimulated. Also, watching at night with these lenses on will definitely cut down on the overall eye strain. Not specific to these lenses but to all blue blocking lenses, your TV picture will not be as colorful. So, watching TV at night on my 4k HDR Samsung with any blue blocking lenses on takes some getting used to, but in my opinion the decreased eye strain and overall stimulation before going to bed is worth it!5You'll be pleasedI will say up front that I rarely write reviews, and that my motivation is solely to encourage the many, many people who spend hours in front of the computer for a living to give consideration to this product and, second, to support a vendor who did a top notch job.The short of it: I've had these but a week, but I am feeling the benefits in terms of eye strain and, I believe, insomnia (I have another medical condition that overlaps with the latter, as it were, but the eyestrain has greatly abated even in the past few days. These are sturdy, sturdier than a similar pair I lived by for some time, then broke. Being on a tight budget, I bought after a few months an over-the-glasses of a type I vaguely remember grampy having back in the day. I'm not a proud man, yo, but ... 'nuff said.In any event, these are sturdy and effective, and handy enough, clipping easily onto my glasses. On mine, they fit perfectly. The other point of most interest is whether they work. As noted, I am noticing far less eye fatigue, and given the breadth of information on the page, and that can be ascertained from googling the information provided, I expect I'll be reaping that benefit when I'm finally on the mend otherwise.Kudos to the vendor for perfect shipping, both in terms of time (I have Prime, and this is the first time in ages I've actually received something in two days), and more importantly, in packaging it to ensure it wouldn't be damaged.I would definitely return to this vendor (pardon, word seems impersonal), without hesitation. To anyone perusing the other options out there, this is what you want. I checked out a large number of options, and this is the best value.5Don't stay onAlthough these lenses appear to be well-made and were the perfect shape for my husband's glasses, they were nearly impossible to get on straight, and once we did manage to get them on, they almost immediately slipped off to the side. After many attempts to get them to work, we had to give up and return them. His glasses aren't too thick, and they are a very common metal-frame style; the amber lenses did fit, the clip is just poorly-designed so they can't possibly stay on some glasses.1THE blue light blocking solution if you wear glasses!I've been using uvex glasses for several years and they work well except that I do need to use readers now I can fit the readers over the uvex glasses but it's not a perfect solution. These Spectra479 blue blockers are a perfect solution if you need to wear glasses while reading (for example). Other things that I really like about them: 1) the case provided is perfect for keeping the glasses unscratched and for traveling. It's a nice slim case ideal for packing. 2) the test image that they send is great. These glasses do block the blue light that causes the circadian disruption. The image also allowed me to check a couple of other pairs of glasses - the uvex check out fine, another pair not so good. Also bring up the image with and without f.lux and with and without the ios "blue blocker" to get an idea of how well these blue light solutions work. and 3) most important, they not only block blue light but the let a lot of other wavelengths through so things aren't too dark. Great lenses.5Good Blue-BlockersThese are very, very high quality clip-ons. They are very orange and should do a good job of block the blue light from the LEDs that light my desk and my bedside lamp. The only thing I don't like is they are not flip-up, as I'm constantly up and down from my desk, and in the winter when it's dark here in the Pacific Northwest daytime, I have to constantly remove them. Luckily, the attachment mechanism is spring-loaded, so I can move the clips away from the glasses lense so that when they are removed and re-installed, they don't scratch my glasses.4These almost literally saved my life.I've been suffering from extremely sensitive to bluelight eyes for several years. I'm the type with F.lux on at 1200K all the time, if I dare to watch a movie at a theater I'll get such a crippling migraine I have to lie down, I can't remember the last time I'd gone more than 3 days without at least a 5 out of 10 scale headache.After I bought these I immediately noticed their effectiveness on a 3 day weekend I spent at a friend's apartment, spending basically every waking hour staring at an unprotected TV with these on, and I didn't get a headache once. At first I only wore them when I was looking at an unprotected screen, then I started wearing them first thing in the morning to counter morning headaches. For the past week I've been wearing them all the time I've had my glasses on, which is every moment I'm awake and not showering. I honestly can't remember the last time I went a full week without a headache, but these made it possible.The longer I go without a headache the more I can feel the enthusiasm I felt I lost in life coming back. It's a wonderful feeling to focus on learning new things and enjoying working on a difficult problem without the constant, never ending throbs of pain in my cranium. I'd been meaning to leave a good review, and the past week of blissful painlessness finally got me off my butt and writing it out.As much as this is a review for potential customers, I also want to thank Spectra479 for making these glasses that literally changed my life. I honestly want a pair of your frames in my prescription and officially kiss the color blue goodbye!5
