Description

Blue light at nighttime has become a serious problem. Blue light suppresses your body's natural melatonin production which can cause problems getting to sleep. Wearing a pair of 99%+ blue blockers can help. By blocking 99.9+% of light in the Disruption Zone, we are creating a personal “virtual darkness” bubble. Safely use computers, tablets, and phones after dark Protect yourself from blue rich LED and florescent lights. Allow your body to shift effortlessly into nighttime physiology Enable rapid sleep onset and deep natural sleep cycles Virtual personal darkness can be taken with you anywhere you go! CAUTION: Not for use while driving Blocking all blue light means that blue police lights will look more like orange construction lights! Please drive safely. NOTE: Does not fit over other glasses Please search for Spectra479 Fit-Over glasses Blue light exposure at night has been proven time and time again to be disastrous to your body’s internal clockwork. Your body tracks the time of day with special receptors in the eye that sense light levels. They are extremely sensitive to blue light. This is a problem because any blue light exposure after dark creates conflicting signals. Your biorhythms can become fragmented and distorted. Not Good… While the body is sensitive to higher levels of all visible light, the range of 450 - 510nm is by FAR the most disruptive. This is longer blue wavelengths that clear and yellow tint lenses are helpless to block. The wraparound fit keeps out nasty blue light from creeping around the sides and top of the lenses. Because the frames are flexible they fit a wide range of head sizes and shapes. They are so comfortable that you might even forget that you have them on! It's amazing how many top level entrepreneurs and athletes use blue light blocking glasses at night. Up until recently, it has been a closely guarded performance secret. By preventing blue light from decimating your melatonin levels, you give yourself an opportunity for great sleep. Give your body the darkness it needs in the evening and allow your sleep onset to come naturally. We all know how great a good night of sleep feels. Stable patterns of light and darkness provide a solid foundation for health and wellness. This is a major component of a healthy lifestyle that is only recently becoming recognized.

My eyes feel less tired and my sleep seems better
Color: Nighttime
I’ve used these for two nights now and will update my review at a later time. I will say that I’ve noticed some improvements after 2 nights of use. I suffer from a lot of sleep issues due to bipolar disorder, adhd, medications, and family history. I have a sleep study scheduled in December and this year I’ve been willing to try just about anything. I’ve known about glasses like these for a long time but only took it seriously after another bout of restless sleep and sleep deprivation last week. To be fair, Amazon lost my B12 and D3 supplement which I was out of for several weeks. I started taking it two days ago so maybe that’s part of it. However I’ve also had sleep disturbances while on the supplement. I’ve tried Valerian root and ZMA. I’ve bought a special pillow. I use an eye mask and try to use white noise. I do live 75ft from the interstate barrier wall this last year which I suspect contributes to my poor sleep. However as I’ve said this started years ago. Anyway, these glasses are my latest trial and I’ve definitely noticed an improvement. Ive felt more refreshed while waking up and my smart watch that I purchased a couple weeks ago is showing that although my deep sleep is too low and rem and light sleep too high, both deep sleep and rem have happened earlier in the night and been less sporadic after falling asleep. I know I need to get outside more often because I WFH and have a tendency to stay inside. But my habits have been to stare at the computer for work all day, my phone during breaks, and then the TV after work. I would sit downstairs until 12-12:30am watching tv with my boyfriend. Just never felt like I’d get mentally tired but it’s also been a struggle taking Adderall. Last two nights I’ve noticed that around 10:15 - 10:30 I get this natural inclination to get up and start getting ready for bed. I’m slowly moving my bed time back and seem to fall asleep okay. I feel more refreshed waking in the mornings (as much as one can be with the winter sunrise being at 7:30). I especially like that these wrap around. They block out almost all light around my line of vision and when I take them off everything has almost a blue tint and makes me squint. I use LED lightbulbs and read that LED has blue light more than the old incandescent. I’m considering buying redder lightbulbs for the bedroom since I read those are better for your circadian rhythm than LED with the blue light. So far I definitely recommend these. I read a lot of reviews like I do with every project. The only thing I don’t like is that the stems are long but I have a smaller head and they don’t seem to push forward much at all even when resting my head back. The glasses do have a plastic cheaper feel to them which isn’t an issue for me. They aren’t fragile but I’d definitely recommend keeping them in a hard case when not in use. 10/10 would buy again if they broke. And this isn’t a company that sends shady review us for a gift cards with the order. I’m reviewing because the quality is superb imo. Oh and some reviews say these distort their vision. I had lasik in 2019 after wearing Prescription glasses for 11 years. These do not distort my vision to an extent I notice a detriment for reading or watching tv. I can tell vision is minimally changed but I think this is due to the curvature. It will make things sepia seeming but I’ve been using f.lux with the deep Orange night filter on my computer for years and prefer that anyway. ... show more

Better than expected!
Color: Nighttime
I began to suffer of eye strain, dryness, eye floaters, a bit of photophobia since 2010 and snow vision since 2013. I used to watch TV in dark rooms and be infront of the monitor for hours, back in the day, however I had no idea why those things suddenly appeared in my vision. So I got very worried. I started to make a thorough research in every source available about the matter. I also went to the oculist doctor and he said that eye floaters are a very common condition and around 85% people in the world actually have them, but they just don't about the thing, and the only risk about the condition is when the retina could detaches causing blindness. The snow vision problem, though it is very common as well, there is no confirmed evidence so far of what the real causes are. With all the information I had at hand years ago, I found out that the blue light spectrum that artificial devices emit, such as TV's, laptops, cellphones, tablets, etc, are really harmful for the eyes in the middle and long term. I have to be clear with this again: The natural blue light spectrum that comes from sun light is GOOD for your health and eyes, but the artficial blue light spectrum that comes from electronic gadgets and street lights is BAD for your health. First, I bought a pair of Eagle Eyes. They are great for wearing outdoors, but for indoors they are very obscure. Then I bought a Gunnars and though my eye fatigue, itchy eyes and redness decreased, my circadian rythm was still a mess, so I thought I needed something with more blocking capabilities. I bought then the Uvex Skyper by Honeywell and they do really block the dangerous blue spectrum in a way that everything that is blue at that specific risk level becomes green or black, eye strain was gone and my circadian rhythm improved considerably. Although they work very well, the only problem that I see with the Uvex is that they are very bulky, some people say they are ridiculous and cumbersome to wear and they aren't polarized. I finally bought the Spectra 479 (BioRhythm Safe) and I was impressed by the very first moment I wear them on. Natural light comes to the eyes like a waterfall of light without hurting the eyes at all. Everything looks clearer and brighter and at night or when infront of monitors or the TV, then the harmful blue light spectrum is also blocked at all. Eye fatigue, with wearing this pair, is also gone and dryness in my eyes is no more. They include a soft fabric to store and clean. No rigid case, but I think it is just than enough. The only bad point with the Spectra 479 glasses is that the frame seems to be a little bit fragile, so I would recommend to be careful when handling them. For some people, wearing this kind of blocker glasses may reduce the overall experience when watching a movie, working in the computer, especially for designers, or playing a video game, due to the fact that the colors of things are somewhat altered, but then one has to put aside sometimes joy and comfortness for the sake of health. If you want to make yourself a favor and give your eyes and body the rest they need, with the best of protection in order to avoid future eye damage, then buy a blue blocker glasses. And in my personal opinion I would buy the Spectra 479 as the first and best option available. ... show more

Good Quality, Comfortable, What's Not to Love?
Color: Nighttime
I love that these give full coverage. They're one of the few pairs that I have found that are this style. They're very comfortable. They don't squeeze too tight or too loose, they have a sort of flexibility to them, and they don't feel cheap at all. They will change the color you see. They're designed for nighttime use, but if I have a headache or my eyes are hurting, I throw these on during the day sometimes for a bit and I honestly think these make a HUGE difference. I have worn them outside before just as an experiment and it's actually kind of cool. I have another pair that's from a different company for daytime use, and I will switch off periodically between these and those. Usually I just use these for nighttime, but I used them for a while as my sole pair and my eyeballs didn't explode or pop out. I believe they don't recommend using them all day because your body actually needs some degree of blue light to maintain balance and hormone levels and stuff out of my pay grade (feel free to do some research). They will change some colors, but not all. You can still see most everything on the computer screen just fine. The only time I really had a problem was when I was sitting there staring at a graph that had a black background and multiple colored graphs (LTspice) and wondering why the graph didn't look like it was supposed to until I lifted up my glasses and realized there was a blue trace on there too 😂 Also once, my external hard drive has this annoyingly intense blue light that flashes when its on and I was wondering why it wasn't on one day, well... you get the picture. They definitely do the job and do them great. I am normally pretty sensitive to all the bright lights. I have things resting on top of various items around my room because of their annoying LEDs everywhere. It's crazy how many things are always shining! If you ever want to test these out, just put them on and look at your stove and microwave light (probably blue like mine). Love them! ... show more

4th time's the charm.
Color: Nighttime
These are the best blue blocking glasses out there. I bought 3 different pairs before these, the first ones had yellow lenses and only blocked a small amount of blue light (a total waste of time & money). The next pair were the UVEX safety glasses, which block almost all blue light so they're great for wearing at home, but since they look so stupid, you don't really want to wear them when you're out at night (like at the gym, for example). The UVEXs have served me well for almost a year now, but I wanted a pair that I could wear out of the house at night. So, I tried the Swanwicks. It seems to me that they don't block quite as much blue as the UVEXs do, and I really didn't like the style... they're completely flat with square lenses and they let light in the sides, which probably isn't a good idea when the whole purpose is to block as much blue light from getting into your eyes as possible. Seems to me you would need a wraparound style frame to serve this purpose. (Plus, the Swanwicks were crooked when I got them. To their credit, they gave me a full refund and didn't even ask me to ship back the glasses!) Now for the Spectra479s. Like I said, these are by far the best. They block as much or more blue light than the UVEXs, but they don't look stupid/silly... they actually look really good and I wouldn't be embarrassed to wear them out in public at night at all. They are very comfortable and light weight and they have that wraparound style frame to block your periphery. Do yourself a huge favor and buy a pair of these not only for yourself but for everyone on your Christmas list too. As far as I can tell, you can't beat the style, the performance, or the price, of these glasses! ... show more

Helps with sleep
Color: Nighttime
I've been wearing these glasses for approximately 3 weeks and have to say they have really improved my sleep. You have to get used to everything being orange and one of the reasons it works is because it's hard to be on your devices while wearing them. They really do reduce the blue light. Some letters and numbers are hard to see and reading can be a bit blurry. I put them on at 8pm around the time I watch tv. They also seem to destress my eyes when I put them on. I've ordered a pair of the clip ons for my glasses to see how they work. I can still use my devices when wearing them. Overall very pleased. ... show more

A miracle for my insomnia!
Color: Nighttime
MIRACLE for sleep! I have bought dozens of sleep supplements with either awful side effects or no help at all. For at least two years I have relied on antihistamines in desperation for 6 hours of broken sleep. Then…these glasses! I wear them for about 3 hours before bedtime. I take them off only to wash my face, and I keep my eyes closed. I wear them when watching tv, on phone etc., but also just in the lighting in the house. For the first time in years, I am sleeping 7-9 hours of sleep. I have a smart watch which tracks the lovely deep sleep and rem sleep I am getting. If you have trouble sleeping, try these glasses. If you aren’t committed to wearing them consistently, they will not work nearly as well. If you have been desperate for sleep, I highly recommend them. Ordering a second pair in case they are lost or broken. They are super comfortable and I adjusted quickly to softer colors on screens. highly recommend! ... show more

Effective, great fit for large head, and aesthetically pleasing design at an affordable price point
Color: Nighttime
I’ve tried several glasses of this type around this price point and I’m very impressed with the lens and frame quality and especially the fit of the frames on my large head. I was cursed with a very large head and the competitor glasses I’ve tried (while generally nice products in their own right) are engineered for much smaller headed beings. As a larger headed being, that has annoyed me. These glass address all my needs, including efficient blue light removal, comfortable fit on my large head, stylish look, and an affordable price point. Normally, I do not care about aesthetics, but my job requires me to be on camera with colleagues around the world much of every day, so I very much appreciate the chic look. I strongly recommend these glasses for anyone struggling with screen-related migraine headaches (as I do), and those who spend a lot of their work day in front of screens and on-camera. For the price, I don't think you will be disappointed. I’ve only had them for 2 days, so time will tell if they hold up. But, so far, I am very impressed. In fact, I am so impressed with fit, style, and light filtering efficacy I ordered a second pair so I can have a pair conveniently located/usable in both my home and work offices. I've received many compliments/questions about them from my colleagues around the world. ... show more

Good range covered and not dark, a yearly purchase.
Color: Nighttime
Been doing this for decades since when they were hard to find. Been through dozens of types. This review is at the life’s end of my second pair of spectra. These cover a fuller spectrum than most oranges in the price range without going into red territory. They fit my narrow face without much leakage, but many larger people seem to fit them too. This pair (spectra 479) has decent optical quality for the first 6 months to a year, but the coating eventually starts to bubble and peel from the inside of lens, then optical quality is shot. Hinges are still fine and have never been retightened. I take care of my glasses and they are kept in lens cloth bags, and if traveling also inside a case. they have held up without scratches for over a year. This includes occasional drops, which often puts specks or scratches in cheap lenses but these held up. Most likely it is not compatible with skin oils and they eventually take a toll on clarity. Apparently I am allergic to the frames and get a small rash near my eyebrows, but not bad enough to deter use. I get this from many glasses. I find most led light painful and alarmingly unnatural feeling, warm or cool white, cooler being worse. Been through enough glasses and spectrogram charts to guess they are around OD-3 or 4, perfect for most household indoor situations. Good glasses for people who have poor lowlight vision and complain when other glasses are dark, some brands can be like sunglasses. I myself am very sensitive to intensity, and when it comes to melatonin/ melanopsin, I have a very wide spectrum- so I have several kinds and use what suits the environment at the time and if I am near bedtime or not. Some led lights will itch my eyes in the daytime and I have lighter ones for that too. Some family members need an insane level to see and these are not the ones I wear at night if the family lights are triggering pain, shielding or flinch reactions. That means most people can comfortably read text or a screen with them. I am starting to lean more to glasses made by optical companies for the clarity/ distortion factors, but these are good for the price. The better blue blockers work, the less color rendering you have. No way around it and keep that in mind if you try to use them for “computer glasses” purposes rather than strictly evening melatonin purposes. Those are different purposes, ranges of spectrum blocked, level of blue blocked and often VLT. ... show more
