Legal Disclaimer CAUTION: not for use while driving Review: Excellent, and unlike any others. I'm delighted. - In summary: putting these on a couple of hours before bed time makes a huge benefit to my quality of sleep. If I combine this darkening the room somewhat an hour before bed and having a cup of camomile tea, then I sleep perfectly. In detail: I have done a lot of research on this, and most of the so called blue light filter glasses let large ranges of wavelengths through that are associated with circadian waking. This however, is the only pair I found the truly filter out ALL of the blue hues. This is easy to tell, as light and mid and light blues appear completely green or grey though these, and dark blues appear completely black. Soon after I put them on at 9pm every evening, I can feel the appropriate circadian relaxation that comes with the rising melatonin (caused by the absence of the melatonin-suppressing blue light) I can then continue to work at my pc/laptop or phone for a couple of hours without disturbing this natural biochemical trend towards sleepiness. As the intensity of light is also a factor in circadian rhythm (in addition to blue light proportion) I turn the light out in my study and turn the brightness and contrast down on my pc. These glasses mean that even if I go out to of the darkened study to the kitchen for example, the increasing relaxation towards sleep will not be broken (it only takes a few seconds of blue light, to reverse the effect, but these glasses prevent that.) Add a cup of camomile tea 45 minutes before bed, and if you get the same experience as me, you'll be sleeping better now than you have done for years. These glasses were hard to discover in today's online market-place that's full of so much rubbish. I'm so glad I found them, and as you can no doubt tell - I'm delighted ! Review: Great Mid-Price Product! - I am delighted with these glasses. I have been learning about the health benefits of blocking out blue light. I have been taking this a lot more seriously recently so was in the market for some good glasses. There are cheaper ones. There are more expensive ones. But these stood out as the best when looking into quality versus price. They are sturdy. They block blue brilliantly. They are slightly wraparound so they fit snug against the face. I am very pleased with the service as well. ## Features - FITS MEDIUM ADULT HEADS - For a larger size, search for our original style frames - BRIGHT LENSES - These are designed to pass as much non-blue light through as possible. There is no dark tint and they are not polarized. You can still make eye contact with loved ones and even forget you are wearing them. - FASHIONABLE FRAMES - Stylish and fashionable blue blocking glasses. - TECHNICAL SPECS - Tested to block 100% of light from 280 - 490nm (this includes UV). Blocks 99.9+% of light in the critical 450 - 510nm range. This is the most disruptive wavelength of light at night. It is also the same frequency of light that is blasted directly into your eyeballs from electronic devices! Always wear protection! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B076YQP6SB | | Best Sellers Rank | 123,991 in Health & Personal Care ( See Top 100 in Health & Personal Care ) 1,934 in Reading Glasses | | Customer reviews | 4.7 4.7 out of 5 stars (560) | | Date First Available | 30 May 2016 | | Department | Unisex | | Item model number | FBB1-RG-19-03 | | Manufacturer | Zendustries, Inc. | | Product Dimensions | 17.78 x 13.97 x 4.32 cm; 28.35 g | ## Images ![Spectra479 - 99.9% Blue Blocking Amber Glasses for Sleep - Medium Adult Size Nighttime Eye Wear - Special Orange Tinted Glasses Help You Sleep & Relax Your Eyes (Amber) - Image 1](https://m.media-amazon.com/images/I/617rNnO7GNS.jpg) ## Questions & Answers **Q: Can you provide documentation to back up that these are fda approved? you provide this claim in your technical specs.** A: Hello, Yes of course. In fact all sunglasses imported into the USA are FDA Class 1 Medical Devices and have spectral transmittance documentation on file. This is because of UV protection: Lens should have a UVB (280 to 315 nm) transmittance of no more than one per cent and a UVA (315 to 380 nm) transmittance of no more than 0.3 times the visual light transmittance. Also there is a lens shatter test (ball drop test) that is performed on a certain percentage of every shipment that enters the USA. Every pair of legally imported sunglasses in the USA conforms to these standards. We had to mention the FDA thing on the product listing because so many people were asking about it for some reason. By the way, the FDA has no definition or guidelines for blue blocking glasses. For people looking for specific spectral transmittance properties (like anyone looking for sleep glasses), it's buyer beware! Please ask sellers to provide spectral transmittance test reports for the glasses that they sell. https://en.wikipedia.org/wiki/Sunglasses#United_States Please contact us directly for more information. We also have a recent 3rd party spectral transmittance test report from Colts Laboratories in Florida that we can send you. **Q: Are the earpieces soft? They look uncomfortable to sleep in.** A: They're not soft at all but not uncomfortable. Like sunglass frames they're hard plastic. I don't suggest sleeping in them. Why not wear a sleep eye mask? **Q: Are these glasses recommended for use as sunglasses. if not, why not? i understand that they block uv just like good sunglasses.** A: No **Q: Why isn't this made goggle style to block out the light from above and on the sides? or do they make it?** A: Hello, no we do not make goggles. Depending on the shape of the face, these do a great job of keeping light out from above. They do sit fairly close to the face. Direct light and peripheral light from above is the most problematic. We recommend goggle style with foam inserts and red lenses to people that work night shift and wear blue blockers in the daytime. Because sunlight is WAY more intense than screens and LED lighting, we recommend blocking all peripheral light. We recommend SafetyBlue's Sleep Savior goggles (no affiliation to us) for that purpose.https://smile.amazon.com/gp/product/B07CZ499J5/ For those of us just using them 1 - 2 hours before bed at nighttime, these work very well. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent, and unlike any others.
