Blue light exposure at night has been proven time and time again to be disastrous to your body’s internal clockwork. Your brain tracks the time of day with special receptors in the eye that sense lighting conditions. They are specially tuned to be sensitive to blue light. This is a problem because blue light exposure after dark sends daytime signals to your brain. This can scramble you natural circadian rhythm. Not Good… The Disruption Zone 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 and cyan wavelengths that clear and yellow tint lenses are helpless to block. Virtual Darkness 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! Make them a part of your evening routine Wear you new glasses 1 -2 hours before bedtime. For best results wear them even when not using electronic devices. Make them a regular part of your evening routine. The Secret “Sleep Hack” of High Performers It's amazing how many top level entrepreneurs and athletes use blue blocking glasses at night. Up until recently, it has been a closely guarded performance secret. There is more than one major league team using blue blocking glasses at night. It's not surprising really. Great sleep = great recovery! Allow fast sleep onset By preventing blue light from decimating your melatonin levels, you are giving yourself an opportunity for a great night of sleep. You need darkness at night! Treat yourself. Block the blue in the evening and allow your sleep onset to come naturally. Natural Rhythms of light and darkness 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. We all know how great a good night of sleep feels!

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 ### ⭐⭐⭐⭐⭐ Truly Effective for Nighttime Blue Light Blocking *by R***N on June 10, 2025* These glasses are exactly what I was looking for!

I bought them to block glaring headlights while i was trying to drive after dark . it had gotten to where I could not see to drive safely due to the LED and High Intensity headlights people are using now. I looked at the reviews on every pair of blue blockers on Amazon... i really did. this pair had an 80 and the closest was 76. Then i did some research outside of Amazon and found that the claims made by this mfg was inline with what other sources said about blue light and UV and green etc. So i took a chance. Last night I drove home from a wedding/reception 3 hours away from my home. I told my wife I'd drive until i experienced a problem. I pulled into my drive way and felt like I didn't have a problem the whole way. mountain roads, Highways, two lane roads i was in varied conditions including rain at night. I was able to see well enough to not have a problem. it literally makes the other headlights look yellowish to varied degrees. I'm not a scientist, I'm a 72 year old who doesn't want to have to depend on someone else driving to be safe at night. These have accomplished that and they fit well and are very comfortable. I feel like I have regained my independence/dignity back a little more and I don't have to ask my wife to drive like I was doing for about the last 6 months. Thank you for a GREAT product~ I highly reccomend this product ! ## Frequently Bought Together - Spectra479 - 99.9% Blue Light Blocking Amber Glasses for Sleep - Medium Adult Size Nighttime Eye Wear - Special Orange Tinted Glasses Help You Sleep & Relax Your Eyes - Epi-paleo Rx: The Prescription for Disease Reversal and Optimal Health - Honeywell Uvex Ademco Skyper Blue Light Blocking Computer Glasses with SCT-Orange Lens (S1933X) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.kw/products/730940623-spectra479-99-9-blue-light-blocking-amber-glasses-for-sleep](https://www.desertcart.com.kw/products/730940623-spectra479-99-9-blue-light-blocking-amber-glasses-for-sleep) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-15*
