Featuring bright, clear amber lenses with no dark tint, these lightweight TR90 frames provide superior nighttime protection to maintain natural sleep cycles while allowing natural eye contact. Ideal for professionals seeking to reduce digital eye strain and improve sleep quality without sacrificing style. ## Description 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… 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. ## Features - FIT OVER DESIGN: These glasses fit over top of prescription and reading glasses, allowing you to convert your existing eyewear into blue light blocking glasses. They can also be worn on their own - SUPERIOR BLUE LIGHT BLOCKING: The best selling Spectra479 amber lenses can now turn your prescription and reading glasses into anti blue light glasses for computer and nighttime tv use - BRIGHT & CLEAR 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 - TECHNICAL SPECS: Tested to block 99.9+% of light from 280 - 510nm (this includes UV). The wavelengths between 450 - 510nm are 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 - NIGHTTIME PROTECTION: Designed specifically for nighttime use to help maintain natural sleep cycles by blocking disruptive blue light from LED lights, fluorescent bulbs, computers, tablets, and phones after dark ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B08176FSKZ | | Date First Available | November 10, 2019 | | Department | unisex-adult | | Item Model Number | FO1-19-01 | | Package Dimensions | 6.42 x 2.48 x 0.67 inches; 1.1 ounces | ## Images ![Fit-Over Amber Blue Light Blocking Sleep Glasses For Prescription Glasses - Image 1](https://m.media-amazon.com/images/I/61sfou+o0xS.jpg) ![Fit-Over Amber Blue Light Blocking Sleep Glasses For Prescription Glasses - Image 2](https://m.media-amazon.com/images/I/61xKYp4HsNL.jpg) ![Fit-Over Amber Blue Light Blocking Sleep Glasses For Prescription Glasses - Image 3](https://m.media-amazon.com/images/I/912nKgsQyGL.jpg) ![Fit-Over Amber Blue Light Blocking Sleep Glasses For Prescription Glasses - Image 4](https://m.media-amazon.com/images/I/81zE9KQ4tCS.jpg) ![Fit-Over Amber Blue Light Blocking Sleep Glasses For Prescription Glasses - Image 5](https://m.media-amazon.com/images/I/81DzLU1-9ES.jpg) ## Frequently Bought Together - Spectra479 - Fit Over 99.9% Blue Light Blocking Glasses for Sleep - Amber Nighttime Eyewear - Turn your Prescription & Reading Glasses Into World-Class Blue Blockers - ViewJoy Sleep Glasses 99.9% Blue Light Glasses Dual AR Coatings Amber Orange Lens for Computer Gaming Reduce Eyestrain - Blue Blocking Amber Glasses for Sleep 99.9 Percent Effective - Nighttime Eye Wear - Special Orange Tinted Glasses Help You Relax Your Eyes --- ## 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.sk/products/186348153-fit-over-amber-blue-light-blocking-sleep-glasses-for-prescription](https://www.desertcart.sk/products/186348153-fit-over-amber-blue-light-blocking-sleep-glasses-for-prescription) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-10-24*
