Comfy and flexible enough for an adult head as opposed to the cheap Chinese ones. My old pair lasted a decade. Review: They actually work - I wasn't sure they would work as I suffer from headaches and dizziness when working at a screen all day and I also struggle to focus, these have solved all 3 ussues however for the first week I did get some random headaches but they stopped after the first week. I would recommend these glasses however they are not to be used outside. A game changer and i am grateful for ones that actually work. ## Features - Block the harshest blue light wavelengths emitted by LEDs, electronics, phones, tablets and computers - Reduce daytime eye strain by blocking 40% of blue light; great for reading, gaming, TV - Improve overall sleep & synchronize your circadian rhythm - Anti-reflective coating on scratch resistant lenses reduces glare and helps filter blue light - Lightweight full coverage daytime blue blockers that fit over prescription glasses for men or women ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07GRCCN68 | | Best Sellers Rank | #134,402 in Health ( See Top 100 in Health ) #1,282 in Reading Glasses | | Customer reviews | 4.4 4.4 out of 5 stars (77) | | Date First Available | 5 September 2018 | | Department | unisex-adult | | Is Discontinued By Manufacturer | No | | Manufacturer | Truedark | | Package Dimensions | 17.91 x 6.91 x 6.6 cm; 158.76 g | ## Images ![TrueDark by Dave Asprey | Daylights Yellow Lenses Block 75% of Blue Light for Heavy Daytime Screen Use - Image 1](https://m.media-amazon.com/images/I/31VSmLKeElL.jpg) ![TrueDark by Dave Asprey | Daylights Yellow Lenses Block 75% of Blue Light for Heavy Daytime Screen Use - Image 2](https://m.media-amazon.com/images/I/51ZuqUAYx7L.jpg) ![TrueDark by Dave Asprey | Daylights Yellow Lenses Block 75% of Blue Light for Heavy Daytime Screen Use - Image 3](https://m.media-amazon.com/images/I/412lBucrVgL.jpg) ![TrueDark by Dave Asprey | Daylights Yellow Lenses Block 75% of Blue Light for Heavy Daytime Screen Use - Image 4](https://m.media-amazon.com/images/I/51UTTRlkFdL.jpg) ![TrueDark by Dave Asprey | Daylights Yellow Lenses Block 75% of Blue Light for Heavy Daytime Screen Use - Image 5](https://m.media-amazon.com/images/I/4143fEFflTL.jpg) ## Available Options This product comes in different **Lens Color, Color** options. ## Questions & Answers **Q: Will TrueDark Daylights glasses help with migraines or light sensitivity?** A: Many users with photophobia or light-triggered headaches find relief by reducing exposure to fatigue-causing wavelengths from screens and artificial lighting. Polarized lenses reduce glare and UVA/B filter provides additional protection. **Q: Do I still need Sunsets or Twilights if I wear Daylights junklight blocking glasses all day?** A: Yes. Each lens plays a unique role. Daylights filter 75% of blue light while letting in healthy blue for energy and focus. Sunsets help you ease naturally into evening, and Twilights block 99% of junklight to mimic darkness and support deep sleep. **Q: What is Junklight and how can it affect me?** A: Junklight is the artificial light from screens, LEDs, and overhead lighting. Your brain treats light like a signal—the wrong light at the wrong time of day throws your biology out of rhythm. The result? Junk sleep, junk energy, junk focus. **Q: When is the best time to use Daylights glasses to block junklight?** A: Wear Daylights after getting some natural sunlight in the morning. Aim for about 30 minutes of daylight first—then use Daylights to block junklight from screens, LEDs, CFLs, and other artificial sources throughout the day. **Q: What percentage of blue light should I be blocking during the day?** A: Your brain needs some blue wavelengths during the day to stay alert and energized. TrueDark Daylights target only the disruptive wavelengths (380–500nm), while still letting in the beneficial light that supports focus, mood, and energy. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best *by A***S on 2 December 2025* The best on the market.
