Any screen fatigue has greatly reduced. And the glasses also look really cool, tbh. Review: A good investment in your health. - I was surprised by how remarkably well these glasses worked. The effect was immediate and I noticed a significant reduction of eye fatigue while working on my computer. The frame is also of good quality, which I appreciate. I am a shift worker by trade and I am excited to see how these will work in combination with the twilight glasses (of which I also purchased a pair) in helping to blunt the effect of bright florescent lighting/computers/headlights at night on my circadian rhythm. I can definitely say that I notice a bit of a, for lack of a better term, "head change" while wearing them. I would describe it as a similar to being outdoors as the sun goes down and the environment transitions to the dark of night. Kind of a slight drowsiness. Just my subjective experience, and it goes away as soon as I remove them under florescent lighting. I'm certainly going to log more time with them before I consider whether or not to drive with them on.. I have had my eyes on these for several months (pun intended), but was hesitant due to the price. The reduction in eye fatigue while working on a computer screen was worth the price alone. I'm wearing them even as I write this review. ## Features - Block the blue light that disrupts focus and sleep. Perfect for: screen time, grocery runs, airports, and long workdays under LED and CFL lighting. - Block 75% of junklight indoors, and 99% of UVA/UVB rays. Engineered to filter fatigue-causing wavelengths and let in the energizing light your brain needs to promote daytime alertness. - Reduce Eye Strain & Support Focus: Reduces eye strain from long hours on screens while minimizing discomfort and sensitivity to artificial light. Supports lasting focus, less daytime fatigue, and encourages a natural balanced circadian rhythm for steady daytime clarity and better sleep. - Durable Frame Design: Lightweight aircraft-grade aluminum frame with spring hinges and polarized lenses that reduce glare without distorting natural light. Frame Width 156mm | Lens 63mm x 37mm | Bridge 14mm | Arm 126mm. Built for comfort, quality, and everyday wear. - Founded by Dave Asprey: TrueDark started from one problem: artificial light was wrecking Dave’s sleep. Cheap blue blockers weren’t cutting it. So the first ever lens system was built—using neuroscience, circadian biology, and decades of biohacking insight. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07262NGHN | | Best Sellers Rank | #194,799 in Health & Household ( See Top 100 in Health & Household ) #802 in Computer Blue Light Blocking Glasses | | Customer Reviews | 4.3 4.3 out of 5 stars (158) | | Date First Available | May 30, 2017 | | Department | unisex-adult | | Is Discontinued By Manufacturer | No | | Item Weight | 9.6 ounces | | Manufacturer | Biohacked | | Package Dimensions | 6.81 x 3.19 x 2.8 inches | ## Images ![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/51TiShaXr1L.jpg) ## 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 ### ⭐⭐⭐⭐⭐ Effective & Fashionable *by S***R on February 9, 2026* I've been using these for a year now whenever I spend more than a few minutes with screens.
