## Description

Product Description

Review: 目の疲れが軽減！PC作業が快適になりました - PC作業やスマホを見る時間が長いため購入しました。装着すると目の疲れが軽減され、長時間の作業でも以前より楽に感じます。ブルーライト対策として満足しています。 一方で、フレームはやや重めなので、長時間装着していると鼻に負担を感じることがあります。その点以外は満足しており、目の疲れが気になる方にはおすすめです。
Review: Best - The best on the market. Comfy and flexible enough for an adult head as opposed to the cheap Chinese ones. My old pair lasted a decade.

## 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.

## 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.

The best on the market. Comfy and flexible enough for an adult head as opposed to the cheap Chinese ones. My old pair lasted a decade.

### ⭐⭐⭐⭐⭐ They actually work
*by M***R on 24 July 2021*

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.
