## Description

desertcart.com: TrueDark Twilights Classic by Dave Asprey | For Deep Sleep | Deep Red Blue Light Blocking Glasses for Women & Men | Block 99% of Blue, Green & Violet Light for Night Use : Health & Household

Review: Fully block blue and green. - I don't see any blue or green LEDs on my appliances and other devices when wearing this glasses. I mean it's 100% block! Impressive. By the way, the other glasses of Dave Asprey don't do a full block, even lens color may seem the same.
Review: Absolute light blocking - This product follows the science of blocking out all wave lengths except red. I’ve tried many products and this is by far the most comfortable and has the least light leakage if any. I get drowsy as soon As I put them on. They are expensive but so is buying 5 cheap pairs that don’t work, leak, are uncomfortable etc. please keep supplying this product. It is required lifestyle medicine to make exogenous melatonin work properly in the body as a free radical scavenger, mitochondrial booster, and promoting senescence and oncostatic properties.

## Features

- Block all blue light, plus green and violet to mimic complete darkness. Perfect for: sleep struggles, travel, meditation, shift work, and hardcore recovery. Slip them on 30 minutes before bed — or anytime you need a biological reset. Not designed for screen use.
- Block 99% of blue, green, and violet light. Red lenses are engineered to filter all junklight wavelengths and mimic complete darkness, helping your brain shift into sleep-ready mode for faster, deeper rest.
- They signal one thing: time to shut off. Twilights are EEG-tested to shift brainwaves from wired (beta) to calm (alpha) and sleep-ready (delta), these are for people who want deep, fast, real sleep.
- Durable Frame Design: Lightweight sport-style polycarbonate frame with a full-coverage foam barrier and flexible TR90 arms. Frame Width 142mm | Lens 65mm x 40mm | Bridge 20mm | Arm 120mm. Built for maximum coverage and comfort, even while you sleep.
- 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: How are these different than Daylights and Sunsets? Can I wear TrueDark Twilights at any time of the day?**
A: Twilights are for nighttime (use 30 mins before sleep), to shift your brain into a calm, sleep-ready state. They can shift your circadian cycle and help you beat jetlag. Using Twilights during the day may block wavelengths needed for focus & energy.

**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 Twilights glasses to block junklight?**
A: Wear 30 minutes before bed and anytime you may wake during the night. If you wake for any reason (to get a drink, bathroom break, or childcare), Twilights protect your circadian rhythm so you can fall back asleep quickly.

**Q: What are other good times to use Twilights glasses?**
A: Twilights are especially helpful for shift workers, frequent flyers, and anyone struggling with sleep. By simulating total darkness, they’re an effective tool against jet lag and irregular sleep schedules.
