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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by H***K on March 6, 2026* ### ⭐⭐⭐⭐⭐ Review *by C***M on October 28, 2025* ### ⭐⭐⭐⭐ Review *by J***R on December 25, 2024* ## Frequently Bought Together - TrueDark Twilights Classic Blue Light Blocking Glasses - Reduce Eye Strain and UV Glare for Better Sleep - Men & Women - Computer Screen, Gaming, TV, Phone - by Dave Asprey - Blue Blocking Amber Glasses for Sleep 99.9 Percent Effective - Nighttime Eye Wear - Special Orange Tinted Glasses Help You Relax Your Eyes - Infield Terminator UV-400 Safety Glasses for Blue Light and UV --- ## 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.vn/products/49476081-truedark-by-dave-asprey-twilights-red-lenses-block-99-blue](https://www.desertcart.vn/products/49476081-truedark-by-dave-asprey-twilights-red-lenses-block-99-blue) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-16*
