These glases are so good, and the design is clean and robust as well. 10/10. will recommend this. They came in 1week before as well. Review: Brace yourself - If you have used cheap blocking glasses in the past - brace yourself. These are seriously next level. Yes, they are quite spendy but wow. You know those blue indicator lights on things like washing machines etc? Yeah - I put these on and those completely disappear. I will say that watching something online with these on is a bit 'different' because of the spectrum blocking. Oh well. These are also comfortable to wear, and the sides block out stray light well. Highly recommend. TrueDark's are what other blocking glasses wish they were. ## Features - Block all blue light, plus green and violet to mimic complete darkness.

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 ### ⭐⭐⭐⭐⭐ If u want to win, buy these glasses *by A***D on August 4, 2026* Amazing. These glases are so good, and the design is clean and robust as well. 10/10. will recommend this. They came in 1week before as well. ### ⭐⭐⭐⭐⭐ Brace yourself *by C***M on October 28, 2025* If you have used cheap blocking glasses in the past - brace yourself. These are seriously next level. Yes, they are quite spendy but wow. You know those blue indicator lights on things like washing machines etc? Yeah - I put these on and those completely disappear. I will say that watching something online with these on is a bit 'different' because of the spectrum blocking. Oh well. These are also comfortable to wear, and the sides block out stray light well. Highly recommend. TrueDark's are what other blocking glasses wish they were. ### ⭐ Wide fit and extremely low quality materials *by P***T on June 23, 2026* Overall: Extreme cheap product quality better priced at $20. A different Amazon vendor sells the same frame with the same lenses for 50% less. Search for safetey blue sleep savior. RETURNED IMMEDIATELY AFTER OPENING. The frames: These are easily the lowest quality glasses frames I have ever seen or owned. It is an extremely light weight and brittle plastic. If you fell asleep on these, dropped them, or accidentally rolled over on them, they would definitely break. Feels like foamed ABS plastic - think 1980s car interior. The Lens: The lens is a very deep red which likely blocks the advertised spectrums. The lens is relatively thin and doesn't distort vision. It does reduce light transmission on all spectrums pretty strongly, so note that using in very low light or the dark is likely not safe. The Fit The frame is made for wider heads than mine. While brand name sunglasses fit with no issue, these are wide enough that the foam didn't seal against my face at all. While the cheap plastic is very light, the plus is you likely forget you're wearing them (other than the deep red hue that everything takes on). ## 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.tn/products/49476081-truedark-by-dave-asprey-twilights-red-lenses-block-99-blue](https://www.desertcart.tn/products/49476081-truedark-by-dave-asprey-twilights-red-lenses-block-99-blue) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-20*
