Your eyes have special cells filled with a very light-sensitive protein called melanopsin. These cells signal to your brain that it’s daytime when they are exposed to certain wavelengths of light. This causes your brain to stop producing hormones, such as melatonin, that are essential to having a restful and productive night of sleep. Traditional blue blockers are good at filtering out blue light, but it’s not only blue light that affects your sleep. Spectrums between the colors of yellow and purple can interfere with the melanopsin in your eyes and make it very hard to fall asleep properly. This is why staring at a computer screen or phone before bed can interfere with your sleep!TrueDark Twilight glasses are the first and only glasses designed specifically with multi-layer optical filters that block ALL of the sleep and performance robbing wavelengths in the evening hours. #StopJunkLight with TrueDark Twilight technology that frees your hormones and neurotransmitters to do their best work. Twilight glasses feature a wrap-around sport frame with comfortable foam padding around the eyes to help prevent extra light from seeping into the sides and top. They allow you to see, read, watch TV and do other household activities while simultaneously tricking your brain into thinking it’s completely dark. This causes your brain to start getting ready for bed, which can help you fall asleep faster and have a more rejuvenating and productive night’s rest. They are great for treating jet lag, too! This product is for indoor use only. ## Features - NEWLY IMPROVED! Improved frame- now with flexible arms! TrueDark works so well that users often fall asleep in the glasses! To increase comfort and reduce breakage, the arms are now flexible. - Improves sleep quality - maximizes control of your circadian rhythm.

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 A***H on 11 December 2025* ### ⭐⭐⭐⭐⭐ Review *by F***A on 11 March 2024* ### ⭐⭐⭐⭐⭐ Review *by H***K on 6 March 2026* ## 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.co.uk/products/348395303-twilight-classic-sleep-hacking-blue-green-violet-light-blocking-glasses](https://www.desertcart.co.uk/products/348395303-twilight-classic-sleep-hacking-blue-green-violet-light-blocking-glasses) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-19*
