## 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.
