## Questions & Answers

**Q: Will TrueDark Daylights glasses help with migraines or light sensitivity?**
A: Many users with photophobia or light-triggered headaches find relief by reducing exposure to fatigue-causing wavelengths from screens and artificial lighting. Daylights Aviators transition into sunglasses for outdoor use providing UV400 protection.

**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 Daylights glasses to block junklight?**
A: Wear Daylights after getting some natural sunlight in the morning. Aim for about 30 minutes of daylight first—then use Daylights to block junklight from screens, LEDs, CFLs, and other artificial sources throughout the day.

**Q: What percentage of blue light should I be blocking during the day?**
A: Your brain needs some blue wavelengths during the day to stay alert and energized. TrueDark Daylights target only the disruptive wavelengths (380–500nm), while still letting in the beneficial light that supports focus, mood, and energy.
