How are these different than Daylights and Sunsets? Can I wear TrueDark Twilights at any time of the day?

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.

Do I still need Sunsets or Twilights if I wear Daylights junklight blocking glasses all day?

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.

What is Junklight and how can it affect me?

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.

When is the best time to use Twilights glasses to block junklight?

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.

What are other good times to use Twilights glasses?

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.
