Twilights Fitovers

Twilights are generally for nighttime use. Wearing them consistently during the day would block the healthy light your brain needs to stay energized and focused. There are instances where you can use these glasses to shift your circadian cycle, like if you are traveling to a different time zone. TrueDark Twilights are great for hacking jetlag. They can also help night shift workers fall asleep more easily, as they emulate complete darkness. EEG data shows TrueDark glasses can shift your brain into a calm, sleep-ready state within minutes.

Twilights deliver maximum nighttime protection. They block 99% of blue, green, and violet light, mimicking complete darkness to tell your brain it’s time to sleep. Sunsets block slightly less so you can still perform evening tasks while transitioning into rest.

Yes. Each lens plays a unique role in the full system. 

Daylights filter 75% of blue light, protecting you from screens and overhead lighting while still letting in the healthy blue you need for daytime energy and focus. 

Sunsets use a gradient lens that blocks 93% of blue & violet and 99% of green light. The darker red top shields you from harsh overheads, while the lighter yellow bottom keeps vision clear for evening tasks. 

Twilights go further, blocking 99% of blue, green, and violet light. EEG testing shows they shift your brainwaves into a rested state within minutes, helping you fall asleep faster and stay asleep longer. 

Together, Daylights keep you sharp, Sunsets ease you into rest, and Twilights deliver deep, restorative sleep. 

Junk light is the artificial light blasting from screens, LEDs, and overheads at the wrong time of day. Your brain treats light like a signal—and junk light sends the wrong one. It tells your body “it’s still daytime,” even late at night. The result? Junk sleep, junk energy, junk focus, and a biology that’s constantly out of rhythm.

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.

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.

No. Twilights are designed to block the harshest junklight while still allowing enough safe visibility for nighttime tasks. You’ll be able to move around comfortably without overstimulating your brain.

Important Note: Do not drive or operate heavy machinery while wearing. Avoid activities that may be impacted by becoming tired, a change in depth perception, or changes on the color spectrum.
