Prepare for a great night’s sleep
By telling your body it’s dark with the dark red lenses on TrueDark® Human Compatible® Twilights Fitovers eyewear! You can still read, watch TV, or work on your computer/tablet/phone while your sleep hormones shift to night mode. When your head hits the pillow, you’ll fall asleep quickly and sleep more deeply.
Twilights glasses are also great for managing time-zone shifts, such as when traveling. Another great use is for people (such as new moms) who get up in the middle of the night and need to get back to sleep quickly. For those who live in far northern climates where it’s light well into the night, Twilights glasses can provide “early darkness” for better summertime sleep.
TrueDark® is designed to be worn 30 minutes to 2 hours before going to bed or wanting to sleep. 98% of blue, green, and violet wavelengths are blocked. Choose TrueDark® red lensed Twilights if you are still active around your home before bedtime (so you can see the dog or cat instead of tripping over them).
Combined with daytime use of TrueDark® Daylights™ glasses, you’ll experience 24-hour protection from junk light.
When the sun goes down, blue light isn’t the only junk light that can disrupt our sleep cycle, and more than blue blockers are needed. TrueDark® Twilights is the first and only solution designed to work with melanopsin, a protein in your eyes responsible for absorbing light and sending sleep/wake signals to your brain. Without melanopsin, melatonin can’t be released.
Wear your Twilights 30 minutes before bed to prevent your melanopsin from detecting the wrong wavelengths of light at the wrong time of day. This supports your circadian rhythm and helps you fall asleep faster and get more restorative and restful sleep.
Stop Junk Light® with TrueDark® Twilights technology that frees your hormones and neurotransmitters to do their best work.
- Block the harshest blue, violet, and green sleep robbing wavelengths emitted by fluorescent lights, LEDs, electronics, phones, tablets, and computers
- Support your evening and nighttime hormone levels
- Improve overall sleep
- Synchronize your circadian rhythm
The Twilights lenses are strategically designed based on research and technology that uses pure, durable, prescription-grade polycarbonate lenses. This results in true clarity of light and consistent junk light coverage throughout the scratch-resistant lenses.
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.

I have been using the Sleep Hacking Fitovers for over two weeks and my sleep has been amazing!
I bought these to replace some blue-blocking safety goggles that I bought on Amazon a couple of years ago after reading the “Sleep Smarter” book. These TrueDark glasses work much better to the point that I wonder if my old safety goggles were doing anything. It’s been like “night and day” how much better TrueDark works…excuse the pun!
Given their fit-over design, they fit well over my glasses and they block light around my face so I feel confident turning my head and looking around without blue light sneaking in. Great design and great results!
