Improved frame- now with flexible arms! TrueDark works so well that users often fall asleep in the glasses! To increase comfort and reduce breakage, the arms are now flexible.

If you use electronics (phone/tablet/laptop) in bed to read this style is the ideal choice. If you read a paper book with a lamp in bed, you might want to consider TrueDark® Twilights Elites instead.

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 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 accessed.

When you wear your Twilights for as little as 30 minutes before bed, you help to prevent your melanopsin from detecting the wrong wavelengths of light at the wrong time of day. This can support your circadian rhythm and can help you fall asleep faster and get more restorative and restful sleep.

Stop Junk Light with TrueDark® Twilights technology that aims to free your hormones and neurotransmitters to do their best work. Twilights Classic aim to: 

  • 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. Twilight Classic aims to offer true clarity of light and consistent junk light coverage throughout the scratch-resistant lenses.


You can 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 mums) 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. They aim to block 100% of blue, green, and violet wavelengths. Choose these if you want maximum light blockage while at rest before bedtime. 

Combined with daytime use of TrueDark Daylights glasses, you’ll experience 24-hour protection from junk light. 

Do not drive or operate heavy machinery while wearing these glasses as you could become tired and your depth of perception and colours can change.
