How to Use TrueDark™ Twilight Glasses

TrueDark™ Twilight glasses contain patented lenses that provide your eyes and brain with virtual darkness. They are most effective at night before going to sleep.

TrueDark Twilight glasses come in multiple styles. Most are designed to be used straight out of their box. Simply remove the protective packing material and begin wearing anytime within about 30 minutes before you want to go to sleep. A removable prescription insert is included as part of the Twilight Classic style. See instructions below.

When to Wear TrueDark™ Twilight Glasses

Experiment to see how your body and sleep patterns react to Twilight glasses. We suggest initially using them approximately 30 minutes prior to going to sleep. Some people find that a shorter time frame works for them. Others find amazing benefit and maximum impact from wearing the glasses as much as 2 hours before they want to fall asleep. There is no one-size-fits-all solution here, so find what works best for you! 

Pro-tip: Wear your TrueDark™ Twilight glasses during air travel, especially during nighttime flights when you expect to land in the morning at local time. Avoid taking the glasses on and off repeatedly as multiple major shifts in light right before bedtime can cause melanopsin activation (melatonin suppression) and physiological stress.

Caution: Avoid using TrueDark™ Twilight glasses if you are working at night or concentrating deeply.Instead, use TrueDark™ Daywalker while you’re concentrating, then switch to TrueDark Twilight™ when you’re done.
