Unlike standard blue blockers that only filter some blue wavelengths, TrueDark's patented technology blocks ALL sleep-disrupting light frequencies (blue, green, and violet) between 380-500nm, functioning like noise-canceling headphones for your eyes. Your eyes contain specialized melanopsin photoreceptors that signal your brain when it's daytime, suppressing melatonin production. TrueDark Twilight Glasses effectively block these disruptive wavelengths, allowing your body to produce melatonin naturally. The result? You'll fall asleep faster and enjoy deeper, more restorative sleep—even after evening screen time. Featuring prescription-grade polycarbonate lenses with scratch-resistant coating, TrueDark Twilights are designed for comfort with lightweight, durable frames and spring hinges for a personalized fit. Each style in the Twilights collection offers the same powerful sleep-enhancing technology in various fashionable designs to suit your personal style. For optimal results, simply wear your Twilights 30-60 minutes before bedtime while watching TV, checking emails, or browsing on your phone. Perfect for night owls, shift workers, frequent travelers battling jet lag, or anyone wanting to improve sleep quality without giving up evening screen time. Transform your sleep and optimize your health with TrueDark Twilight Glasses—because when you sleep better, you live better. Note: For indoor use only. Not suitable for driving or outdoor activities at night.
