TrueDark Twilights Classic - Sleep-Enhancing Red Lens Blue Light Blocking Glasses - Blocks 99% Blue, Green and Violet Light for Better Sleep - Flexible Frame for Men & Women

TrueDark Twilight glasses are like noise-cancelling headphones for your eyes! Your eyes have special cells filled with a light-sensitive protein called melanopsin. These cells signal to your brain that it's daytime when exposed to certain wavelengths of light. This causes your brain to stop producing hormones, such as melatonin, that are essential to having a restful and productive night of sleep. (Studies show that reduced or blocked blue/green/violet light exposure triggers the release melanopsin into the body which starts melatonin production.)

Traditional blue blockers are good at filtering out blue light, but it's not only blue light that affects your sleep. This is why staring at a blue light emitting computer screen or phone before bed can interfere with your sleep!

TrueDark Twilight glasses are the first and only glasses designed to block ALL of the sleep robbing wavelengths in the evening hours. Twilight technology that frees your hormones and neurotransmitters to do their best work. (Twilight Classics offer our darkest red lenses for optimal melatonin production to activate sleep. Best before bedtime or times of low-activity.  Try Twilight Sunsets or Twilight Elites if performing tasks that require greater visibility.)

Twilight glasses feature a wrap-around sport frame with comfortable foam padding around the eyes to help prevent extra light from seeping into the sides and top. They allow you to do some household activities while simultaneously tricking your brain into thinking it's completely dark. This causes your brain to prepare for bed, which can help you fall asleep faster and have a more rejuvenating and productive night's rest. They're great for treating jet lag, too! (Light penetration depends on facial contours and fit. The light direction that matters most to inhibiting melatonin production is the light coming directly in to the lenses.)
