When you sleep better, you feel and live better. TrueDark sleephacking tools allow you to take control the junk light in your environment, which is a prerequisute for better sleep, increased energy, focus and clarity. When you’re surrounded by junk light during waking hours, use our Daywalker glasses to filter out the right amount of blue light — not too much, but enough to still keep you alert during the day. This is an improvement on traditional “blue blockers” that filter out all blue light, even when you need some. Alternatively, use our Twilight glasses at home when you’re getting ready to go to bed. These block all sleep-stealing light — signaling your brain that it’s time for sleep. You can also cover or reduce the junk light from artificial light sources around your home or office with TrueDark Shields.
