Just put on my TrueDark Twilight optical filters about five minutes ago. When I wear these before bed, I can often double my deep sleep. It is a very different effect than I got from old fashioned blue blockers because there are colors other than blue that tell your brain to stay awake. The research that led to these glasses is patented! I'm pretty sure they are not Victoria's Secret approved, but I like to wear them to bed anyway, and so does Lana. ?? #sleep #biohacking #dreams #circadian
