TrueDark on The Human Upgrade with Dave Asprey

Artificial light, also known as junk light, is one of the biggest threats to your biology today. Every photon of light that hits your eyes is sending a signal directly to your brain. That message tells your body what time it is. It influences hormone production, energy levels, alertness, recovery, metabolism and sleep. Light is information that your body uses to regulate itself every single day. The problem is that your body evolved under sunlight during the day, darkness at night, and very little in between. Now we spend our lives under LEDs, computer screens, televisions, fluorescent lights, and bright indoor environments that never turn off. Your brain receives those signals, whether you realize it or not. At 10 o'clock at night, your body may be exhausted, but the light entering your eyes is still telling your brain that it's the middle of the day. Your melatonin drops and your cortisol stays elevated. You're tired, but you can't ease into calm. Your brain is getting the wrong signal and your whole body feels it. That's exactly why I created Aegis. My signature frame from True Dark took a year of obsessing over every detail. Full titanium for all-day comfort, foldable side shields that block peripheral junk light from every angle, a frame that supports your circadian rhythm from the moment you wake up until the moment you go to sleep. Aegis is available in all three TrueDark lens options, so you can match the lens to the signal you want to send your brain throughout the day. Daylights filter artificial blue light during the day while still allowing the light you want for focus, alertness, and productivity. Sunsets block more blue, violet, and green light in the evening helping your brain recognize that the day is coming to an end so you can start shifting into recovery mode. Twilights provide the highest level of protection by blocking 99% of blue, green, and violet light before bed. This tells your brain that it's time to sleep. Three lenses, one frame, and a complete circadian protocol for your whole day. Once you understand that light is information, you cannot unlearn it. Aegis is at truedark.com.
