Blue light isn’t the only problem

A full spectrum of Junklight—including violet and green wavelengths from phones, laptops, LEDs, and artificial light—trigger the same negative reactions as harmful blue. The headaches, fatigue, difficulty falling asleep—until you block all junklight, you're running at a biological disadvantage.

TrueDark is the original, EEG-tested, science-backed light protocol.  Block junklight. Reset your rhythm. Feel like yourself again.

    EEG-TESTED* BRAINWAVE SHIFTS

    The only brand with an EEG verified study that shows Twilights shift brainwaves from wired beta to calm alpha or deep sleep delta.

    PRECISION LIGHT TARGETING

    Each lens filters the specific wavelengths of harmful junklight (blue, green, and violet) emitted from screens, LEDS, and artificial light.

    ORIGINAL CIRCADIAN LENS SYSTEM

    Designed as a 3-lens protocol: Daylights, Sunsets, and Twilights. Each lines up with how your biology responds to light across the day.
