Block all blue light, plus green and violet to mimic complete darkness.

Twilight lenses go all in, these were deigned to put you to sleep within 30 minutes of use — blocking 99% of blue, green, and violet light. They signal one thing: time to shut off. Twilights are EEG-tested to shift brainwaves from wired (beta) to calm (alpha) and sleep-ready (delta), these are for people who want deep, fast, real sleep. Slip them on 30 minutes before bed — or anytime you need a biological reset. 

Perfect for: sleep struggles, travel, meditation, shift work, and hardcore recovery.
