Named after the German word for “time giver,” the environmental cues that set your internal clock, Zeitgeber is the original Cadian frame and the one that started it all. With Day Lenses, Zeitgeber is built for long hours in front of screens. It filters harsh blue light from monitors and overhead lighting to help reduce eye strain, fatigue, and headaches, so you stay focused and calm through the workday, whether you’re at the office, studying, or deep in a screen-heavy project. With Night Lenses, it blocks 100% of the blue and green light that disrupts your sleep cycle, so you can watch TV, scroll your phone, or unwind after a long day while your body naturally prepares for rest. Lightweight, scratch-resistant, and made for all-day wear, Zeitgeber is the classic that keeps your rhythm in sync from morning to night.
