What's the difference between the yellow and red lenses — which one should I use?
Yellow lenses filter moderate blue light from screens and artificial lighting, reducing eye strain during your daily routine without affecting alertness.
Red lenses are for nighttime — they block ~95% of sleep-disrupting blue and green light, allowing your brain to naturally produce melatonin and prepare your body for deep, restorative sleep. Wear them 2–3 hours before bed.
