Frequently Asked Questions
Why Blue
Light Matters
Blue light isn’t inherently harmful—during the day, it helps regulate our sleep-wake cycles and keeps us alert. But prolonged exposure to artificial blue light, especially after sunset, tricks the brain into staying awake by suppressing melatonin production. This disrupts your body’s natural sleep-wake rhythm (circadian biology), increases cortisol levels, and places chronic stress on your nervous and hormonal systems.

Designed for all-day wear, our frames are crafted for comfort and durability—never bulky, always breathable. Whether you’re on a Zoom call or out at dinner, they pair easily with your lifestyle.


Filters up to 100% of harmful blue and green light
Depending on the lens type, Cellf Blue Blockers can block nearly all disruptive blue (400–495nm) and even green (up to 550nm) wavelengths—the same spectrum shown in studies to suppress melatonin and delay sleep.
