FLATTERING ON ALL FACE SHAPES, THIS BLUE LIGHT BLOCKER IS HIGH-CHEEKBONE VINTAGE AT ITS FINEST.
Swanwick's Cat Eye Day Swannies are like walking off the set of Breakfast at Tiffany's.

Swannies are the blue light blocking glasses that actually work.
Youll find most clear-lens blue blockers on the market only block blue light up to 420nm.
Day Swannies lens technology, however, blocks 98% of blue light at 400 nanometers, graduating to 45% at 450nm, and 21-45% of blue light between 450-500nm.
This proprietary blend of blue light blocking provides you the optimal conditions for peak performance all day long.

Why are Day Swannies clear?
The almost-clear lens is for daytime screen-time.
They block the blue 400-450nm wavelength range, shown to be most harmful of the spectrum, while allowing healthy light.
