Swanwick's Cat Eye Day Swannies are like walking off the set of Breakfast at Tiffany's. With the unmistakable Swannies finish, these retro blue blockers bring a classic feline flair and don't skimp on anything for style. Swannies are the blue light blocking glasses that actually work. You’ll 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.
