FLATTERING ON ALL FACE SHAPES, THIS BLUE LIGHT BLOCKER IS HIGH-CHEEKBONE VINTAGE AT ITS FINEST.

Cat Eye Day Swannies has a rating of 4.9 stars based on 21 reviews.
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.
