SUPERIOR BLUE LIGHT BLOCKING DAY LENSES IN OUR BEAUTIFULLY CRAFTED CRYSTAL FRAMES.

Swanwick's Crystal Day Swannies are tough to beat on the fashion front! Originally launched on Indiegogo, these Day Swannies remain at the top of our bestsellers list month after month. You'll block the bad blue light from phones, tablets, and computers while attracting compliments like never before. You’ll find most clear-lens blue blockers on the market only block blue light up to 420nm. Day Swannies, however, block 98% of blue light at 400 nanometers, graduating to 45% at 450nm, and 21-45% of blue light between 450-500nm. This blend of blue light blocking ensures you the optimal conditions for performing your best all day long.
