Their frames are unique, durable, and built for self expression. You'll find a pair in every room of our founder Jenna Cooper's home. The Root Cause Analysis is a full acetate aviator with a keyhole bridge in gloss black. Polarized grey lenses enhance contrast and reduce 99. 9% of glare without digital screen distortion.
