The Root Cause Analysis is a high density acetate frame, which means it’s created from the good, expensive stuff. The time tested aviator shape originates back to a date of which the Internets is just not letting up that easily…but trust us when Caddis says, “timeless”. Sidebar: Given the amount of hater comments regarding the words engraved across the tops of some of Caddis' frames, they’ve gone underground. They now communicate in Morse Code. For those of you picking up what Caddis is putting down…the messages will continue to flow. Maintain radio contact. I read you Houston…and come in Tokyo.

All Caddis frames feature their proprietary blue light blocking lenses at no extra cost to you:
