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 is now available with progressive sun lenses. With this style, we've gone underground. We now communicate in Morse Code. For those of you picking up what we're putting down, the messages will continue to flow. Maintain radio contact. I read you Houston, and come in Tokyo.



  • See near and far with the one pair of Sunglass readers.
  • Consider these a stop-stacking-your-glasses-on-your-head solution.
  • See your book and the beach. Fix a flat and see the trail. Take that sunshine and tiny text.
  • Featuring high grade, progressive lens. Yes progressive.
  • The progressive lens means that noone knows you're wearing readers. The high quality sun lenses protect your eyes from harmful UV light and help to relax your eyes while looking up close.


Like our clear lens Progressives, our sunglasses progress from no magnification at the top to your chosen magnification at the bottom. Hence the name.

  • An innovative no-line lens
  • 100% UV protection 
  • Blue light protection

These are not tint-transitioning lenses.  They are always sunglasses.
