I've had Oakleys for years and ended up buying 3rd party lenses for all of them as they have been discontinued. The problem I always run into with third party lenses is how thin they are and they are no different. They are very thin, appear brittle, allow the flame to bend too much, and make cheap noise, all because of their thinness. Strong as a nail I don't think; The only pros I can think of are polarization and color. For those wondering, I finally found some good third party thick lenses from a company called Tintart. They even etch the lenses to look like the originals.
