Some people like to ride through trees. When you follow a friend through the trees, a branch can have a whipping effect. First person pushes, and it comes whipping back at the second person. If your face smacks a branch and it can shatter the lenses.
Long story short, I visited this local board shop, and some guy apparently fell really bad and the goggle lenses shattered in his eyes. (they were a big name goggle company)

we all switched to oakleys afterwards.
