I always fish with polarized sunglasses. I have seen a couple guys catch split shot and sinkers in the eye, and one guy ended up losing his sight from it. His line was hooked on some bed rock, gave it the old heave ho, and it was like a 22 bullet going right at his eye. The lenses on the glasses would have slowed it down enough for him to be OK. It's a fact, as my glasses saved me from the same thing a couple years ago. Fishin is fun, but not worth losing your eye sight over.
