This is why you ALWAYS wear sunglasses fishing. Especially if you're chucking big, nasty streamers like this one. It's up to you if the lenses are glass or plastic. In my opinion you catch more fish with glass, but I would say plastic is more safe.
Deeter my friend, you had better watch yourself these coming months. It's slowly turning fall and I'll be switching out my nymph rigs for gaudy bait fish patterns. Go ahead, continue to throw your dainty dry flies. I'll be poaching your runs and holes with what fish really want to eat. So watch my backcast as I wouldn't want you to literally feel solied when one of these babies whizzes by your face.
