I wear a pair of Oakley glasses that have a prescription insert that sits
behind the outer "shield" lense. I can just do without on foggy days,
but
I've heard of people using a product called Rain-X on their outer lenses.
I've used it on my car windshield and it's incredible. It just makes
water
repel like crazy. Look for it at an auto parts store or at Wal-Mart.

Rain-X used to have a caution on the bottle to not use it on plastics.

I find a visor helps a lot to keep mist and drizzle off of my glasses.
