I wear big ol' over-glasses that cover my glasses, and half my face. I love them because they keep the sun, wind, and hard, painful things like bugs and dust out of the eyes. I've seen wasps fly directly into the lens of these puppies at 25 mph, bounce off and fly merrily along their way. Probably would have gotten stung in (or at least too close to) the eye if not for these big over-glasses. Looks sorta dorky but I don't care.

Very much like these, only with darker lenses:



I won't leave home without them any more, I love them that much. Cheap, too, so I don't have to worry about them getting lost or broken.
