My husband and i work at the colorado state fair every year . There is a vendor there that sells wrap around sun glasses. I buy my bike glasses for around 10-15 $. And a good thing too. I keep my glasses by my bike stuff in the garage (like most I am sure). Last halloween someone was using spary paint and sprayed my glasses. Then there has been the couple times bee's flew inside my lens, so of coarse I whipped my glasses off my face on to the ground (few scratches there) so me owning an expensive pair is not good. But I am telling you the one's I got from the fair are really nice. They look like I spent a lot. and they keep my eye's from watering too much.
So if these don't work out and you don't want to spend the big $ go to your local county fair and search out the eye glass vendor. They are at every fair.
