Annie:

I do have wraparound sunglasses. Maybe they aren't tight enough, but I think its just the lack of humidity here in the desert. Today, for example, its getting ready to rain and the humidity has climbed from 10% to 18%-it's almost high enough that your lungs don't feel like they're getting fried when you take a breath!

After reading your post, I hit the clearance sales at my favorite bike shops today and found a pair of kid's sunglasses that fit more snug. The quality is kind of dubious, but hey for $6.99 (marked down from like $55) I'll give them a shot.
