Ewwww....contacts?! You mean...sticking ym fingers into my eye! Eep!

Glasses here. Even if I wasn't just plain chicken, contacts would be prohibitively expensive for me since I wear progressives and have bad astigmatism.

I never thought to tie the tearing up thing with my glasses though... I was thinking about wearing my lab goggles just to keep the wind out of my eyes somewhat (Okay, so I'd look like Bill Nye the Science Guy, but man is it ever windy here), but now I'm wondering if the vents would just make it worse...

For the OP, for your next pair of glasses, you might think about getting a set of titanium frames from 39dollareyeglasses.com. I absolutely love mine, they are so light and strong. They have much cheaper frames, but with a toddler ti sounds like it might be the way to go! (Too bad I can't have a matching bike )
