I used to wear contacts, by then my optometrist/opthalmologist told me I had to wear glasses for a while or I'd never wear contacts again (had a bunch of new, leaky blood vessels developing in my eyes). I used to ride w/contacts and sunglasses, now I just ride with my glasses. So far, no problems. They keep the wind and bugs out of my eyes, and I can see. Wrap arounds might be handy at speeds greater than 25-30mph or so (my glasses sometimes develop weird aerodynamics and start moving around at those speeds), but I don't spend a lot of time going that fast, so no worries.

I much preferred the contacts + sunglasses combo though. Better peripheral vision, better glare control, and I looked a (tiny) bit cooler
