Excellent, thanks for all your replies. I'll try out some plans to keep my contacts in, but i think i will most likely be going with the prescription sport glasses. I found a groupon deal that can be applied to prescription oakleys and project rudy. But those Tifosi podiums seem to be a great deal, especially if you get them from REI.

I am getting gear ready for a tour divide attempt and I am curious as to what people do about glasses/contacts during such a long ride. I am thinking about going with prescription oakleys. But Im not sure if they have a frame that can take interchangeable lenses (I would need a clear lens to see at night).

I would be interested to hear what people have tried. I am leaning away from contacts for the simple fact i dont like to sleep in them, and I am worried about keeping my hands clean enough to change them everyday.

Thanks for any input.
