I have been wearing contacts for 17 years. The disposables are the way to go. They are supposed to be discarded after 2 weeks but I can get 3 months out of them. I take them out every night and use the No Rub solutions to clean them.

On the bike I had to use sunglasses that wrap around (like Oakleys) to keep the wind from blowing directly into my eyes and drying and irritating the contacts. I always used polarized lenses in my sunglasses as you can see so much better. Good idea to keep a little eye juice with you just in case.
