I wear contacts, and take them on backpack hunts. Mine are actually extended wear, but they bother me if I don't take them out each night. It's a pain when backpacking but it's the best solution I have, short of Lasik. I have observed that while glassing, my bino's or spotter fog up quite quickly from my eyes, and I wonder if the contacts are exacerbating that...
You will need a contact prescription. Once you find some that work well for you I'd stock up, as your prescription is only good for a year.
