Hard or soft contacts? I wear soft contacts and have never had any issues with them regardless of the temperature. The only time I have had trouble with them was on a motorcycle traveling at a high rate of speed. Thus I suggest you go to a motorcycle dealer and pick up a set of motorcycle sun glasses that have the removable lenses. Wear the clear lenses in the morning when it's dark, and whatever shade you prefer at night. They look just like a set of Oakley’s and have a foam insert on the inside of the lens frame that presses up against your eye socket effectively sealing out the majority of the outside air.
Hope this helps!
