I wear soft contacts and have never had a particular problem.

If you take a contact out and it dries out, it is possible to rehydrate it. Had to do it once on a business trip where I dropped a contact outside of the storage case by accident and it dried up overnight. I carefully put it in the case and filled it with solution and the lens rehydrated and I was able to wear it (and it was comfortable too!). I don' recommend it, but it works in a pinch.
