It's not a pretty thing.
I had that happen to me in London about 15 years ago there was a building site with a lot of sand and cement blowing about and it got under my lens. Having the gas permeable I was able to take it out and wash and put it back but having friends who have the soft lens that must not get any water on them it must be a nightmare and I suppose you have to take solution with you all the time. Though I suppose most people have the disposable ones so a spare set goes with you now I guess.
