Try disposable contacts. I wear them for sports only (although I used to wear contacts for years) - they are fairly cheap per shot.

I've had two minor problems, but they are bearable:

Sometimes one turns inside out. It will not fit right and I have lost one right out of my eye on a descent when tears lifted it off the cornea.

Sometimes there's a dud - it will feel unpleasant when put in - I just take the next and it will be fine. That's because they are cast, not ground to fit.
