I have skied the past several seasons with disposable daily contacts for astigmatism. They are definitely the way forward. You don't have to worry about over glasses goggles and you dont have to fiddle about with solutions in the bathroom so they are more hygenic. I tend to take my glasses to the resort and remove my lenses as soon as i've finished skiing. This seems to stop my eyes drying out too much.
The only issue I find when i'm actualy skiing, is on the rare occasion when it is bright sunlight when i ski into shadow and out again. The rapid change in brightness seems to temporarily upset the lenses and it takes a few seconds for them to settle down again.
