Q: Anyone use contact lenses when skiing?
Q: Could anyone provide any feedback on the use of contact lenses on the slopes?
A: No differences from any other outdoor activity, this is what they're made for. If/when you go to an eye doctor, tell him what you intend to use them for, ... in fact if he doesn't ask you this early in the process, find another doctor.
Q: Do they dry out quickly? Can they fog up?
A: No, and No. If they ever dry up, return to doc and get them corrected quickly, it's a sign of another problem.
I've been wearing contacts for 25+ years, always for outdoor and exercise type situations. Typically wear glasses in an office/work environment anymore, mostly because I'm too lazy to put the contacts in every day, or early in the morning. But in years past I have wore them all the time. Have tried all kinds, too, years ago even used to wear the ones you can sleep in overnight for 14 days, but they didn't work well for me, were uncomfortable. I hear (from eye doc) and read (comsumer reports, etc.) that the new extended wear -- the overnighters -- have newer materials and are cut much better then ever, so are much more confortable. And I'm tempted to give them a try again ... sometime.
The bottom line is find and use a good eye doctor, even go to a contact lens specialist if you have to. I've lived in the midwest, the west coast, and nw the east coast, and each time I moved I spend time looking for a good one. This is just a generalization, but I don't think you'll find the better doctors in the mall/franchise stores, or at Sam's Club and Costco. Better prices for getting the prescriptions filled, yes, but not the same level of quality.
P.S: Avis, if your contacts fall out or dry out, go see your doctor, or find a new one.
